JOURNAL FREE ACCESSVarious problems on the cytodiagnosis of lung cancers, such as following respects, were presented and discussed from a practical point of view.
1. Unusual metastasis into the lungs.
2. Unexpected recurrences of squamous cell carcinoma in the pulmonary hilus, even if the primary cancer was extripated at the early developmental stage.
3. A toxonomic consideration on the neuroendocrine lung tumor, probably derived from Kulchitzky cell.
4. Background of false positive reports in cytologic diagnosis.
These problems are considered as to arise partly from the complicated and unsolved clinico-pathologic backgrounds respectively.View full abstractDownload PDF (29682K) -

JOURNAL FREE ACCESSIn order to establish the cytological criteria in diagnosing adenomatous hyperplasia of the endometrium, thirty-one cellular samples from the hyperplasia and those of twenty from the proliferative phase of normal endometrium were studied retrospectively. All samples were obtained from endometrial cavity by Endocyte technique and stained with Papanicolaou method.
Factors which were found in adenomatous hyperplasia with higher incidences were realized to be 12 including those concerning clusters;(1) projectional structure just like a peninsula on the irregular margin of clusters, (2) papillary structure on the irregular margin of clusters, (3) small irregular-shaped clusters, (4) clusters with cells protruding from the margin and (5) back-to-back tendency of glands and stratification of epithelial cells, factors concerning nuclei;(6) increased nuclear size and anisokaryosis, (7) irregularshaped nuclei, (8) thickening of a nuclear border, (9) increased chromatin, (10) appearance of nucleoli and (11) irregularly arranged nuclei, and (12) dirty-looking background in the specimen. Among these 12 factors 8 were assured to be statistically significant by x2 test.
The results indicate that cases with more than 8 out of 12 factors (38.7%) will be predictable to make cytological diagnosis of adenomatous hyperplasia and those with 5-7 factors (41.9%) will be screened, whereas those with less than 4 (19.4%) will be unable to screen. The predictive incidences by using 8 statistically significant factors were 45.2%, 41.9% and 12.9%, respectively.View full abstractDownload PDF (6483K) -

JOURNAL FREE ACCESSIn order to evaluate pregnancy specific endometrial changes cytomorphologically. Especially the Arias-Stella reaction, we obtained endometrial specimens by either aspiration cytology, or curettage. The specimens selected for evaluation were all positive for the reaction on pathology studies. The cases consisted of two missed abortions (hypersecretory type 1 case, proliferative type 1 case), both in the second month of pregnancy; One invasive hydatidiformmole (proliferative type); and one choriocarcinoma of the Fallopian tube (left tube and hypersecretory type)
The cytologic characteristics in these specimens were as follows:
1. Large Nuclei.
2. Nuclei typically round or oval, but even irregular and indented nuclei were present.
3. Intranuclear featuers: Nuclear membranes are grooved wrinkled (appear crumpled) and the nuclei are irregular in size, depending on the severity of the lesion. In mild lesions, the nuclear membranes were not thickened, the chromatin finely granular and nucleoli not readily observable. In contrast, more severe specimens revealed thickened nuclear membrane with distinct nucleoli and hyperchromatism. The more severe lesions require differential diagnoses to rule out malignancy.
4. The cytoplasm in abundant and appears either sheetlike or honey combed. Althongh there is some evidence of overlapping the cytoplasmic periphery appears distinctly mosaic in nature.
5. In the hypersecretory type, the cytoplasm contains an abundance of red staining secretory granules.View full abstractDownload PDF (13219K) -

JOURNAL FREE ACCESSThe correlation between uterine cervical lesions and human papillomavirus (HPV) was studied by dot blot and Southern blot hybridization (HPV-DNA Diagnostic Kit FO-8830)
1) HPV genomes were detected in 2%(2/100) of patients without abnormal cytologic findings in the uterine cervix.
2) HPV genomes were detected in 31.0%(45/145) of patients with abnormal cytologic findings in the uterine cervix. Five of the seven patients (71.4%) between 20 and 30 years of age were positive for HPV-DNA.
3) HPV genomes were detected in 100%(2/2) of patients with condyloma acuminatum, in 40.9%(27/66) with mild to moderate dysplasia, 40.0%(6/15) with severe dysplasia, in 100%(1/1) with carcinoma in situ and in 70%(7/10) with invasive cancer.
4) In the correlation between the uterine cervical lesion and HPV types, types 6 and 11 were not found in patients with dysplasia and cervical cancer. They were found in both patients with condyloma acuminatum. Type 16 was found in 19 patients (14 with dysplasia and 5 with cervical cancer). Type 31 was found in 27 patients (21 with dysplasia and 6 with cervical cancer: 60% of positive patients by dot blot hybridization).
5) A 84.8% consistency rate was obtained between the methods using HPV-DNA Diagnostic Kit: FO-8830 and Vira Pap in the detection of HPV-DNA. Accurate follow-up and accumulation of patients seems to be needed to clarify the relationship between HPV infection and uterine cervical lesions.View full abstractDownload PDF (3322K) -

JOURNAL FREE ACCESSExfoliative squamous cells on a slide-glass-sized x-ray film obtained from the uterine cervix, were examined by light microscopy (LM). The portion of the smear where the target cells were observed was cut out, dried by the critical point drying technique (CPD), and examined by scanning electron microscopy (SEM). Then the target cells were embedded in Epon 812 Resin. Ultrathin sections were made and examined by transmission electron microscopy (TEM). The preparation for this study was as follows.
1) For TEM examination, the cells were fixed with paraformaldehyde, glutalaldehyde and osmic acid. But the fixation resulted in a marked change in the color of Papanicolaou staining. To avoid this discoloration, the Papanicolaou's method was modified.
2) CPD, used for preparing the cells for SEM examination, mode the cells insufficient to the penetration of Epon 812 Resin, which was necessary to preserve the intracellular ultrastructure for the subsequent TEM examination. To resolve the problem, complete rehydration of the cells after SEM examination was performed. Thus, it became possible to make a study of cells through consecutive LM-SEM-TEM examination.
Using the technique, cells of the superficial, intermediate and basal layers of the squamous epithelium, dyskaryotic cells of the intermediate layer, a dysplastic cell from a case of squamous cell carcinoma which was diagnosed by LM as a degenerated megalocyte, an atypical cell collected in swabs from a condylomatous lesion and atypical cells of the superficial layer in a Vira Pap positive case were examined by the consecutive method. As a result, many new findings which have never been observed were seen. A technique which allows the examination of the same exfoliated cells by the consecutive LM-SEM-TEM method has almost been established and the usefulness of this technique has been demonstrated.View full abstractDownload PDF (16651K) -

JOURNAL FREE ACCESSAs a basic study for the identification of the origin of exfoliative cells in ascites, cells in ascites derived from ovarian tumors of different types and a peritoneal serous membrane were studied. Each preparation was consecutively examined by light microscopy (LM) and scanning electron microscopy (SEM) or by LM, SEM and transmission electron microscopy (TEM). The results are described as follows.
1. In the tissue of a peritoneal serous membrane, the ultrastructure of the cell surface was characterized by the sporadic presence of thin long microvilli (MV). In exfoliative mesothelial cells collected from ascites, each of the MV had a markedly enlarged tip, showing a bleblike structure.
2. Both tissues of serous cystoadenocarcinoma and serous cystic tumor of borderline malignancy had short MV and occasionaly projections of cilia on the surface of the cells. Exfoliative cells derived from serous cystoadenocarcinoma in ascites had rod-shaped MV, being different from those observed in the tissue.
3. Cells prepared from imprint smears of mucinous cystoadenoma and mucinous cystoadenocarcinoma had projections of folds, membranes, and spheres. Secretory granules had gathered immediately below the folding cell membrane.
4. By SEM examination, both tissues of endometrioid adenocarcinoma and its exfoliated cells in ascites had relatively long MV as a basic structure.
The present study succeeded in disclosing findings characteristic of the ultrastructure of the cell surface of tumor tissues and exfoliative cells. The study is not only a useful method to differentiate exfofoliative mesotherial cells from cells derived from ovarian tumors, but also to identify the various kinds of cells.View full abstractDownload PDF (15818K) -

JOURNAL FREE ACCESSThe authors studied the effectiveness of expectorant for sputum induction. Trans-4-[(2-amino-3.5-difromobenzyl) amino] cyclohexanol hydrochloride was used. Thirty five healthy males participated in this study. The average age was 39 years old and 16 men were smokers and 19 were non -smokers. They were divided into 3 groups, non-administration group (A) of the drug, administration group (B) with 45 mg of the drug and (C) with 90 mg. This study was performed by the cross-over method. The period of drug administration was for days with a 4-day washout period. The ease and frequency of expectoration of sputum by the quetionnaire, the nature of sputum with relation to the influence of smoking, quantity of respiratory tract cells including squamous cells, ciliated columnal cells, squamous metaplastic cells and inflammatory cells, and alveolar macrophages in sputum were evaluated in these 3 groups by the Wilcoxon examination.
In the questionnaire the ease of expectoration of sputum was improved in the groups with the administration of drug and the frequency also increased. A quantitative study of the respiratory tract cells and alveolar macrophages did not show any statistical difference between smokers and nonsmokers. However respiratory tract cells and alveolar macrophages increased in the groups with administration of drug.
The administration of trans-4-[(2-amino-3.5-difromobenzyl) amino] cyclohexanol hydrochloride was effective for the sputum induction.View full abstractDownload PDF (1030K) -

JOURNAL FREE ACCESSPrimary carcinoma of the fallopian tube is a very rare disease. The incidence of this disease is 0.12-1.6% of all gynecologic malignancies. It is very difficult to find carcinoma of the fallopian tube in its early stage.
A case of microinvasive carcinoma of the fallopian tube was reported.:
The patient was a 54-year old female.
Endometrial aspiration cytology revealed metastatic adenocarcinoma. Endometrial curettage was negative for cancer. Hysteroscopy, ultrasono-graphy and CT scan showed no remarkable findings.
Since fallopian tube carcinoma or early ovarian carcinoma was highly suspected, total hysterectomy and bilateral salping o-oophorectomy was performed.
Macroscopically ovaries and tubes were unremarkable, but histologically, primary microinvasive carcinoma of the fallopian tube was found.
In the endometrial aspiration smear, many clusters of tumor cells arranged papillary and partly tubular, were observed in clean background. The cytoplasm contained fine vacuoles which looked like lace. The nuclei were oval or spherical with finely granular chromatin. N/C ratio was high. Nucleolei were prominent.
Histological examination revealed papillary, partially tubular adenocarcinoma at the ampulla of the right tube. The lesion was intraepithelial with microinvasive.View full abstractDownload PDF (3707K) -

JOURNAL FREE ACCESSA rare case of verrucous squamous cell carcinoma of vagina is reported. The cyto-histological features of this case were studied by means of transmission electron microscope and light micro-scope. HPV screening by in situ hybridization was done.
Cytologic examination revealed a large number of dysplastic cells with features of intermediate to parabasal cell type having cyanophilic stainability.
Histological examination showed papillary growth with a marked tendency of keratinization, which involved irregular fibrovascular cores. A site of basement membrane ruptures was also recognized. Koilocytosis was not remarkable.
Detection for HPV revealed positivity in type 6 and 11, showing strong suggestion for HPV infection.
Transmission electron microscopic observation revealed various degree of anaplasia of nuclei and poorly developed organella. Well developed desmosomes and tonofilaments with keratohyaline granules were also demonstrated.
Above morphological feature it's able to discriminate this case from either condyloma and papilloma.View full abstractDownload PDF (10648K) -

JOURNAL FREE ACCESSWe described cytologic features of aspiration biopsy of a splenic solitary cyst formed by metastasis of ovarian carcinoma. The patient was a 74-year-old woman who had a history of bilateral adnexotomy and total hysterectomy 9 years before for left ovarian carcinoma and presented with complaint of the left flank pain. The examinations by CT scan, MRI scan and ultrasonography detected nothing abnormal except a cystic tumor of the spleen, and laparotomy was done under the clinical diagnosis of splenic lymphangioma. An aspiration cytology of the splenic cyst during operation revealed papillary clusters of atypical cells with prominent nucleoli and vacuolated cytoplasm, wich could be diagnosed as adenocarcinoma cells. The resected spleen weighing 220 g was almost replaced by a multilocular tumor with areas of solid lesion. Histologically the tumor resembled serous cystadenocarcinoma of ovarian primary.View full abstractDownload PDF (6372K) -

JOURNAL FREE ACCESSTwo cases of adenoid cystic carcinoma originating in the submandibular gland are presented in this paper. Cytological features observed on fine needle aspiration smears were as follows.
1) The tumors in both cases were composed of uniform small cells with darkly stained naked nuclei, and formed irregularly shaped clusters showing cribriform, ball-like, sheet-like, or glandular patterns.
2) As the tumor cells showed several different patterns on Alcian green staining (Yamamoto method, Al-G), the were divided into three cytological subtypes: cribriform, glandular, or solid patterns, as in the histological classification. The cribriform pattern, which contained pseudocystic spaces filled with myxoid or hyaline substances, was stained entirely and intensely bluish by Al-G. Of the two patterns lacking myxoid substances, in the glandular pattern lumens of clusters were stained bluish, whereas in the solid pattern, the cores of the cluster were stained bluish and graded into pale blue at the edge of the cluster.
The cytologic features as shown by Papanicolaou and Al-G stains can be indicative of adenoid cystic carcinoma and be useful in differentiating the various subtypes of this tumor.View full abstractDownload PDF (10129K) -

JOURNAL FREE ACCESSThis paper describes the cytologic and histopathologic findings in four congenital neuroblastomas removed from the retroperitoneal space shortly after birth. In three cases, the tumor were found in adrenal glands, and other in lumbal sympathetics. Histologically, two cases were diagnosed as rosette forming typed neuroblastoma, and other cases were round cell type. Cytological examination by touch preparations were mainly composed of small immature cells with rosette and fibrillary stroma compatible with neurogenic malignancy (neuroblastoma). The summary cytological characteristics of all cases were as follows: 1) In all cases, formation of the Homer-Wright rosette were to some extent seen. 2) The tumor cells were small in size and almost one round-to-oval nucleus with a thin rim of basophilic cytoplasm increased N/C ratio. 3) In three of the four cases, nuclei were composed of highly chromatin with coarsely granular pattern, and their nuclei were somewhat irregular in size. 4) Slightly increased mitotic activity was seen in all case. 5) Cytoplasmic processes and a fibrillary matrix were seen all cases.
These findings mentioned above are almost same to those of the previously reported cases. However in present cases, the rosettes and fibrillary matrix were recognized more frequently, and multinuclear cells were not found. These differences might be due to congenital typed compared with usual neuroblastoma which were previously reported in literature.View full abstractDownload PDF (10948K) -

JOURNAL FREE ACCESSProliferative myositis is a rare pseudosarcomatous lesion of muscle and is often misdiagnosed as a malignant neoplasm because of its high cellularity and the presence of bizarre giant cells. In this report, two such cases arising in the muscles of the thigh are presented, and the available literature has been reviewed. Microscopic findings of the excised tumor were characterized by ill-defined proliferation of ganglion-like giant cells and fibroblasts with a sparse lymphocytic infiltrate and hemorrhage into the muscle involving the neighboring fascia. Histological and cytological differentiation from malignant neoplasms is important and can be made if one is aware of histological characteristics of proliferative myositis.
The histogenesis of the ganglion-like giant cells was thought to be from mesenchymal cells with fibroblastic differentiation originating in the fascia.
The etiology of the lesion is obscure, but occasional association with trauma, degenerated muscle and hemorrhage suggests a relationship injury.View full abstractDownload PDF (11532K) -

JOURNAL FREE ACCESSA rare case of primary squamous cell carcinoma of the left breast was reported.
A lactating 28-year-old female presented with chief complaint of “a lump in the left breast.” Needle aspiration yielded scattered tumor cells which were elongated, tadpoleand oval-shaped with deeply eosinophilic or light green cytoplasm against a background of necrotic debris and inflammatory cells. The tumor cells exhibited cytoplasmic keratinization and were arranged in cannibalistic patterns. These findings are the routine diagnostic features of squamous cell carcinoma.
An intraoperative imprint smear contained only a bery few carcinoma cells which resembled ductal carcinoma cells, i.e., were clustered, had foamy cytoplasm, a granular chromatin pattern, and prominent nucleoli in addition to squamous carcinoma cells. The resected tumor measured 3.5×3.0 cm in diameter, and featured a cyst within the tumor, 2.5×1.5 cm in diameter in its central area. The histopathological diagonosis was primary squamous cell carcinoma of the breast.View full abstractDownload PDF (6857K) -

JOURNAL FREE ACCESSA case of fibrolamellar hepatocellular carcinoma (FHC) with liver cirrhosis is reported. A 56-year-old man was found to have two solitary masses located in the caudate and the left lobe of liver, respectively. These two tumors were diagnosed pathologically as FHC and ordinary-type hepatocellular carcinoma. In touch preparations of the FHC in the caudate lobe of the liver, tumor cells were present singly without adhering and were round to polygonal in shape with deeply eosinophilic granules in abundant cytoplasm. Enlarged nuclei were round with single prominent nucleoli. The N/C ratio was not increased. Fibroblasts were characteristically interposed among these tumor cells. Intracytoplasmic vacuoles (pale bodies), globular hyaline bodies, intranuclear cytoplasmic inclusions, and bile production were also observed. There were some multinucleated giant cells and naked neoplastic cells with no evidence of mitosis or necrosis. Histologically, oncocytic neoplastic hepatocytes were seen together with fibrosis arranged in a lamellar pattern. The second tumor in the left lobe exhibited the cytologic and histologic features of the ordinary-type of hepatocellular carcinoma.View full abstractDownload PDF (9970K) -
