We report metastatic cytological findings in ovarian clear cell adenocarcinoma. A 54-year-old woman diagnosed with ovarian clear cell adenocarcinoma stage HI developed a nodular lesion and hematuria after surgery and chemotherapy. Imprint cytology from the cutaneous tumor showed large nuclei with prominent nucleoli and abundant clear cytoplasm. Urinary cytology showed many clusters including a hobnail pattern. Tumor cells had clear cytoplasm and round nuclei with prominent nucleoli Although cutaneous or urinary cytological findings in clearcell adenocarcinoma are rare. it is important to observe the in cytoplasmic character and cluster patterns.
We report a case of ovarian carcinosarcoma with a heterologous element diagnosed with ascites cytology. A 41-year-old woman was admitted because of huge ascites, the cytological specimen of which showed isolated large cells with irregular nuclei and giant pleomorphic round cells surrounding a mucinous background. Histologically, the ovarian tumor was diagnosedas carcinosarcoma with chondrosarcoma. In this case, we were able to diagnose ovarian earcinosarocnia from the ascites cytology. because of rupture of an ovarian tumor and disseminating of the chondrosarcomaous elements.
We report cytological features for an autopsy case of moderately differentiated gastric tubular adenocarcinoma showinghepatoid differentiation in metastatic lesions. At autopsy, imprint cytology of pulmonary metastases showed two different types of malignant cells; one arranged in an acinar pattern, suggesting features of moderately differentiated adenocarcinoma, and the other composed of cancer cells resembling cytological features of hepatocellular carcinoma. An accurate diagnosis ofhepatoid adenocarcinoma is very important because of the miserable prognosis, making the cytological findings from our present case useful in differentiating between hepatoid adenocarcinoma and common types of adenocarcinoma.
