We report a case of a 69-year-old woman with endometrial mucinous adenocarcinoma distinguished histochemically from clear cell adenocarcinoma and anatomically from endocervical adenocarcinoma. Endometrial cytology showed papillary shaped tumor cell clusters and bubbles in cytoplasm.
We report a rare case of rosette-forming thymoma. Imprinting cytology specimens from the tumor showed tumor cells arranged in small clusters with radial fibrous bands on their surface. These cells also showed epithelial cells without cellular atypia. These cytological findings were helpful in distinguishing this tumor from a carcinoid tumor or thymic cancer. Although 2 years have passed since surgical resection, the patient is mostly well and has no tumor recurrence. To our knowledge, this is the first report on cytological figurs in a tumor.
We report a case of tongue cancer found by sputum cytology in mass screening. Atypical squamous cells were detected in a sputum cytology specimen from a 70-year-old man. After 2-year follow-up with sputum cytology. a lesion was found and diagnosed as poorly differentiated squamous cell carcinoma of the tongue. Compared to lung cancer, cancer cells of the tongue showed more frequent bizarre squamous cells. Glassy cytoplasm of orangephilic cells was common and nuclear chromatin of light green cells was fine. Sputum cytology is thus effective in diagnosing tongue cancer and lung cancer or pharyngeal cancer.
