When the majority of malignant cells are isolated: † The isolated malignant cells may be as a result of a variety of neoplastic conditions, but not commonly found in pleural, pericardial, and peritoneal effusions. In contrast, isolated cell pattern is more commonly observed in cerebrospinal fluid (CSF) specimens. 4 Pleural fluid: Cellular evidence of adenocarcinoma. Comment: “Two cell types”; malignant cells in tight clusters and reactive mesothelial cells in the background. The patient had a history of breast carcinoma (PAP, 100×).
B “Fiber” cells, which are slender cells with central, thin, and elongated nuclei. B “Keratin pearl” cells, which are arranged in whorls as they wrap around each other. Necrotic tumor cells from other types of malignancy may show orangeophilic dense cytoplasm, not to be confused with keratinizing squamous cells. Nonkeratinizing Squamous Cell Carcinomas † The cells do not demonstrate cytoplasmic keratinization. The cytoplasm is usually cyanophilic, mimicking adenocarcinoma cells. † The nuclei are round to oval and vary in size.
Comment: “Cell balls” are commonly seen in metastatic breast carcinomas. The patient had a remote history of breast carcinoma and presented with pleural effusion (PAP, 100×). of carcinoma with papillary features. Comment: Papillary cell clusters in effusions may indicate ovarian, lung, and kidney carcinomas and rarely carcinomas of thyroid origin. This patient had a history of renal cell carcinoma and metastatic nodules in the lung (PAP, 60×). 3 Peritoneal fluid: Cellular evidence of adenocarcinoma.
