Primary signet ring cell carcinoma of the pancreas: Cytopathology review of a rare entity.

abstract：:A case of granulocyte colony-stimulating factor (G-CSF)-producing small-cell carcinoma of the uterine cervix is described. In a 70-yr-old woman, clusters of small cells with hyperchromatic nuclei at a high nuclear/cytoplasmic ratio were detected cytologically in the cervix. These clusters were diagnosed as a small-cel...
