title: Diagnosis of metastatic carcinoma of stomach using fine catheter aspiration cytology.
abstract: The value of fine catheter aspiration cytology organs of the peritoneal cavity in the diagnosis of a metastatic carcinoma is illustrated by this case report. The finding of unequivocal malignant cells was quite unexpected and led to an investigation of the gastrointestinal tract which demonstrated a primary carcinoma in the stomach. This was further confirmed on a biopsy of the tumor and cell block preparations of aspirated material on which immunostaining was done and which further substantiated the light microscopic cytohistologic diagnosis. The findings presented in this article further emphasize the value of fine catheter aspiration cytology in not only identifying tumor type or predicting the source of the primary but also in managing patients admitted with abdominal pain as an emergency who may be saved from an unnecessary laparotomy which would have otherwise been done for a diagnosis.
