Fine needle aspiration cytology(FNAC) of GIST: cytomorphological features

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors arising in the gastrointestinal tract and occasionally in mesentery and omentum. Fine needle aspiration cytology combined with immunocytochemistry has been shown to be quick and reliable diagnostic tool for diagnosis of primary and metastatic GIST. Patients and Methods: We present five cases of GIST preoperatively diagnosed on MGG stained cytologic slides. Material was obtained by percutaneous US-guided FNA in four cases and by transrectal FNA with Franz&egrave ; ; ; ; ; ; n needle in one case. Immunocytochemistry was performed on cytologic smears in three cases and since tumor cells were positive for CD 117 definitive diagnosis was given. In other two cases diagnosis was mesenchymal tumor, probably GIST...
