“…These findings were supported by the histologic sections in which GISTs consisted of broad bundles, interlacing fascicles, or occasionally whorls of spindle or oval cells with a high cellular density and overall basophilic appearance at low magnification. In Li et al study (17) in which histologic analysis was not performed in about 1/3 of cases, benign and borderline GISTs tended to have cells arranged in tightly cohesive clusters. Malignant GISTs were more likely to exhibit loosely cohesive groups with many single cells, but in the present study all GISTs including eight malignant and one UMP occurred characteristically in closely packed cohesive tissue fragments with a high cellular density.…”

“…Although there have been only a few case reports and series of cases published (14)(15)(16)(17)(18)(19), every diagnosis was not supported by c-kit immunostain (18,19), cytohistologic correlation (16), and histologic diagnoses (16,18). Most of the cases were not correlated with follow-up data (14,17,18). Until recently, GIST treatment consisted of a surgical resection followed by surveillance for metastatic disease.…”

“…The cytological studies on GIST in literature are not comparable as many of the earlier published cytologic studies have combined GIST into a group of neoplasms encompassing leiomyoma, schwannoma, leiomyosarcoma, and an epithelioid leiomyoblastoma [2,5]. However recently, few authors have established EUS-FNAC as a reliable method for diagnosing GIST and EGIST before surgical procedure [3,6].…”
