In this largest case series of cytomorphological diagnosis of GIST, we describe the cytomorphology and immunocytochemistry of primary and metastatic GIST. GISTs with predominant epithelioid cell morphology may pose a diagnostic dilemma therefore in all suspected cases of GIST, immunocytochemistry for c-KIT and/or DOG1 should be employed on cell-block preparations to confirm the diagnosis of GIST.
