Abstract :
Before the advent of specific immunohistochemistry (IHC), many Gastrointestinal Stromal Tumors (GISTs) were misdiagnosed as Leiomyosarcoma (LMS) of the gastrointestinal tract (GIT), given their similar morphology. However, its true incidence is extremely low with only a few reported cases of Leiomyosarcoma of the stomach in literature. Here, we present a rare case of LMS of the stomach with metastasis to the liver and lymph node, discussing the diagnostic challenges faced, based on its clinical, cytological, and histomorphological features.
