A rare case of a heavily calcified gastrointestinal stromal tumors with an intraluminal growth pattern.

Gastrointestinal stromal tumors (GISTs) are unique neoplasms that occur throughout the gastrointestinal tract, mesentery, omentum, and retroperitoneum. Because most GISTs arise within the muscularis propria of the stomach or intestinal wall, GISTS most commonly have an exophytic growth pattern; intramural and intraluminal masses are less common manifestations. Calcification is an unusual feature of untreated GISTs (1,2). Herein we describe a rare case of a heavily calcified GIST with an intraluminal growth pattern.
