A Rare Case of a Gastrointestinal Stromal Tumor (GIST) Presenting as a Perforated Meckel’s Diverticulum

Excerpt

Meckel’s diverticulum (MD) is the most common congenital malformation of the gastrointestinal tract, with an estimated incidence of 1.2 to 4 % [1, 2]. Despite this high prevalence, complications are uncommon, with recent literature suggesting a lifetime complication risk of 4 to 16 %. The most frequent complication is GI hemorrhage associated with ectopic gastric tissue, especially in children. However, obstruction, intussusception, Meckel’s diverticulitis, ulceration, perforation, and neoplasm are also seen [2]. MD is an uncommon location for malignant tumors, with an incidence of 14.4 per 100 million person-years [3]. Gastrointestinal stromal tumors (GISTs) in a MD have an incidence of 1.5 per 100 million person-years [3]. Perforation of a GIST in a MD is an even more rare occurrence, with only 10 cases reported in the literature, and none originating in the USA [4‐13]. Here, we describe a case of a GIST presenting as a perforated Meckel’s diverticulum. …
