A gastrointestinal stromal tumor found in perforated Meckel's diverticulum.

BACKGROUND: Meckel's diverticulum is the most common anomaly of the gastrointestinal tract. It is usually asymptomatic, but approximately 4 % present with complications such as bleeding, intestinal obstruction, and inflammation, while perforation is rare. Carcinoid or gastrointestinal stromal tumors are occasionally found in the resected specimens of Meckel's diverticulum, particularly in the context of perforation.

CASE PRESENTATION: A 62-year-old male with a recent history of admission and evaluation for hematochezia presented with abdominal pain. His physical examination was consistent with peritonitis. Results of laboratory testing were significant for white blood cell count of 32,000/μL. CT scan of the abdomen revealed pneumoperitoneum. During the exploratory laparotomy, perforated Meckel's diverticulum was encountered and segmental bowel resection was performed. Histological examination findings were compatible with gastrointestinal stromal tumor within Meckel's diverticulum.

CONCLUSIONS: While gastrointestinal stromal tumor is a rare finding in Meckel's diverticula, the potential for the coexistence of this and other tumors suggests that segmental resection of the small bowel should be considered in the treatment of perforated Meckel's diverticulum.
