Abstract
A 52yearold woman with a history of splenectomy for a splenic injury 45 years earlier underwent investigations for a preexisting gynecologic disease Contrastenhanced abdominal computed tomography CT and magnetic resonance imaging MRI showed a tumor 3 cm in diameter adjacent to the sigmoid colon suggestive of a gastrointestinal stromal tumor GIST Laparoscopic exploration revealed a white mass protruding from the subserosa of the sigmoid colon and we performed laparoscopicassisted sigmoidectomy to rule out a GIST Pathological studies showed splenic tissue thus confirming a diagnosis of splenosis given the history of splenic injury This case of splenosis mimicking GIST following splenic injury was diagnosed correctly and treated successfully with laparoscopic surgery To our knowledge this is the first case of splenosis treated with laparoscopic colectomy with no tumor extirpation
