A Rare Cause of Abdominal Pain and Diarrhea-cystic Lymphangioma Located in the Descending Colon

Cystic lymphangiomas of the colon are rare, benign tumors that arise from the lymphatic vessels and are typically asymptomatic.These lesions are often discovered incidentally during imaging or endoscopic evaluations for unrelated conditions.We report a case of a 57-year-old woman who presented with abdominal pain and diarrhea.Imaging studies revealed a submucosal cystic mass in the descending colon, and endoscopic evaluation confirmed the presence of a cystic lesion.Histopathological examination following biopsy confirmed the diagnosis of cystic lymphangioma.The lesion was successfully resected via colonoscopy, and the patient had an uneventful recovery.This case highlights the importance of considering cystic lymphangiomas in the differential diagnosis of gastrointestinal masses and underscores the value of endoscopic techniques for diagnosis and treatment.
