Introduction: Lymphangiomas are benign malformations of the lymphatic system that are uncommon and often misdiagnosed. They are rarely found in the gastrointestinal system and are exceptionally rare in the anal canal.

Case Description/Methods: We present the case of a 47-year-old female with no significant personal or family history who underwent a screening colonoscopy with findings of a suspected hypertrophic anal papillae with atypical endoscopic findings. Biopsies were obtained showing a lymphangioma. Given location the patient was referred to colorectal surgery for complete excision.

Discussion: Lymphangiomas are uncommon and can occur anywhere in the skin mucosal membranes. Most common sites of location being the head and neck although they can be seen in the small intestine, pancreas, and mesentery. Sometimes these lesions can be confused with malignancy or other benign neoplasm such as lipomas, papillary hidradenoma, and epidermal cyst. Given this differential it is suggested for complete excision of lesion due to possibility of missing a histological diagnosis. This is his only the fifth documented anal canal lymphangioma to our knowledge.
