Rectal Mass: A Case Report of Collagenoma
摘要
Collagenomas are rare benign lesions characterized by hamartomatous collagen proliferation, which may be isolated or eruptive. This case describes an isolated submucosal collagenoma in the rectum of a 50-year-old female patient. This case contributes to the literature on rare localized collagenomas, emphasizing the need to differentiate them from other mesenchymal tumors.
