Abstract

Adenomyoma of the small intestine is an extremely rare condition characterized by abnormal glandular structures surrounded by smooth muscle. We report a case of adenomyoma of the jejunum. The patient was a 61-year-old female with cancer of the sigmoid colon and multiple liver cysts, who was sent to the operation room for exploratory laparotomy and sigmoidectomy. At surgery, a polypoid lesion was incidentally found in the lower jejunum, which was resected. On histologic examination, the morphologic features were typical of adenomyoma. However, new histopathological and immunohistochemistry features are described here, providing evidence that adenomyoma of the jejunum is a form of intestinal epithelial hamartoma.

摘要

小肠腺肌瘤是一种极为罕见的病症，其特征为被平滑肌包围的异常腺结构。我们报告一例空肠腺肌瘤病例。患者为一名61岁女性，患有乙状结肠癌和多个肝囊肿，被送往手术室进行剖腹探查术和乙状结肠切除术。手术中，在空肠下段偶然发现一个息肉样病变，将其切除。组织学检查显示，形态学特征为典型的腺肌瘤。然而，本文描述了新的组织病理学和免疫组化特征，为空肠腺肌瘤是肠道上皮错构瘤的一种形式提供了证据。
