We report herein the rare case of a 39-year-old woman found to have a primary solid dermoid tumor in the rectum. The patient presented after noticing a small amount of anal bleeding, and physical examination revealed a walnut-sized hard tumor, palpable in the anterior rectum, located about 9 cm from the anal verge. Morphologic examinations revealed a polypoid lesion with some hair surrounded by rectal mucosa, and four biopsy specimens from the lesion showed normal squamous epithelium. The tumor, which measured 2.5 x 2.1 x 1.3 cm, was removed by endoscopic polypectomy. Microscopically, the tumor was diagnosed as a solid dermoid tumor without a cyst, a variant type of mature teratoma or dermoid cyst. Since 1914, only 12 such cases, including ours, have been reported in Japan. The clinical features and diagnostic and therapeutic methods applied thereto are discussed.
我们在此报告一例罕见病例，一名39岁女性被发现直肠内有原发性实性皮样肿瘤。患者因发现少量肛门出血就诊，体格检查发现一个核桃大小的硬肿瘤，可在直肠前方触及，距肛缘约9厘米。形态学检查显示为一个有一些毛发的息肉样病变，被直肠黏膜包绕，该病变的四个活检标本显示为正常鳞状上皮。肿瘤大小为2.5×2.1×1.3厘米，通过内镜息肉切除术切除。显微镜下，该肿瘤被诊断为无囊肿的实性皮样肿瘤，是成熟畸胎瘤或皮样囊肿的一种变异类型。自1914年以来，包括我们的病例在内，日本仅报告了12例此类病例。本文讨论了其临床特征以及应用的诊断和治疗方法。
