The clinical and pathological features of two cases of retrorectal cyst-hamartoma are presented. Both lesions were characterized by the presence of cysts lined by mucus-producing, ciliated and transitional epithelium. The anatomical and histological findings in our cases of retrorectal cyst-hamartoma are in favor of an embryologic origin from remnants of the postanal gut. The differential diagnosis includes teratomas, dermoid cysts, duplication cysts of the rectum, anal gland cysts, and anal gland carcinomas. To avoid complications, particularly malignant transformation, early complete excision is recommended.
本文介绍了两例直肠后囊肿性错构瘤的临床和病理特征。两种病变均表现为内衬产黏液、纤毛和移行上皮的囊肿。我们的直肠后囊肿性错构瘤病例的解剖学和组织学发现支持其起源于肛后肠残余的胚胎学理论。鉴别诊断包括畸胎瘤、皮样囊肿、直肠重复囊肿、肛腺囊肿和肛腺癌。为避免并发症，尤其是恶变，建议早期完整切除。
