Rectal leiomyoma is a rare disease. In Japan, only 77 cases were reported before 1984. A study was carried out by compiling information from clinical cases together with two recent cases of rectal leiomyoma. The patients were mainly in their 50s to 60s with a mean age of 53.6 years. The sex ratio of males to females, was 1.5:1. The most common main complaints were anal bleeding and melena and subsequently cylindrical shaped stool or constipation, attributable to rectal stenosis. The tumors were located at 8 cm or less from the anal verge in 87% of the case. Surgery is considered the best method of treatment. Five patients noted a recurrence and three underwent extirpation as their initial operation. Although it is frequently difficult to establish whether leiomyoma is benign or malignant, small lesions (less than 2 cm in diameter) are best treated by local excision.
直肠平滑肌瘤是一种罕见疾病。在日本，1984年以前仅报告过77例。通过汇总临床病例信息以及最近两例直肠平滑肌瘤病例进行了一项研究。患者主要为50多岁至60多岁，平均年龄53.6岁。男女比例为1.5:1。最常见的主要症状是肛门出血和黑便，随后是由于直肠狭窄导致的圆柱形大便或便秘。87%的病例中肿瘤位于距肛缘8厘米或更短处。手术被认为是最佳治疗方法。5例患者出现复发，3例初次手术时进行了切除。尽管通常难以确定平滑肌瘤是良性还是恶性，但小病变（直径小于2厘米）最好通过局部切除治疗。
