Leiomyoma of the anal canal originating from the internal anal sphincter is an extremely rare clinical entity. Generally, it does not produce any clinical signs unless it is large enough to cause obstruction, discomfort, bleeding or pain. The diagnosis is often made incidentally during rectal examination due to other perianal disease or check-up. Herein we report a case of internal anal sphincter leiomyoma diagnosed unexpectedly during rectal examination in a patient with perianal fistula, and treated successfully with surgical excision. We present a review of the literature, the diagnostic strategies, differential diagnosis, prognosis and treatment modalities of this lesion.
起源于肛门内括约肌的肛管平滑肌瘤是一种极其罕见的临床病症。一般来说，除非瘤体足够大导致梗阻、不适、出血或疼痛，否则它不会产生任何临床症状。诊断通常是在因其他肛周疾病进行直肠检查或体检时偶然发现的。在此，我们报告一例在肛周瘘管患者直肠检查时意外诊断出的肛门内括约肌平滑肌瘤，并通过手术切除成功治疗。我们对该病变的文献、诊断策略、鉴别诊断、预后及治疗方式进行了综述。
