肛周平滑肌瘤伴直肠下段平滑肌瘤1例

Perianal Leiomyoma with Rectal Leiomyoma:a Case Report

平滑肌瘤较少发生于直肠及肛管,容易误诊。我们报告1例因肛旁肿物就诊的55岁女性患者,磁共振检查显示直肠伴肛周肿块,诊断为恶性肿瘤可能,手术切除后证实为平滑肌瘤。现就本病的临床特点、诊断及鉴别诊断、预后及治疗等方面进行文献复习。

Leiomyomas in the anorectal region were uncommon and were easily misdiagnosed.We reported a case of a 55-year-old female patient who presented with a perianal mass.Magnetic resonance examination revealed a rectum mass accompanied by a perianal mass,which was considered as a potentially malignant tumor.The pathological findings were consistent with leiomyoma.The clinical features,diagnosis and differential diagnosis,prognosis and treatment of this case were reviewed.
