Benign leiomyomas are common soft tumors, arising especially in the female genital tract; unlike uterine leiomyomas, they rarely occur in perineal regions. They can develop wherever smooth muscle is present. Herein is reported the case of a large perineal leiomyoma in a 36-year-old woman who noted a palpable mass close to the rectum 1 year after she had delivered vaginally, in the same region of as a mediolateral episiotomy. Complete surgical excision was performed. Histopathologic findings were compatible with benign leiomyoma. At postoperative follow-up, no signs of anal dysfunction were noted. There was no pathologic correlation between formation of the leiomyoma and the episiotomy despite a possible association between the presence of fibrosis and development of leiomyomas, which was found during a literature review. Microarray analysis will be necessary to elucidate this hypothesis.
良性平滑肌瘤是常见的软组织肿瘤，尤其常见于女性生殖系统；与子宫平滑肌瘤不同，它们很少发生在会阴区域。平滑肌瘤可发生于任何存在平滑肌的部位。本文报道了一例 36 岁女性的巨大会阴平滑肌瘤，该患者在阴道分娩 1 年后发现直肠附近有一可触及的肿块，位于会阴正中切开术的同一部位。行完整的手术切除。组织病理学检查结果符合良性平滑肌瘤。术后随访时，未发现肛门功能障碍的迹象。尽管文献复习发现纤维化的存在与平滑肌瘤的发生之间可能存在关联，但该平滑肌瘤的形成与会阴切开术之间并无病理相关性。需要进行微阵列分析来阐明这一假说。
