Abstract:
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.
