Superficial perineal leiomyosarcoma in an adolescent female and a review of the literature including vulvar leiomyosarcomas.
Superficial perineal leiomyosarcomas are rare, with only three previously reported examples. We encountered a superficial (deep subcutaneous) perineal leiomyosarcoma in a 17-year-old female. At follow-up two years after a wide excision, there were no signs of recurrence. The tumour was well differentiated and showed immunoreactivity for alpha-smooth muscle actin and desmin. A review of the literature on superficial leiomyosarcomas indicates that superficial perineal leiomyosarcomas may be more aggressive than superficial leiomyosarcomas in general. As the presented tumour occurred in a female, it was compared with vulvar leiomyosarcomas.
