Vulvar leiomyosarcoma: a case report in a Nigerian woman.

Leiomyosarcoma of the vulva is a rare gynaecological malignancy. To date, only few cases have been reported in the literature, the majority of which are from Western countries. Although leiomyosarcoma is classically regarded as a malignant tumor, the generally favorable prognosis following surgical treatment, as well as its reduced propensity for widespread metastasis, makes it one of the most enigmatic malignancies in the medical literature. In addition, the tumor may attain enormous morphological proportions, a situation unusual in many malignant tumors.
