title: [Atypical leiomyoma in a patient with cutaneous leiomyomatosis and mutation of the enzyme fumarate hydratase].
abstract: We report the case of a 56 year-old male with an atypical leiomyoma in the context of a cutaneous leiomyomatosis and a family history of uterine leiomyomatosis. The genetic study revealed a mutation in the gene for the enzyme fumarate hydratase, but he has not had any renal malignancy so far. Atypical leiomyoma is a rare tumor that usually presents as a single lesion and is exceptional in patients with cutaneous leiomyomatosis. The relation between fumarate hydratase enzyme mutations with multiple leiomyomas, uterine leiomyomatosis and an increased risk of developing kidney cancer is widely known. However, the role of these mutations in the development of atypical leiomyomas is still impossible to clarify given the few cases reported in the literature.
