Rhabdomyomatous mesenchymal hamartoma: clinical overview and report of a case with spontaneous regression.

Abstract

A case of cutaneous rhabdomyomatous mesenchymal hamartoma in a 6-year-old Afro-Caribbean girl is reported with review of the literature. The lesions were fine, located on the central face and became inapparent after six months. Spontaneous regression of these lesions has not been previously reported. Although rare, continued reporting will facilitate the elucidation of the clinical features and natural history of these lesions and the relationship to disordered embryogenesis.
