Multiple pilomatrixomas and myotonic dystrophy: a case report.

Clinical and histopathological data of a patient affected by myotonic dystrophy (Steinert Disease) and multiple pilomatrixomas (calcifying epithelioma of Malherbe) are reported. This association has been previously reported in other 16 cases. The prevalence of pilomatricoma in myotonic dystrophy results much greater than in general population. This association affects females as well as males. This tumour, when associated with myotonic dystrophy, is more frequently multiple than single.
