Pilar leiomyomas: New dermoscopic pattern

Author Affiliation(s)

Case Presentation

A 60-year-old woman, with a personal history of a uterine fibroma, was seen for evaluation of multiple flesh-colored, erythematous papules and nodules localized on latero-cervical regions. Dermoscopic examination of all lesions revealed multiple shiny and whitish areas distributed homogeneously within a fine network in a single nodule ( Figure 1, A and B ). The histological investigation confirmed a pilar leiomyoma.

Teaching point

The dermoscopic features of pilar leiomyoma tumor are not well defined, because of its rarity. It is similar to dermatofibroma with central hypopigmented area and peripheral network [ 1 ] . In our case the lesions presented widespread bright white areas, with a more regular shape respect to the “white like-cloud areas” reported by Diluvio et al [ 2 ] .
