Fibroepithelioma of Pinkus: Dermoscopic and reflectance confocal microscopic patterns.

As the diagnosis determines therapy, it is important that the tumor is identified correctly. Dear Editor, Fibroepithelioma of Pinkus (FeP) is an uncommon subtype of basal cell carcinoma (BCC) with a particular growth pattern, first described by Hermann Pinkus in 1953.1 This tumor is slow growing and commonly found on the trunk or extremities of persons in the fifth and sixth decades of life.2 Although its etiopathogenesis is not fully understood, chronic ultraviolet damage seems to be a lesser factor than it is in BCC.3,4 Mutations in the PTCH gene of the Hedgehog signaling pathway could be involved in its development.5 FeP arising after radiation therapy has been reported, although a direct link is yet to be defined.6 FeP is a rare neoplasm that is often difficult to diagnose, as it simulates other skin tumors. The differential diagnosis was modified to include FeP, BCC, and seborrheic keratosis. [Extracted from the article]
