title: Histologic variants of fibrous papule.
abstract: Fibrous papules (FPs) are common benign lesions usually of the face. Most are readily recognizable histologically, although several variants exist that may not be as easily diagnosed. These include hypercellular, clear cell, pigmented, pleomorphic, and inflammatory variants. A granular cell variant has also been described. We microscopically evaluated 212 FPs, and of those, 184 demonstrated features of one of the variants. We conclude that variants of FP may be encountered not uncommonly. Dermatopathologists should be aware of these to avoid misdiagnosis.
