title: Lesions With an Epidermal Hyperplastic Pattern: Morphologic Clues in the Differential Diagnosis.
abstract: In this report, we review the most common entities that show a epidermal hyperplastic pattern in the biopsy. These entities include inflammatory, reactive, infectious, hamartomatous, and tumoral conditions, each with a very different prognosis. Therefore, an approach based on the classic "patterns and clues" tools used in dermatopathology can bring a lot of information to the dermatopathologist or the general pathologist evaluating these lesions.
