Perforating Fibrous Histiocytoma Mimicking Keratoacanthoma: A Case Report

Dermatopathology (Basel). 2023 Dec 25;11(1):8-12. doi: 10.3390/dermatopathology11010002.

Abstract

A 31-year-old male presented with a firm, well-demarcated, erythematous, crateriform, and ulcerated nodule in the left lumbar region, which persisted for 3 months. Clinically, a keratoacanthoma was suspected. The histological analysis was consistent with perforating fibrous histiocytoma, a rare histopathologic variant of fibrous histiocytoma. To our knowledge, this is the third case reported in the literature.

Keywords: dermatofibroma; histopathology; perforating; perforating fibrous histiocytoma.
