Cellular digital fibromas: distinctive CD34‐positive lesions that may mimic dermatofibrosarcoma protuberans

Abstract

These findings suggest that a subset of digital fibromas is characterized by a dense cellular proliferation of CD34-positive spindle cells. Awareness of this variant of digital fibroma and its staining pattern is critical in preventing misdiagnosis as dermatofibrosarcoma protuberans, particularly in superficial biopsies.
