Keloidal Dermatofibroma: A Rare Diagnostic Entity.

Abstract

Dermatofibroma, also referred to as benign fibrous histiocytoma, is a cutaneous tumor frequently occurring on the extremities. Its occurrence on the neck is linked to atypical clinicopathologic characteristics and a more aggressive clinical course compared to typical cases. Furthermore, prior studies have recognized benign fibrous histiocytoma as the predominant subtype, while the keloid variant is extraordinarily rare, constituting approximately 1% of documented cases. In this case study, the exhibited nodular lesion is on the neck region. Upon histopathological examination, the tumor demonstrated well-circumscribed features with keloid-like regions, occasional spindle cells with elongated nuclei and eosinophilic cytoplasm, and a prominent inflammatory infiltrate. The objective of this study was to report our experience with a case of keloidal dermatofibroma occurring on the neck, a condition frequently overlooked in clinical practice, and to critically examine the management strategies for keloidal dermatofibromas at this anatomical site.
