Abstract

Dermatofibroma (DF) is a very common benign tumor, which occurs most often in middle-aged women. In general, DF presents as a solitary lesion on the extremities, shoulders or buttock, which occasionally develops following minor trauma or an insect bite. We describe a case of dermatofibroma involving the dorsum of right hand.

Introduction

Dermatofibromas is common tumor of the skin with considerable clinical and histological variability.

It presents as a solitary lesion on the extremities, shoulders or buttock, in middle-aged women.
We report a case of dermatofibroma affecting the dorsum of right hand.

Observation

A 30-year-old healthy women presented with an  8 month history of an erythematous lesion,  asymptomatic, gradually increasing in size on the dorsum of the right hand.

The dermatological examination revealed a single, well-defined erythematous papule measuring 5*4mm with firm consistency involving the dorsum of the right hand (figure 1). Clinical differential diagnosis of wart was considered. A dermoscopic evaluation showed peripheral pigmented network and central white patch (figure2).

A total excision of the lesion was performed and histopathologic examination revealed a dermal tumor poorly limited, consisting of fusiform cells arranged in short  and storiform bundles, nuclear atypia and mitotic activity were not(figure3).

A diagnosis of dermatofibroma was considered on clinical, dermoscopic, and histopathological correlation.

Discussion

Dermatofibroma is a common benign fibrohistiocytic tumor which uncommonly involves the hands. It occurs most often in middle-aged women. It located predominantly on the limbs and shoulder. DF  presented generally as a single or multiple firm reddish-brown nodules [1].

Different variants of dermatofibroma have been found and they are essentially distinguished by their clinical and histopathological features like common fibrous histiocytoma ,aneurysmal,hemosiderotic, epithelioid, cellular, lipidized, atrophic and clear cell[2].

Several dermoscopic patterns of dermatofibroma are described, of which the most common is central white scar-like patch with pigment network at the periphery [3].

The classical histopathological features include a poorly circumscribed proliferation of spindle-shaped fibroblasts or histiocytes arranged in sheets or interlocking strands with a storiform pattern and collagen trapping[4].

Surgical excision is the recommended management with margin of 3-mm[5].

Conclusion

Dermatofibroma (DF) is a common benign tumor, which affects frequently the  lower extremity .Hand location  remains exceptional.
