Linear dermatomyofibroma over the nape of neck: a report of an unusual case and literature review

Abstract

Dermatomyofibroma is a rare cutaneous mesenchymal tumor of benign fibroblastic and myofibroblastic derivations. It predominantly affects young women, and it usually presents as a reddish-brown plaque or nodule, which is commonly located over the upper trunk. We report the case of a 41-year-old female patient who presented with progressive linear dermatomyofibroma over the nape of her neck. This case report expands the knowledge about the clinical and histopathological features of this rare, benign and cutaneous tumor.

“…DMF predominantly affects postpubescent females and prepubertal male children. 1,2 Therefore, to diagnose in an adult male as this 39-year-old patient is extremely rare. DMF has a predilection for the shoulder, neck, and upper trunk, followed by the axilla and the limbs.…”

“…Annular, linear, and Blaschkoid configuration is unusual. 1 The largest lesion of DMF can reach up to 13 cm in diameter. The patient usually undergoes a development period following stabilization or slow growth.…”
