A rare case report for dermatomyofibroma in nasion.

Dermatomyofibroma is a benign and rare proliferation of myofibroblasts and fibroblasts of the skin. Dermatomyofibroma commonly locates at the shoulder and neck of young adults and adolescents. Other frequently affected anatomic sites are upper arms, thigh, chest wall, back, axillary region and abdomen. Herein, we reported a case of dermatomyofibroma occurred in the nasion. The asymptomatic firm nodule and histopathological features were consistent with dermatomyofibroma. Immunohistochemically, the tumor cells expressed vimentin, HHF35 and α-smooth muscle actin (α-SMA). The patient was followed up for 2 years after excision of the tumors and recurrences were not observed.
