Bullous pilomatricoma: a case report

Abstract

A case of bullous pilomatricoma is reported. A 26-year-old man presented with a 7-year history of neoplasm on the right elbow flexor. Dermatological examination revealed a well demarcated, elevated loose blister, sized 3.0 cm×3.0 cm×1.0 cm, on the right elbow flexor. The blister was intact with a hard nodule, about 1.5 cm×1.0 cm×0.3 cm in size, at its base. The nodule was in irregular shape with poor mobility, but without tenderness. Histopathology showed normal epidermis and a dermal tumor composed of basaloid cells and shadow cells. Lymphatic dilation was evident. The tumor was completely removed by resection, and the wound healed well. There was no recurrence during the follow-up.
