Pilomatricoma (PM) is an asymptomatic, slowly growing, benign skin tumour originating from primitive cells of the hair matrix and hair shaft and appears mostly on the head, neck, and the upper extremities. Typical lesion is usually characterized by a solitary, firm, deep-seated dermal or subcutaneous nodule, covered by normal or erythematous skin, and usually varying in size from 0.5 to 3 cm. Bullous appearance can occur on the lesions of bullous PM and anetodermic PM which are located in the rare atypical forms of PM. Here, we present an 11-year-old girl with an anetodermic PM on her right arm that showed thick-walled flaccid bullous formation over it.
