PILOMATRICOMA IN THE PREAURICULAR REGION: A CASE REPORT

Pilomatricomas are rare lesions, corresponding to 1% of benign subcutaneous skin tumors, and demonstrating a predilection for the head and neck in children. Clinically, they consist of firm masses that are well delimited, painless, and slowly growing. The mass shows adherence to the overlying skin, which can appear normal, in addition to changes in color, ulceration, and mobility. The present work describes the case of pilomatricoma in a 37-year-old man with a stony hard lesion in the right preauricular area. Punch aspiration showed an absence of material, followed by an excisional biopsy that revealed a 2.7-cm stony hard nodule. After decalcification, microscopic evaluation demonstrated islands of epithelial cells, with basaloid cells in the periphery and ghost cells in the center, with calcified foci and frequent ossification. The patient currently shows no signs of recurrence.
