[Recurrent pilomatricoma on the left eyebrow: case report].
Pilomatricoma is a benign neoplasm originated in the pilosebaceous follicle which appears as an intradermal nodule during childhood, in most cases. It is generally covered with normal skin, reaching a diameter of 1.5 cm on average, and it often shows no recurrence after surgical excision. The authors describe a case in which a 26-year-old patient presented a tumoral lesion on the upper left superciliary area was submitted to total excision, and diagnosed as pilomatricoma by the histological study. According to the patient, this lesion had a progressive and slow growth of about two years. Eight months after the first surgical intervention, there was a new tumor growth in the region, this time quicker and worsen, with ulceration on the small skin area that covered the lesion, thus leading to malignity suspicion. After the conduction of a new excision within a security margin, the histological test confirmed that it was a pilomatricoma lesion and the piece displayed no sign of malignity. The patient has been followed up for one year, showing no signs of recurrence so far.
