Tratamento cirúrgico do fibroqueratoma ingueal: relato de caso.

Abstract

Acquired ungual fibrokeratoma is a rare, benign tumor of fibrous origin that affects the nail apparatus, named for the first time in 1977 by Cahan. The first mention of the tumor dates from 1965, described by Steel as a fibroma in a garlic-clove form. The etiology of the tumor is unknown, being related to trauma and previous infections of the nail apparatus. The most used treatment, with greater chances of cure and less recurrence, is the total excision of the tumor by surgery. Others treatment modalities have been described, such as incomplete excisions, shavings, electrosurgery and cryosurgery, with recurrence rates higher than total excision. We report the case of a patient with a 7-year history of a nodular lesion in the hallux, with incomplete excision by shaving, recurrence of the condition and successful re-approach by complete surgical excision with matricectomy. Clinical examination shows nodular, normochromic, hyperkeratotic, firm lesion, approximately 7x5 mm, located between the proximal and lateral nail folds of the left hallux, excised and sent for anatomopathological examination with a result compatible with acquired nail fibrokeratoma. The patient evolved satisfactorily in the postoperative period, with excellent aesthetic and functional results, with no recurrence at a 4-month follow-up.
