Nevus sebáceo cerebriforme: uma rara apresentação

Abstract

A 13-year-old boy presented congenital, raised, yellowish colored plaques with fibroelastic consistency, which were velvety in appearance, alopecic, with clearly defined limits and sulci or well-marked meandering invaginations, a cerebriform appearance on the upper part of the right ear, accompanied by alopecia in the temporomandibular region-parietal. The lesion was asymptomatic. Histopathologic examination revealed acanthosis, hyperkeratosis, papillomatosis and follicular plugging in the epidermis. The upper dermis showed underdeveloped hair follicles with sebaceous glands, consistent with sebaceous nevus. There were no skeletal, cardiological, ophthalmological or neuropsychomotor changes; nor were there any records of relevant pathologies in the family history. The patient complained of his appearance, experiencing aesthetic and social issues. Following a diagnosis of cerebriform nevus sebaceous, complete excision was performed with excellent aesthetic results.

“… 1 While histopathologic examination can aid in the diagnosis, findings vary based on the stage. 2 Histopathologic features of early NS include slight papillomatosis, primitive hair follicles, and less prominent sebaceous glands. After puberty, marked acanthosis and papillomatosis of the epidermis can be appreciated along with dilated apocrine glands, prominent sebaceous lobules, and a lack of terminal hair.…”
