Abstract

Mammary hibernomas are extremely rare benign tumors composed of brown fat cells, with only five cases previously reported in the literature. We report the case of a 42-year-old female patient with a painless growing mass in her right breast. A partial mastectomy was performed, and the diagnosis of hibernoma was confirmed by the histological features and the immunohistochemical profile. Although hibernoma is a benign tumor, its main differential diagnoses include aggressive lesions, making the accurate diagnosis essential to provide adequate care to the patient.

Resumo

Hibernomas mamários são tumores benignos extremamente raros compostos por gordura marrom, com apenas cinco casos previamente relatados na literatura. Relatamos o caso de uma paciente do sexo feminino, de 42 anos de idade, apresentando-se com uma massa indolor em sua mama direita. Realizou-se uma mastectomia parcial e o diagnóstico de hibernoma mamário foi confirmado pelo padrão morfológico e pelo perfil imuno-histoquímico. Embora hibernomas constituam neoplasias benignas, seus principais diagnósticos diferenciais incluem lesões agressivas, sendo o diagnóstico acurado extremamente importante para o correto manejo clínico do paciente.
