INTRAOSSEOUS LIPOMA: A CASE REPORT

Abstract

A 67-year-old male patient was referred to the oral medicine service to evaluate an asymptomatic mandibular radiolucency observed in the panoramic radiograph. The lesion had at least 3 years of evolution. The extraoral and intraoral examinations revealed no alterations. The cone-beam tomography revealed a 25mm x 30mm hypodense circular image, presenting discrete lobulations. An incisional biopsy under local anesthesia was performed. The diagnostic hypotheses were keratocyst, ameloblastoma, or aneurysmal bone cyst. During the surgical procedure, a soft yellowish tissue resembling adipose tissue was observed. After excisional biopsy, the specimen was submitted to a histopathological analysis. The presence of lobules of mature adipose tissue surrounded by a fibrous capsule led to a final diagnosis of intraosseous lipoma. After 3 months of follow up, no recurrence was observed.
