CHONDROLIPOMA IN AN UNCOMMON LOCATION: CASE REPORT

Chondrolipoma is a benign mesenchymal tumor that may occur anywhere in the body, such as soft tissues of the skeletal system, but is rarely seen in oral cavity. This lesion is a rare histologic variant of the lipoma with uncertain pathogenesis. A 68-year-old woman presented a nodule that was sessile, erythematous, and measured 1 cm in the region of the middle line in the upper alveolar ridge with complaint of painful symptomatology and bleeding, associated with the use of poorly adapted upper prosthesis. Excisional biopsy was performed and histopathologic examination revealed a proliferation of mature adipocytes interspersed with myxoid connective tissue with focus of cartilaginous tissue, being conclusive as a chondrolipoma. The histopathologic diagnosis of chondrolipoma is determinant, especially in a lesion in an unusual location. The treatment of choice for these tumors consists of surgical excision. The patient is under follow-up with no recurrence of the lesion during a 1-year follow-up period.
