Osteochondrolipoma of the Mandible

Objective: Lipomas are very common benign tumors located in any part of the body in which fat is normally present, but lipomas containing both osseous and cartilaginous elements are rare. Methods: A case of osteochondrolipoma in a 72-year-old man is reported. The tumor in the mental region was 2×1.5×1.5 cm. Results: After resection of the tumor, there has been no recurrence during the 6-month postoperative follow-up. Histological examination confirmed the definitive diagnosis. Conclusions: Osteochondrolipoma is an extremely unusual lesion that should be kept in mind in the differential diagnosis of soft-tissue tumors.

Parosteal osteochondrolıpoma of the mandıble

Osteochondrolipoma is a rare benign soft tissue neoplasm. It is occasionally considered to be a variant of adipose tissue neoplasm ‘lipoma’ showing multiple differentiation pathways of pluripotent stem cells. As with the lipomas they can be seen at any location and show cartilagenous and osteoid differentiation when located parosteally. We present a case of osteochondrolipoma located at the symphysis of the mandible. To our knowledge, this is the first reported case of an oral osteochondrolipoma associated with parosteal localization.
