Head and neck osteolipoma: A case series study and review of literature

Osteolipoma is a rare variant of lipoma that can arise mainly in the lower limbs and the head and neck region. As of January 2023, 51 cases of head and neck osteolipomas have been described in the English literature, excluding the tuber cinereum osteolipomas. The review was performed using the Pubmed and Scopus search engines and the following keywords: [osteolipoma], [ossifying AND lipoma] or [lipoma AND osseous metaplasia]. In addition to these 51 cases, we present 3 more cases of osteolipomas involving the craniomaxillofacial area. The scope of this study is to broaden the knowledge regarding this rare tumor and improve the treatment and follow-up protocols.
