title: A huge osteolipoma involving the coronoid process: a case report.
abstract: A 28-year-old man visited our hospital with the chief complaint of trismus. Computed tomography revealed a well-defined, soft tissue tumor, 66 × 45 × 21 mm, with a distinct boundary in the inner region of the zygomatic arch. The mass contained various sizes of bone-like hard tissue, some of which adhered to the right coronoid process. A contrast-enhanced magnetic resonance image showed that the mass was composed mainly of adipose tissue. Tumorectomy was performed, and the histopathological diagnosis was osteolipoma. At 2-year follow-up, mouth opening had increased from 31 mm to 50 mm. (J Oral Sci 58, 141-144, 2016).
