Osteomas are benign tumors composed of mature compact or cancellous bone. Osteomas of the jaws may arise on the surface of the bone, as a polypoid or sessile mass which can be classified as central or peripheral. Extraskeletal lesions of soft tissue, typically located within muscle or the dermis of the skin (osteoma cutis), also are possible. The most common gnathic locations are the body of the mandible or the condyle. When located in the body, most osteomas occur posterior to the premolars on the lingual surface. Less common mandibular locations include the angle (particularly at the inferior border), coronoid process, and ramus. (Neville, 2024) A 57-year-old Hispanic female, in good health with history of controlled hypertension, uneventful cesarean section and not reporting history of smoking, or substance abuse, who presented to the University of Puerto Rico (UPR) Oral and Maxillofacial Surgery (OMFS) outpatient clinic, with a chief complaint of: "I want this excess bone removed". The patient stated that she has had this tumor to the right side of the mandible since she was 27 years old. The lesion was asymptomatic and of very large size. She denies any pain or numbness. The patient attempted to have it removed at another institution, but the surgery was canceled due to administrative reasons. Her children encouraged her to seek professional help and have it removed. Upon physical examination, extraoral fullness of the right cheek was noted. Intraorally, a firm non-mobile mass, with bony consistency and covered by smooth regular pink colored mucosa was palpated. This mass was projecting outward from the body of the mandible, distal to tooth #29 and into the mucosa of the right cheek (Figs. 1, 2, 3). The area was dentate and showing no evidence of previous trauma. *Photos to be submitted.
