✦ Synopsis

Background. A mass of the auricle is uncommon. An enlarging lesion may be the result of a reactive process, or a benign or malignant neoplasm. The literature is reviewed, and a case of extraosseous cemento-ossifying fibroma of the auricle is presented.

Methods. A 22-year-old white man presented with a 3-month history of an enlarging 2 cm mass in the right concha cavum. An incisional biopsy demonstrated cemento-ossifying fibroma. The lesion was resected en bloc, and the patient did well. There is no evidence of recurrence.

Results. Pathological examination of the excised mass revealed a well-circumscribed but unencapsulated spindle cell lesion with foci of osteoid and cementum deposition. It did not involve the auricular cartilage, and there was no connection with the overlying epidermis.

Conclusions. This is a case report of an extraosseous cemento-ossifying fibroma of the auricle. This benign tumor should be completely excised because local recurrence may otherwise result.
