Primary extraosseous cemento-ossifying fibroma of the auricle

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.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
