Calcifying aponeurotic fibroma (CAF) is an uncommon benign soft-tissue fibroblastic tumor with characteristic histological features. It mainly occurs in the distal part of the extremities, such as the hands and feet, in children and adolescents. Males are twice as commonly affected as females. CAF exhibits local invasiveness, and hence, its recurrence rate is also high. Therefore, complete surgical excision is both diagnostic and therapeutic. The occurrence of CAF in the maxillofacial region, especially the temporomandibular joint (TMJ), is very rare, and this necessitates its differentiation from other TMJ neoplasms. The differential diagnosis of CAF requires microscopic examination. Herein, we report a rare case of CAF located at the left mandibular condyle, which was confirmed by histopathological analysis.
