Primary angiomatoid fibrous histiocytoma of the mandible with EWSR1-ATF1 fusion in an adult patient: case report and review of literature

Angiomatoid fibrous histiocytoma (AFH) is a rare intermediate malignant tumor that typically occurs in the soft tissues of the extremities in children and young adults. AFH arising in bone is very uncommon, and only seven cases have been reported in the literature. The wide morphologic spectrum and lack of a specific immunophenotype make the diagnosis of AFH challenging when it occurs in uncommon sites. Herein, we present a case of a 42-year-old male who was examined for right mandible pain, and cone beam computerized tomography (CBCT) demonstrated an expansile, lytic lesion of the right mandible with the destruction of cortical bone and invasion into soft tissue.
