Ossifying fibroma
Ossifying fibromas are benign bone lesions that should be differentiated from non-ossifying fibromas and fibrous dysplasia. Osteofibrous dysplasia is considered as a separate pathological entity in view of its different presentation and treatment, although histopathologically similar to ossifyin...
Article
Chondromyxoid fibroma
Chondromyxoid fibromas (CMF) are extremely rare, benign cartilaginous neoplasms that account for <1% of all bone tumors 1.
CMF accounts for one of the 'C's in the popular mnemonic for lucent bone lesions FEGNOMASHIC.

Tendon sheath fibroma
Tendon sheath fibromas are rare proliferative lesions with common imaging features of tenosynovial giant cell tumors.
Epidemiology
They are found in adults typically between the age of 20 and 50 with a 3:1 male predominance 2.
Pathology

Article
Non-ossifying fibroma
Non-ossifying fibromas (NOF) are benign and generally self-limiting osteoclastic giant cell-rich bone tumors typically found in the metaphyses of long bones. They are classified as osteoclastic giant cell-rich bone tumors 1,2.
NOFs account for the 'N' in the popular mnemonic for lucent bone les...
Article
Cemento-ossifying fibroma
Cemento-ossifying fibroma (COF) are rare, benign neoplasms that usually arise from the mandible or maxilla. They most often arise from the tooth bearing areas of these bones.
Terminology
