Typically, there are no symptoms unless there is a fracture. [2] It can occur as part of a syndrome such as when multiple non-ossifying fibromas occur in neurofibromatosis, or Jaffe–Campanacci syndrome in combination with cafe-au-lait spots, intellectual disabilities, hypogonadism, eye and cardiovascular abnormalities.

The most common bone tumor is a non-ossifying fibroma. [4] Average five-year survival in the United States after being diagnosed with bone and joint cancer is 67%. [ 5 ] The earliest known bone tumor was an osteosarcoma in a foot bone discovered in South Africa, between 1.6 and 1.8 million years ago.
High magnification micrograph of giant cells in a giant-cell tumor of bone, H&E stain. The diagnosis of giant-cell tumors is based on biopsy findings. The key histomorphologic feature is, as the name of the entity suggests, (multinucleated) giant cells with up to a hundred nuclei that have prominent nucleoli.
The cystic fibroma (fibroma cysticum) has central softening or dilated lymphatic vessels. The myxofibroma (fibroma myxomatodes) is produced by liquefaction of the underlying soft tissue. The cemento-ossifying fibroma is hard and fibrous, most frequently seen in the jaw or mouth, sometimes in connection with a fracture or another type of injury.
Osteofibrous dysplasia is a rare, benign non-neoplastic condition with no known cause. It is considered a fibrovascular defect. Campanacci described this condition in two leg bones, the tibia and fibula, [1] and coined the term. This condition should be differentiated from nonossifying fibroma and fibrous dysplasia of bone.
Furthermore, autoimmune pain is typically described as morning stiffness whereas osteoarthritic pain is usually described as end-of-day soreness. [8] There are many potential rare and uncommon causes of a non-specific symptom like elbow pain. If associated with weight loss, bone pain, or an enlarging mass there is concern for a bone tumor.
Some of the most common symptoms are a hard immobile painless palpable mass, adjacent muscle soreness, and pressure or irritation with heavy exercising. [5] Major symptoms arise when complications such as fractures, bone deformity or mechanical joint problems occur. If the occurrence of an osteochondroma is near a nerve or a blood vessel, the ...
Patients typically present with swelling with or without pain. The slow-growing tumor predominantly arises in long bones in a subcortical location (95% in the tibia or fibula). [3] Benign osteofibrous dysplasia may be a precursor of adamantinoma [4] [7] or a regressive phase of adamantinoma. [8]
