Periosteal Chondroma
Histologically the tumor is very similar to enchondroma, but it more frequently displays features of cell proliferation (high cellularity, nuclear plumpness, and frequent double-nucleated cells). Being somewhat painful and causing…
Multiple Chondromas (Chondromatosis, Ollier’s Disease) Associated Condition: Maffucci’s Syndrome
In Maffucci’s syndrome (very rare), multiple, diffuse chondromas are associated with multiple hemangiomas, cutaneous, subcutaneous, or in the deep soft tissues (not in the bone). Basic imaging is the same…
Simple Bone Cyst (Unicameral Bone Cyst)
Localization: It usually arises in the metaphyses of the long bones, beneath the growth plate, but along with patient growth, the cyst migrates to the diaphysis. The most common location…
Fibrous Dysplasia
Location: Femur (proximal), tibia, craniofacial bones, ribs; then humerus, forearm, pelvis. Same sites in multicentric and polyostotic disease. Frequently more areas in the same long bone, or two to three…

Osteofibrous Dysplasia of Long Bones
Localization: The lesion is almost exclusively localized in the shaft of the tibia, occasionally involving the ipsilateral fibula, too. Exceptionally it is bilateral in tibias and fibulas. Clinical: The symptoms…
Histiocytic Fibroma
Localization: It is generally localized in the metaphysis at first and then displaced toward the diaphysis. It starts intracortically/subperiosteally. Most of the lesions are located around the knee and ankle….
