All the following are differential diagnoses for tumors of the bone except:
|B||Traumatic nerve injury|
Traumatic nerve injury
a. A large clotted subperiosteal hematoma or soft tissue hematoma may present as a painful lump in the arm or lower limb.
b. Osteomyelitis typically causes pain and swelling near one of the joints and as with primary bone tumors the patients are usually children or young adults.
c. Myositis also can be a source of confusion, following an injury the patient develops a tender swelling in the vicinity of the joint, unlike a malignant tumor however the condition soon becomes less painful and the new bone better demarcated and better defined.
d. Occasionally a large Gouty tophus causes a painful swelling at one of the bone ends, X-ray shows a large poorly defined excavation. Diagnosis can be confirmed by biopsy
