Abstract
|
|
|
Well-differentiated osteosarcoma is extremely rare, there is no sex predominance and the mean age is in
the third decade. The tumor has a strong predilection for the long bones of the extremities, especially
the metaphysis but may also occur in the diaphysis. Radiologically, the lesion shows no distinctive
features, often simulating fibrous dyplasia or desmoplastic fibroma. We report a case of well-differentiated
osteosarcoma involving the rib of a 45-year-old female. This is a peculiar case of well differentiated
osteosarcoma involving an unusual site and older patient. We also discuss histological differential
diagnosis as well as clinical features of this rare disease.
