Abstract
-
Retinoblastoma is one of the primary malignant tumors which rarely undergo spontaneous regression. Survival rate from retinoblastoma is in excess of 90%, but the subsequent development of second tumor is an important factor of the long-term prognosis. The authors experienced a case of osteosarcoma developed on left distal femur in a patient of bilateral retinoblastoma which underwent spontaneous regression.
