Late solitary skeletal metastasis to the patella from retinoblastoma. Journal of the Indian Medical Association. 2008 May; 106(5): 313-4http://imsear.searo.who.int/handle/123456789/98152Isolate metastasis to the patella is rare. A young girl treated with bilateral enucleation for retinoblastoma, reported 9 years later with solitary patellar metastasis. Treatment options for distant metastasis from retinoblastoma are not well defined but include combinations of chemotherapy, radiotherapy and surgery. Late skeletal metastasis from retinoblastoma should be differentiated from second primary bone malignancies, with immunohistochemistry, cytogenetic and electron microscopic features, as the prognosis and management are different.engBone Neoplasms --secondaryChildFemaleHumansNeoplasm MetastasisPatella --pathologyPrognosisRetinoblastoma --pathologySkeletonTime FactorsCase Reports
