Ewing's sarcoma as second malignant neoplasm after retinoblastoma: a case report.Mittal R, Al Awadi S, Sahar O, Behbehani AM Department of Medical Oncology, Hussain Maki Al Juma Centre for Specialized Surgeries, Kuwait. rakeshmittal55@hotmail.com OBJECTIVES: To report a case of a child with the hereditary form of unilateral retinoblastoma (RB), who developed Ewing's sarcoma of the right fibula 3 years after the enucleation of the right eye. CASE PRESENTATION AND INTERVENTION: The child was diagnosed as a case of RB of the right eye at the age of 9 months. He was fully investigated and found to have locally advanced RB with bone marrow involvement (Reese-Ellsworth stage IVA). Enucleation was recommended to the family, but they refused. The patient received chemotherapy and diode laser thermotherapy in Kuwait and the UK. He had a local relapse after 11 months and subsequently underwent enucleation of the right eye. After 3 years, he was investigated for a small swelling in his right lower leg. After extensive investigations, it was reported as Ewing's sarcoma. He was treated with chemotherapy, surgery (complete excision of the fibula) and high-dose chemotherapy followed by autologous stem cell transplantation. The child is now nearly 2 years after completing the treatment and is disease free. CONCLUSIONS: This case confirms the increased risk of a second malignant neoplasm (SMN) in children with hereditary RB. These children need a very close follow-up for the early diagnosis of SMNs or even subsequent malignancies. Published 6 December 2007 in Med Princ Pract, 17(1): 84-5.
