Metastatic retinoblastoma presenting as abdominal mass

Abstract

A 5-year-old girl was diagnosed as a case of retinoblastoma in the left eye and enucleation was done. There was recurrence of the tumour in the orbit for which radiotherapy was given; and the tumour resolved completely. Fifteen months after the completion of radiotherapy, she presented with abdominal mass. The mass was removed from retro uterine space by laparotomy; and the biopsy report was consistent with retinoblastoma. After comparing with the histological findings of the enucleated eyeball slide, it was confirmed as metastatic retinoblastoma in the retro uterine space. She was given chemotherapy since there was slight widening of mediastinum and mild pleural effusion on the right side, which subsided after chemotherapy. This case is reported in view of rare occurrence of secondary in the abdomen in a child with retinoblastoma.
