An unusual macular lesion simulating a neoplasm.

A 55-year-old woman with reticulum cell sarcoma of the stomach presented with a sudden decrease in vision and acute blood loss anaemia with thrombocytopenia. Superficial retinal haemorrhages were present in both eyes. These haemorrhages were absorbed gradually, yet a large macular mass appeared in the right eye which simulated a neoplasm. This mass disappeared over a period of a few weeks leaving minimal changes in the pigment epithelium and remarkably good visual acuity.
