An unusual ophthalmic tumour in a 5-year-old boy.

A rare tumour in a 5-year-old boy is presented and discussed. In time and location the story had two parts (Fig. 1): 1) a conjunctival granuloma at the nasal limbus of the right eye was surgically removed. 2) a few months later a huge lesion presented in the posterior segment of the same eye. Was it an ocular tumour with extension to the orbit or an orbital process with impression or invasion of the eye? Repeated surgical biopsies have indicated nodular scleritis of the posterior eye segment as the definitive diagnosis.
