Metastatic malignant schwannoma of orbit: a case report

A case of metastatic malignant schwannoma of the right orbit is presented here. Although the patient had disseminated disease, it was the eye problems which were striking and most symptomatic.
The orbital lesion was at first thought to be the primary tumour until a history of an excised right wrist mass was probed into and the histology traced.
This report is written as malignant schwannoma is an uncommon tumour. The difficulty in diagnosing malignant schwannoma is mentioned. The importance of diagnosis of an orbital metastatic lesion is also pointed out as this is often misdiagnosed.
