Benign approach to a malignant orbital tumor: metastatic renal cell carcinoma.

A well-circumscribed, pseudoencapsulated benign-appearing lesion in the retrobulbar orbit of a 50-year-old man was found to be a metastatic renal cell carcinoma. The patient had a nephrectomy for renal cell carcinoma 15 years before, and had developed four other isolated metastases over the preceding 8 years. He had a further distant metastasis 1 year later, but is living and well 4 years after excision of the orbital tumor. Metastatic renal cell carcinoma of the orbit may have very benign characteristics, both clinically and radiographically, and can often be managed effectively by local excision with prolonged survival.

Amyloidosis of the vitreous. Fluorescein angiographic findings and association with neovascularization.

A case of primary systemic amyloidosis with bilateral asymmetric involvement of the vitreous was followed up throughout a 45-month span, during which two vitrectomy procedures were done on one eye. The progressive nature of this disease was documented by serial fluorescein angiograms and fundus photography. The amyloid seemed to be derived from the retina, at small multifocal areas over arterioles and venules that were otherwise clinically and angiographically normal in appearance. Follow-up studies suggested that these focal deposits were actually preretinal, since they disappeared after posterior vitrectomy. Peripheral neovascularization was visible in this case, which has not previously been reported. Amyloidosis of the vitreous can mimic numerous other diseases. Vitrectomy can be effective in restoring visual acuity, although recurrence may be rapid. The diagnosis is readily made by pathologic examination of the vitreous aspirate.
