Extramedullary plasmacytoma confined to the choroid.
OBJECTIVE
To report a case of an extramedullary plasmacytoma confined to the choroid.


METHODS
Interventional case report with cytopathologic correlation.


RESULTS
A 76-year-old asymptomatic woman presented with 2 globular orange and amelanotic choroidal lesions in the right eye. Fine needle aspiration biopsy of one of the choroidal lesions followed by immunocytochemical studies revealed monoclonal plasma cells, diagnostic of plasmacytoma. Systemic evaluation was negative, except for increased serum gamma globulin with immunoglobulin kappa spike on electrophoresis. The patient was managed by ocular external beam radiotherapy. At 9 years follow-up, she was free of local disease and never developed multiple myeloma.


CONCLUSIONS
Extramedullary plasmacytoma confined to the choroid is rare. It may present simulating other common amelanotic choroidal lesions. Fine needle aspiration biopsy and proper systemic evaluation are critical in establishing the diagnosis.
