Extramedullary pasmacytoma masquerading as chalazion

Extramedullary plasmacytoma (EMP) is a rare entity that belongs to the category of non-Hodgkin lymphoma. EMP make up 4% of all plasma cell tumors and occur mainly in the upper aerodigestive tract. Primary plasmacytoma involving the orbit is rare. There is a relation between solitary plasmacytoma and subsequent development of multiple myeloma. As no predictors of progression have been identified patients need indefinite follow-up. The authors report a case of EMP involving the eyelid in an otherwise healthy adult female.
