Solitary conjunctival extramedullary plasmacytoma

We describe two patients with different adnexal locations of localized extramedullary plasmacytomas, one under the conjunctiva of the caruncle and the other under the tarsal conjunctiva. In both general physical examination and ancillary tests, including bone marrow aspiration, were normal. Because immunohistochemical studies of the tumor showed no immunoglobulin secretion and electrophoresis and immunoelectrophoresis of the serum and urine were normal, we diagnosed solitary conjunctival extramedullary plasmacytoma in each case.
