Intraconal plasmocytoma and uveal infiltration in a patient with multiple myeloma

Abstract Multiple myeloma (MM) leads to disorderly proliferation of plasma cells clones, producing monoclonal immunoglobulin and commonly presents osteolytic lesions. In some cases, however, masses called plasmocytomas are found. Ocular and orbital involvement is unusual in this pathology. In this paper, we describe a case of a 63 year-old patient with previous diagnostic of MM that evolved an intraconal plasmocytoma in the right eye, as well as a vascularized mass in the anterior chamber from uveal infiltration. These lesions were correlated to MM e lead to visual loss in the affected eye. Reports of intraconal plasmocytoma have not been found in literature.
