Resumen

Background and objective: Plasmacytomas are localized collections of monoclonal plasma cells. Patient and method: This is a 48-year-old female patient of mixed race, with no significant medical history, with a soft, painless tumor adhered to the sclera, in the bulbar conjunctiva and inferior temporal fornix. The method used was the presentation of a clinical case. Results: The tumor was excised with pathological analysis and immunohistochemical study confirming the diagnosis of conjunctival plasmacytoma. Postoperative follow-up was uneventful. Conclusions: Extraosseous plasma cell tumors located in the eye are rare and difficult to diagnose because they present a wide range of clinical differentiation.
