Solitary Orbital Plasmocytoma: A Case Report and Review of Literature

Abstract

Solitary orbital plasma cell neoplasm in the absence of multiple myeloma is very rare. We present here a case report of extramedullary plasmacytoma of the left orbital soft tissue in a 50-year-old woman whose thorough diagnostic workup was negative for multiple myeloma. The patient presented with rapidly increasing proptosis, swelling, and visual disturbances of the left eye for past 15 days. MRI of the orbit revealed an extra conal well-circumscribed homogeneously enhancing masse filling the superior and the temporal part of the left orbit without bone destruction Or intracranial extension. The patient underwent a subtotal resection and the pathological report revealed a plasma cell neoplasm. So, normal skeletal survey, absence of bone marrow involvement, absence of Bence-Jones protein, no anemia, no hypercalcemia, no renal disease, normal level of immunoglobulin’s all exclude the diagnosis of multiple myeloma. Since the visual acuity of the patient is well-preserved, so we have planned to treat her with local radiotherapy alone with 50 Gy.
