The Management of an Orbital Diffuse Large B-Cell Lymphoma

Background The orbit represents a rare site of presentation of non–Hodgkin lymphoma. The diagnosis and management of orbital lymphomas may be challenging because these neoplasms present few specific features. Methods A 69-year-old woman presented with painless swelling of the left lower eyelid of 5 years’ duration. Magnetic resonance imaging and incisional biopsy were necessary to establish a diagnosis of orbital diffuse large B-cell lymphoma. Staging was completed, thanks to a computed tomographic study of the chest and abdomen. Results The patient underwent systemic chemotherapy with 1 regimen (doxorubicin, vincristine, prednisone, 6-mercaptopurine, and methotrexate), followed by 1 R-COMP-14 regimen (rituximab, cyclophosphamide, nonpegylated liposome–encapsulated doxorubicin, vincristine, and prednisone). Complete resolution of the disease was obtained. Conclusions Although not typically performed by the head and neck surgeon, an understanding of the staging process is crucial for multidisciplinary management of orbital lymphomas.
