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.
