Treatment of a patient with adnexal lymphoma with Rituximab.

Orbital lymphoma is a very rare type of primary Non-Hodgkin lymphoma. The disorder is often small B-cell lymphoma, although large cell morphology may also be identified in rare cases. It may sometimes be confused with non-malignant, benign-course lymphoid hyperplasia. Although involvement is usually unilateral (80%), bilateral cases are also reported. Response to radiotherapy is achieved in the majority of cases, whereas the prognosis is poor in orbital involvement with large cell lymphoma and response to combined chemotherapy is inadequate. In this paper, we report a case with a diagnosis of unilateral adnexal involvement, who previously received CHOP treatment and developed a relapse 6 months later, then responded to treatment with Rituximab.
