Orbital lymphomas (OLs) account for 2% of all lymphomas and only 1% of all non-Hodgkin’s lymphoma (NHL). However, in patients >60 years of age, lymphomas are the most common primary orbital tumor. The majority of cases are primary, low-grade, B-cell, NHL.The most common sub-type is extranodal marginal-zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) type lymphomas. OLs other than MALT lymphoma have different histologies, with diffuse, large, B-cell lymphoma being relatively common. The presentation of OL is variable based on the involved part of the orbit. Accurate diffferentiation of OL from benign lymphoproliferative disorders is crucial due to the differences in management. Imaging characteristics and the clinical findings should be carefully evaluated, and lymphomas should be considered in the differential diagnosis of slowly growing periorbital/orbital region masses in adults. We report an unusual presentation of a primary OL with a rubbery temporal region mass in a 59-year-old woman.
