Abstract
MALT lymphomas of the orbit are rare orbital tumors; the differential diagnosis needs to exclude inflammatory pseudotumors of the orbit, but also benign lymphoproliferations, pseudolymphomas, and other orbital neoplasms. After histological confirmation of the diagnosis staging is necessary, and - as long as the disease is localized exclusively in the orbit - radiation therapy should be started. The clinical picture of MALT lymphoma and its differential diagnosis and treatment are discussed with reference to an actual case.
