Abstract

Most of nasal cavity or paranasal sinuses lymphoma reported in Korea is either diffuse large Bcell lymphoma or natural killer/T-cell lymphoma. There are only three cases of mucosa-associated lymphoid tissue lymphoma (MALTOMA), which has so far been reported only in a Korea journal and all of which have occurred in the nasal cavity and in the turbinate. We experienced a case of MALTOMA of ethmoid sinus extending to the orbital cavity. It was confirmed by the findings of immunohistochemical staining (positive with CD20, Bcl-2, and Granzyme B, negative with CD5, CD56, Bcl-6 and Cyclin D1). The patient underwent radiation therapy and the lesion was successfully resolved without recurrence for 16 months.
