Recurrent Extranodal Marginal Zone B-Cell Lymphoma Presenting as a Huge Cheek Mass after Radiotherapy on Ocular Adnexal Lymphoma / 대한이비인후과학회지

ABSTRACT

Extranodal marginal zone B-cell lymphoma of mucosa associated lymphoid tissue (MALT lymphoma) is a low-grade B-cell lymphoma that presents with an indolent clinicopathologic nature. Although this tumor can occur in various sites, including the gastrointestinal, skin, salivary gland and ocular adnexa, radiation therapy shows high local control in that disease. We report a case of recurrent MALT lymphoma presenting a huge cheek mass after radiotherapy on ocular adnexal lymphomas. An 65-year-old man had a history of treatments on MALT lymphomas of ocular adnexa came again with a huge cheek mass, not recurred and not originated from salivary gland, skin, other related mucosa tissues. He got excisional biopsy and was confirmed immunohistochemically as MALT lymphoma. After diagnosis, he was sent urgently to a radiotherapist for further treatment. He responded well to added radiotherapy with 36 Gy dose and has remained well at 6 months after his initial presentation.
