Abstract
Primary malignant lymphoma of the thyroid gland is not a rare disease that we come across in our hospital. Here we report a rare case of adenomatous goiter infiltrated by malignant lymphoma. A 42-year-old woman was admitted to our hospital because of slow-growing anterior neck tumor and rapid-growing axillary tumor. The right anterior neck tumor was 12 cm in diameter and the right axillary tumor was 7 cm in diameter. Fine needle aspiration cytology revealed that these two tumors were class V and malignant lymphoma was suspected. We performed an open biopsy of the neck tumor and histopathological examination revealed that diffuse large B-cell lymphoma co-existed with adenomatous goiter. Eight courses of CHOP were conducted for the patient and CR was ob-tained in her axillary tumor but her neck tumor was NC. We performed surgical resection of the neck tumor and histopathological examination revealed the pathological CR of malignant lymphoma.
