Description
Summary:A case of postpartum silent thyroiditis simulating a malignant lymphoma of the thyroid is reported. The patient was a 30-yr-old female who had received irradiation thearapy to the neck for malignant lymphoma of the thyroid 9 yr previously. She was referred to our department because of a struma associated with acute aggravation of chronic thyroiditis after parturition. In this case, the mechanism of the disease was explained by the "immune rebound hypothesis". It was difficult to differentiate postpartum silent thyroiditis from malignant lymphoma of the thyroid, either clinically or cytologically, when the immune-rebound phenomenon with lymphocytic infiltration and the appearance of lymphoid follicles were prominent. The immunological status of patients with chronic thyroiditis accompanied by morphological changes should be taken into consideration before establishing the diagnosis of malignant lymphoma of the thyroid.[PUBLICATION ABSTRACT]
