A patient with a malignant lymphoma of the thyroid with the sarcoid reaction was treated with surgery and radiotherapy and has had no recurrence for about 3 years after surgery.
For the preoperative diagnosis delayed scintigraphy with 201Tl and scintigraphy with 67Ga and fine needle aspiration were quite useful in differentiating thyroid malignant lymphoma from other thyroid tumors.
Treatment should be a combination of surgery and radiotherapy, and chemotherapy should be employed as adjuvant treatment in advanced cases.
The altered immune reaction in the Sarcoid reaction may be considered to be the causative factor in malignant lymphoma.
