[Primary lymphoma of the thyroid: a case report].

Primary lymphoma of the thyroid is an uncommon disease. It diagnosis is difficult without immunohistochemestry. We report a case of thyroid lymphoma diagnosed at the A. Le Dantec Hospital of Dakar. A 22-year old young man presented anterior neck mass. Clinical examination showed a thyroid mass with a susclavicular palpable lymph node. The scintigraphy demonstrated that the mass was cold. Total thyroidectomy with cervical lymphadenectomy was the first treatment. Histological examination of the surgical specimen concluded that the mass was an anaplastic lymphoma (large cells type) involving the sus clavicular lymph nodes (stage IIE). Chemotherapy was administrated after one month with C-MOPP schedule. The patient presented no recurrent sign after 30 month. Fine needle aspiration and immunocytochemestry of the thyroid cold masses will contribute in an accurate diagnosis and the management of disease in our institution.
