RESUMO
Primary thyroid lymphoma is a rare clinical entity, which does not exceed 5% of the diagnosed lymphomas, occur more frequently in women than in men, with a peak incidence in the sixth decade of life. The relationship with chronic thyroiditis is well known. The Hodgkin subtype even rarer; little described in the literature; Posing a diagnostic problem. Diagnostic confirmation is usually carried out on the surgical specimen. To better understand this entity, we report the case of a 64-year-old patient, with no notion of chronic thyroiditis, admitted for Hodgkin's lymphoma of the thyroid, diagnosed on an anterior cervical mass. Thyroidectomy with histopathological and immunohistochemical studies confirmed the diagnosis. The patient had received chemotherapy type ABVD (Adriblastin-Bleomycin-Vinblastine-Dacarbazine) and programmed for radiotherapy.
