Patients with Hodgkin's disease have higher a prevalence of thyroid function abnormalities and, perhaps, orbitopathy than the general population, but the pathophysiology of this association and its relationship to Hodgkin's disease treatment remain unclear. We analyzed the frequency of thyroid function abnormalities, autoantibodies against thyroid antigens, and autoimmunity against extraocular muscle cell antigens by Western blot analyses and antibody-dependent cellular cytotoxicity (ADCC) assays in patients with Hodgkin's disease (n = 20) and controls (n = 10). Hodgkin's disease patients were subdivided into those treated with thyroidal external beam radiation therapy (XRT, n = 15) or chemotherapy (MOPP/ABVD, n = 5). The ADCC assay against extraocular muscle cells was increased in patients with Hodgkin's disease (5.5% vs. <1.0%, p = .026) when compared with controls. In addition, Hodgkin's disease patients treated with XRT (with or without chemotherapy) had significantly higher ADCC tests than controls (9.7% vs. <1.0%, p = .010), In contrast, ADCC assays were not different between Hodgkin's disease patients treated with chemotherapy alone and controls (<1.0% vs. <1.0%, p = .53). Hodgkin's patients treated with XRT had higher ADCC assays than those treated with chemotherapy alone (p = .087), although this difference did not achieve statistical significance. Serum measurements of antithyroid peroxidase (TPO) antibodies, antithyroglobulin (Tg) antibodies, thyroid binding inhibitory immunoglobulins (TBII), and thyroid stimulating immunoglobulin (TSI) were similar in all groups. Antibodies against the 64 kDa orbital antigen were detected in 1 patient and 1 control subject. Excluding patients already treated with L-thyroxine for hypothyroidism (n = 5), free T3, but not free T4, was lower in the Hodgkin's disease group than in controls (2.2 pg/mL vs. 2.7 pg/mL, p = .008). Thyrotropin (TSH) concentrations were not statistically different between these groups. In summary, these data show: (1) ADCC against human orbital muscle cells is increased in patients with Hodgkin's disease compared with controls: (2) these differences were noted among Hodgkin's disease patients treated with thyroidal XRT, with or without chemotherapy, and not among those patients treated with chemotherapy alone; and (3) no statistically significant differences in the frequency of thyroid autoantibodies were found. These data suggest that patients with Hodgkin's disease display altered antibody-dependent immune function toward extraocular muscle cells that may possibly be related to by XRT. Larger, prospective studies assessing thyroid and orbital-related immunologic abnormalities in Hodgkin's disease are warranted.

A 27-year-old woman was first referred at the age of 14 with cosmetic complaints due to an echographically diffuse, euthyroid goitre. Tests for antibodies against thyroid peroxidase and thyroglobulin were positive. Thyroid-suppression therapy with levothyroxine resulted in regression of the goitre. At the age of 26 there was a transitory recurrence of the goitre during a pregnancy, during which time the thyroid peroxidase antibodies became strongly positive. Six months post partum the goitre recurred again, accompanied by pain in the throat and fever. The C-reactive protein level was strongly elevated. Serology established the diagnosis of viral thyroiditis due to a Coxsackie-B virus. The size of the goitre decreased after treatment with acetylsalicylic acid and prednisone. Two months later the goitre again showed further growth, now in association with cervical lymphadenopathy and an enlarged left parotid gland. Histology revealed a non-Hodgkin lymphoma of the type diffuse large B-cell (stage II), very likely a primary thyroid lymphoma. The lymphoma was refractory to cyclophosphamide-doxorubicin-vincristine-prednisolone (CHOP); this was followed by intensive chemotherapy and autologous stem-cell transplantation, resulting finally in a complete remission. The goitre disappeared and thyroid peroxidase antibodies were no longer detectable. Primary thyroid lymphoma is a rare disease, but autoimmune thyroiditis appears to be an important predisposing factor.

The aim of this study is to present a case of a 36-year old male with a rare thyroid malignancy--a primary thyroid lymphoma. The patient was admitted to the Department of Endocrinology due to a rapidly enlarging left-sided tumor of the neck and hoarseness lasting for 2 weeks. The only abnormality found on biochemical testing was a slightly elevated titre of anti-TPO antibodies. On X-ray examination, both a compression and deviation of the trachea was found. Ultrasound examination of the neck revealed a left-sided thyroid lesion and fine needle aspiration (FNA) was performed under ultrasound guidance. A monotonous population of mid-size lymphoid cells was found with negative immunocytochemistry for thyroglobuline and CD 68. After hematological and pathological evaluation the FNA report was considered as non-diagnostic. Taking into consideration the presence of rapidly occurring compressive symptoms caused by a tumor of unknown cytological origin, the patient was referred to urgent thyroid surgery. Pathological report of postoperative specimen allowed for the final diagnosis of a malignant lymphoma originating from non-Hodgkin B cells of the thyroid gland; diffuse large B-cell lymphoma (DLCL) according to WHO classification. L-thyroxin substitution therapy, chemo- and radiotherapy were used after the operation. The described case of a very rare type of primary thyroid malignancy illustrates difficulties which can be encountered in diagnostic approach and therapeutic decision making in patients with rapidly enlarging thyroid tumors.
