We report an uncommon case of a 20-year-old man, who noted a painless, growing mass in his neck, which appeared in a weekend, associated with moderate dysphagia and weakness. Laboratory examination revealed an elevated serum thyrotropin of 25 mU/L, normal serum triiodothyronine and thyroxine levels, and high titers of antithyroglobulin and antithyroid peroxidase antibodies. The neck lesion showed a depressed iodine uptake in the left thyroid lobe, which had an asymmetrical pseudocystic pattern associated with poor vascularization in the ultrasound scan. Cytologic examination showed a lymphocyte thyroiditis in association with lymphoma of large cell arising from mucosa-associated lymphoid tissue (MALT-lymphoma or maltoma). The patient underwent a left thyroid lobectomy while being treated with levothyroxine for Hashimoto's thyroiditis, and the surgical treatment was further complemented with chemotherapy using fludarabine. The histologic examination confirmed the cytologic findings and the immunohistochemistry showed a B-cell type maltoma. Additional investigation provided no evidence of disease in other tissues. The clinical course has been favorable in the first 2 years of follow-up, with no evidence of local or systemic recurrence of the disease.

Impaired muscle function may be a predominant aspect of hypothyroidism and is virtually present in all patients with overt thyroid failure. Less common is the onset of hypothyroidism with clinical features mimicking a polymyositis. We have observed 3 patients, whose age ranged 63-68 years, presenting with muscle aches, cramps, proximal weakness and stiffness. Two patients had dysphagia. Serum creatine kinase (CK) and electromyography (EMC) were altered in two patients. Muscle biopsy showed type II atrophy, sporadic type I and type II grouping, "core-like" areas, and some myopathic changes such as central nuclei and muscle necrosis. No inflammatory changes were present. Immunohistochemistry of several muscle cytoskeletal proteins revealed increased desmin in "corelike" areas. Detection of serum thyroid hormone levels revealed very low triiodo-L-thyronine (T3) and thyroxine (T4), whereas thyroid-stimulating hormone (TSH) was greatly increased as well as serum anti-thyroglobulin, anti-peroxidase and anti-microsome antibodies. The patients were diagnosed having a hypothyroid myopathy due to Hashimoto thyroiditis. L-thyroxine treatment normalized clinical and hormone levels, but serum antibodies remained elevated. Muscle biopsy was fundamental to establish the correct diagnosis in our patients. Presence of over-expression of desmin in cores, as described in target lesions in neurogenic diseases, may suggest a nerve-mediated pathogenesis of hypothyroid myopathy.

65 years old male patient received 4 mg/day methylprednisolone baseline therapy and 50 mg/week etanercept treatment for 5 years due to rheumatoid arthritis. The patient experienced pain in neck, and developed weakness, fever and dysphagia. He had normal blood count but accelerated erythrocyte sedimentation rate (88 mm/hour), elevated CRP (49.3 mg/l) and hyperthyroidism (TSH 0.006 mIU/l, fT4 27.22 pmol/l, fT3 5.61 pmol/l). The autoimmune origin could be excluded because of normal values of antibodies against thyreoidea peroxidase and TSH receptor. The ultrasound investigation showed focal hypoechogenic structure and low vascularisation. Based on the laboratory and ultrasound results as well as clinical signs etanercept related subacute thyroiditis was supposed. As part of the treatment we interrupted the etanercept treatment and gave 16 mg methylprednisolone for 5 days, then 8 mg for 7 days, after that the patient received the daily 4 mg of methylprednisolone as baseline therapy. After rapid improvement the symptoms got worse again so we repeated the administration of methylprednisolone treatment with a higher dose (16 mg/day for 5 days then 8 mg/day for two months). Thyroid functions and the inflammatory markers got normalized. We conclude the necessity of monitoring the thyroid function during etanercept treatment thus avoiding this rare but serious side effect. Orv Hetil. 2017; 158(39): 1550-1554.
