RESUMEN
Our 69-year-old female patient was investigated for a 20 kg weight gain over 2 years. The patient's medical history included hypertension, hyperuricemia, bilateral cataract surgery and musculosceletal complaints. Diabetes mellitus was not found. Physical examination revealed abdominal obesity, proximal myopathy and atrophic, vulnerable skin. The "overnight", low-dose and long, low-dose dexamethasone suppression tests indicated autonomous cortisol overproduction (plasma cortisol level: 172.6 and 153.2 nmol/L, cut-off: 50 nmol/L). The suppressed ACTH (<1.11 pmol/L, normal value: 1.12-10.75 pmol/L) suggested ACTH-independent hypercortisolism. Abdominal CT described macronodular enlargement of both adrenals. The size of the largest nodule was 23 × 20 mm in the right, and 24 × 30 mm on the left side (with -33 ± 37 HU density values on native scans). The 131I-cholesterol adrenal scintigraphy and SPECT/CT showed almost equally intensive radiopharmacon uptake on both sides. Based on the clinical results, bilateral macronodular adrenal hyperplasia associated with ACTH-independent hypercortisolism was diagnosed. Genomic DNA was obtained from the peripheral blood leukocytes. Targeted sequencing of 25 genes potentially involved in adrenal tumorigenesis revealed a new disease-causing armadillo repeat-containing 5 (ARMC5) gene mutation (c.1724del28 bp, g.31,476,067-31,476,094). Because of the autosomal dominant inheritance of this genetic alteration, the patient's two children underwent genetic screening for the ARMC5 mutation. The same mutation was found in the younger child of our patient. To the best of our knowledge, this is the first published Hungarian case of ARMC5 mutation with bilateral macronodular adrenal hyperplasia and ACTH-independent Cushing's syndrome. The genetic alteration is present in two generations of the family of the index patient. Orv Hetil. 2023; 164(32): 1271-1277.

Introduction: According to the recommendation of the American Thyroid Association 2015 guideline, the treatment of 1-4 cm (T1b-2) low-risk differentiated thyroid cancer (DTC) is lobectomy without radioiodine therapy. Objective: Retrospective analysis of multifocality in surgical and histological data of T1-2 patients living on moderate iodine intake. Methods: Analysis of the pathological characterisation of 81 low-risk (T1-2) DTC patients who underwent total thy-roidectomy. Patients were treated at Flor Ferenc Hospital, Kistarcsa, Hungary, between 2013 and 2019. Results: 64 patients had T1, while 17 patients had T2 status. 65/81 (80.2%) patients had papillary, and 16/81 (19.8%) had follicular subtype. Lymph node metastasis was detected up to 18.4% in papillary and 18% in follicular patients. Multifocal tumours were detected in 25% (16/64) of T1 patients, of these 10.9% (7/64) was unilateral and 14.1% (9/64) was bilateral. Multifocal tumours were detected in 11.7% (2/17) of T2 patients; both were bilateral. Distribution of T1-2 bilateral multifocal patients (11/81; 13.5%) was n = 3 T1a-, n = 6 T1b and n = 2 T2 stadium, from these 10 patients received radioiodine treatment. The sizes of contralateral tumours were <5 mm in 9 patients, and >5 mm in 2 patients. Conclusions: Due to the frequent (13.5%) bilateral multifocality in T1-2 DTC patients, we suggest total thyroidec-tomy instead of lobectomy. After lobectomy, the follow-up of the contralateral tumours is almost impossible by ul-trasonography due to the small tumour size (on average 2.8 mm) and frequently detected benign nodules; therefore the multifocality might remain undetected, which can distort the plan for adjuvant treatment.

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.
