ACTA ENDOCRINOLOGICA (BUC)

Context. Patients with renal malignancies present high risk of adrenal hyperplasia and adenoma, and part of these are primary lesions, mostly non-functional. Here we presented a case diagnosed as primary adrenal adenoma with autonomous cortisol secretion accompanied by homolateral renal cell carcinoma. Case presentation. A 79-year-old woman was referred for evaluation of a left adrenal mass, with a past medical history of severe hypertension, diabetes, and hyperlipidemia. On examination, no clinical signs of cushingoid features were found. Biochemical measurements showed plasma cortisol was 12.77 μg/dL and was not suppressed by 1 mg dexamethasone (DXM) overnight test (13.6 μg/dL). The contrast CT scan presented a 2.2 cm diameter adrenal mass and revealed, unfortunately, a hyperdense mass at the middle-upper pole of the left kidney. Laparoscopic nephrectomy with left adrenalectomy was performed and pathological examination indicated a final diagnosis of benign adrenocortical adenoma and renal clear cell carcinoma. At 2 months postoperatively, without replacement treatment of cortisol, a recovery of circadian rhythm of cortisol secretion was detected, indicated recovery of the hypothalamic-pituitary-adrenal axis. Conclusions. Patients with renal cancer might be accompanied with functional adrenal adenoma. Therefore, screening for adrenal function should be recommended in patients with renal tumors and/or adrenal incidentaloma.

Background. Acromegaly is an acquired disorder related to excessive production of growth hormone (GH) and insulin-like growth factor-1 (IGF-1). Empty sella (ES) is an anatomical condition of sella turcica that is partially or completely filled with cerebrospinal fluid mainly due to intrasellar herniation of subarachnoid space. Here, we describe a patient who presented with clinical and biochemical features of acromegaly and who had an ES on pituitary magnetic resonance imaging (MRI). Case report. A 73-year-old male patient was consulted in our clinic because of the acromegalic phenotype while planning for colorectal adenocarcinoma surgery. The patient noticed gradual enlarging of his hands, feet and nose for 30 years, but never consulted to any clinician for this reason. Serum GH was 20.6 ng/mL (normal <3 ng/mL) and IGF-1 was 531 ng/mL (normal, 69–200 ng/ml). An oral glucose tolerance test showed no suppression of GH values. T1-weighted MRI revealed an ES. 18F-FDG PET/CT and Ga-DOTATADE PET/CT did not show any finding consistent with ectopic GH secretion. Growth hormone releasing hormone (GHRH) was within the normal range (<100mg/dL). He was treated with long-acting octreotide 20 mg per 28 days. At the 6th month of treatment, serum GH and IGF-1 levels were decreased to 5.45 ng/mL and 274 ng/mL, respectively. Conclusion. The mechanism underlying the association of acromegaly and ES remains unclear. Apoplexy on existing pituitary adenoma and then formation of necrosis can proceed to ES. Since our patient did not have a history of pituitary apoplexy and we could not find any reason for secondary ES, we considered primary ES.

Severe hypokalemia is a life threatening event, which triggers a number of therapeutic and diagnostic attitudes. In this paper we present a case of 63 years old man, who presented with progressive lassitude, edema, weight loss. The mild hypertension and hyperglycaemia were treated with spironolactone and diet. Initial evaluation showed severe hypokalemia (1.7 mmol/l), hepatomegalia, hyperplasic/nodular adrenal masses; in addition, he has developed a right middle lobe pneumonia which improved with antibiotics. Referred for the suspicion of hyperaldosteronism, aldosterone values were normal (9.3-9.5 ?g/dl), but ACTH was high (725 pg/ml) and did not suppress (710.8 pg/ml) to high dose DXM, as well as cortisol: basal values 27.78 ug/dl, high dose DXM 35.06 ug/dl, showing an ACTH dependent Cushing syndrome despite lack of suggestive clinical signs. Tumor markers suggested a neuroendocrine neoplasia: carcinoembryonic antigen=101 ng/ml (normal values=0.52-6.3 ng/ml), CA 19-9= 155 ng/ml (N < 33 ng/ml). Further radiological evaluation showed a 3 cm right lobe lung tumour. Despite high potassium supplements and spironolactone, the hypokalemia remained around 3.2 mmol/l, characteristic for an apparent mineralocorticoid excess. Because of aggressive evolution of the lung tumour, he died three months after the initial admission into the hospital. Pathology report showed a lung carcinoma. ACTH immunostaining of the lung tumour was positive and revealed a paraneoplastic secretion.

Context. 49,XXXXY syndrome is an aneuploidy that affects males and is commonly referred to as a variant of Klinefelter Syndrome. It presents a frequency of 1:85,000 to 100,000 births and an etiology related to non-disjunction of homologous chromosomes. Findings include skeletal abnormalities, hypogonadism, and cognitive impairment. Turner syndrome is also an aneuploidy of the sex chromosomes, which affects women, and has a prevalence of 1:2000 to 2500 births and a phenotype characterized by short stature and sexual infantilism. Objective. The objective of this article was to study the literature, investigate the family members and report the case. Subjects and Methods. Data collection was based on medical records, family history, karyotype analysis, and FISH analysis. Results. The karyotype of the proband revealed mos 49, XXXXY[45]/46, XY[5]. The patient's mother is affected by mosaic Turner Syndrome low level and the maternal grandmother by inversion of chromosome 9. The father, the younger brother, and the paternal grandmother present variations in the normality of their chromosomes. Conclusions. It is important to highlight that the early diagnosis of the syndrome and the initiation of therapy reduce biopsychosocial impairment. Investigation of other family members makes genetic counseling more effective.

Alteration in nervous system function in patients with thyrotoxicosis is frequent. In rare cases, mental disturbances may be severe: maniac-depressive, schizoid or paranoid reaction. The pathophysiologic basis of these nervous system findings is not well understood. The first patient, being on treatment with benzodiazepine and Risperidone for mood deterioration, was admitted in Thyroid Unit 1 for clinical features suggesting addition, he developed auditory and visual hallucinations, bizarre behavior, disorganized speech, disorientation, poor attention and loss memory for recent events, having a good clinical response after addition of antithyroid drug therapy. The second case developed clinical features suggesting thyrotoxicosis, associated with visual and auditory hallucinations, marked psychomotor agitation and bizarre behavior. After an unsuccessful monotherapy (Risperidone), a good response of clinical features (including psychiatric symptoms) to combined therapy (Methimazole and Risperidone) was recorded. The diagnosis of Graves&#8217; disease was based on clinical and laboratory data (suppressed serum TSH level, elevated serum FT3) and ophthalmological examination or positive anti - TPO antibodies. Both patients were successfully treated with combined therapy - Methimazole and Risperidone. Both case reports demonstrate the importance of performing thyroid function tests in patients with acute psychosis.

Anaplastic thyroid carcinoma (ATC) is the most aggressive type of thyroid\r\ndedifferentiation. Rarely, ATC associates rhabdoid characteristics and only few cases have been\r\npresented to date. We present a case of a thyroid papillary carcinoma which shifted to an\r\naggressive anaplastic form with rhabdoid dedifferentiation and concomitant leukemic reaction\r\nwith eosinophilia. A 76 years old man with a long standing history of a thyroid nodule, noticed\r\nwithin months a rapid growth of the nodule associating marked compression phenomena with\r\nleft deviation of the trachea and esophagus and mild dysphonia. Palliative surgery was\r\nperformed, but the evolution was unfortunate with further health deterioration (fatigue, dyspnea,\r\ndysphagia, loss of appetite and weight loss). Laboratory tests proved leukocytosis with\r\nneutrophilia and left deviation of leukocytes formula, with major eosinophilia. The pathology\r\nshowed a thyroid papillary carcinoma with anaplastic changes. By immunohistochemistry,\r\nit was confirmed the thyroid origin of the tumor (thyreoglobulin positive areas) but also the\r\nepithelial nature of the undifferentiated areas (positive areas for cytokeratin and epithelial\r\nmembrane antigen). Moreover, in the anaplastic areas, rhabdoid differentiation was\r\nidentified by positive coloration against vimentin, protein S100 and desmin. The tumor was\r\naggressive by its anaplastic transformation, confirmed by a high proliferation index (Ki67:\r\n40% positive). The computed tomography was concordant with the phenotype predicted by\r\nhistological description showing a malignant thyroid tumor, invading cervical and mediastinal\r\nareas with secondary lung disseminations. Unfortunately, the outcome was fatal even though\r\nadditional treatment methods have been tried: radiotherapy and chemotherapy. The\r\nparticularities of this case reside in the very rare dedifferentiation of a papillary thyroid\r\ncarcinoma towards an anaplastic thyroid carcinoma harboring the rhabdoid phenotype and\r\nalso its association with eosinophilia.

Prader Willi syndrome (PWS) is a genetic disorder (15q11-q13) characterized by short stature, hypogonadism leading to\r\nosteoporosis, delayed puberty, central hypocorticism and the most life threatening, excessive appetite which is followed by morbid obesity. Patients with PWS present reduced\r\nGH secretion, hypogonadotropic hypogonadism, abnormal appetite control and high pain threshold suggesting\r\nhypothalamic-pituitary dysfunction. However, all high resolution imaging studies are normal; due to changes in Chr\r\n15, the hypothalamic function is disrupted. All patients with PWS show severe disturbances in appetite control resulting in hyperphagia and obesity. Peptides involved in hypothalamic appetite control as ghrelin, leptin, NPY/AGRP, POMC, and their cognate receptors, are involved in developmental processes, determine the threshold for\r\nsignals of body fat below which increases in energy intake and reductions in energy expenditure. In addition, low GH and IGF1 level, central hypothyroidism, delayed puberty and central hypogonadism may impact upon the body composition. Despite the detailed knowledge about obesity mechanisms regulated at hypothalamic level, the pharmacological intervention is limited currently to substitution of proven\r\nendocrine deficiencies and GH treatment. The PWS brain seems "wired" for a positive energy balance, and very few\r\npathways can counterbalance this genetic imprinting.

Abstract Context. Autoimmune progesterone dermatitis (AIPD) is a rare, cyclical dermatosis, with variable clinical presentation, occurring exclusively or being aggravated during the luteal phase of the menstrual cycle, when levels of progesterone rise. Its pathogenesis is still unclear. AIPD is thought to occur as an autoimmune reaction to endogenous possibly modified progesterone, but it could also be triggered by exogenous progesterone exposure. AIPD is a diagnosis of exclusion. Usually there is no or limited response to oral H1 antihistamines and a partial response to steroids. Ovulation inhibitors represent the specific treatment. Case report. We report a case of AIPD in an 18-year-old nulliparous patient with no medical history of allergic diseases and no exposure to oral contraceptive pills. AIPD was suspected based on the clinical picture (recurrent cyclical eczematous eruption on the face and abdominal area) and confirmed by positive intradermal test and positive progesterone challenge. This diagnosis was supported by the result of the skin biopsy, which also helped to exclude other dermatoses with premenstrual aggravation. The rash responded satisfactorily to treatment with a combination of oral contraceptives, levonorgestrel and estrione, which is currently considered first line therapy. Conclusions. This case is of particular interest due to the lack of previous pregnancy or exposure to progesteron therapy. Recurrent, cyclical eruptions in fertile women should raise the suspicion of AIPD. If early recognized, the patient may benefit from non-invasive treatment that improves significantly the quality of life.

Intracranial germ cell tumors (GCTs) include two categories: germinoma and non germinoma. The pineal gland and suprasellar are the most common site of involvement. The patient is a 14-year-old boy who presented with paralysis of upward gaze, polyuria, polydipsia and diplopia. Examination of vertical eye movements was impaired. Puberty then progressed to stage 3 of Marshall - Tanner and had stopped. In laboratory studies, the patient had anterior hypopituitarism and diabetes insipidus (DI). In pituitary and hypothalamic MRIs, a mass-like enlargement of the pituitary stalk and pineal region was seen, but due to the small size of the lesions, stereotactic biopsy was not possible. During this time, the patient developed recurrent attacks of hydrocephalus. Serum and CSF β-subunit of Human chorionic gonadotropin levels were negative. Treatment was not started because different lesions could cause disease in this area. After one year, a biopsy was performed and the germ cell tumor was diagnosed. Chemotherapy was started and after treatment the vision disorder and diplopia disappeared, but DI and pituitary dysfunction remained. Treatment of intracranial germinoma is multidisciplinary. GCTs are very sensitive to radiation therapy. They are treated with combination of chemotherapy, radiotherapy, surgery, endocrine therapy and have a good prognosis.
