Introduction: Hyperpigmentation is a clinical sign that can be associated with different endocrine disorders. It is commonly seen in Addison’s disease and has rarely been reported in Graves’ disease. The exact physio pathological mechanism of this sign is not well established in hyperthyroidism. We describe two cases of Graves’ disease accompanied by diffuse hyperpigmentation.Case report: Case 1 was a 63-year-old female ad...

Introduction: Moyamoya disease is a rare angiopathy characterized by a progressive stenosis of the intracranial internal carotid arteries (ICA). First described in 1957, its pathophysiological mechanisms are still not well understood. Its association with various systemic diseases is termed moyamoya syndromeObservation: A 21-year-old female patient, with a family history of hypothyroidism, was admitted initially with stroke. The clinical examination reve...

Introduction: 11-Beta-hydroxylase deficiency (11β-OHD) is the second most common cause of congenital adrenal hyperplasia. It leads to the accumulation of steroids precursors prior to the enzyme defect, notably 11-deoxycorticosterone (DOC), leading therefore to low renin hypertension and hypokalemia. Hence, patients with 11β-OHD are reportedly protected from adrenal crisis. Here, we report a case of a male with 11β-OHD presenting with acute adrenal insufficiency....

Introduction: Pituitary neuroendocrine tumors (PitNET) represent 15.5% of primary brain tumors and they can be clinically functioning or non-functioning. Although they are mostly benign, PitNET may be invasive in 30-45% of cases and aggressive in at least 15%. Here, we report the case of a patient who presented a multiple and rapid recurrence of a non-functional pituitary macroadenoma.Observation: A 42-year-old man was admitted initially for headaches, m...

Introduction: Klinefelter syndrome is the most prevalent male chromosomal disorder, characterized by the presence of additional X chromosomes. Most males with Klinefelter syndrome have 47, XXY and normal intelligence. Intellectual disability occurs in males with Klinefelter syndrome variants, who have a higher number of X chromosomes. Here we report a rare case of a 49, XXXXY syndrome revealed by intellectual deficit and pubertal delay.Observation: An 18...

Introduction: Thyroid-associated orbitopathy is an autoimmune disease of the retroocular tissues commonly associated with Graves’ disease (GD) and rarely reported in Hashimoto’s thyroiditis (HT). GD and HT are autoimmune thyroid disease which are sometimes hard to distinguish from one another and their association in one person is rarely described. Here, we report a case of an exacerbation of thyroid-associated orbitopathy in a patient with GD following a SARS-CoV-2 ...

Introduction: Pituitary insufficiency is a late-onset sequel of cranial irradiation for nasopharyngeal tumors. In a Cancer Survivor Study, 43% of patients treated for nasopharyngeal tumors had one or more endocrinopathies. We aim to characterize the pituitary-related outcomes following cranial radiotherapy for nasopharyngeal tumors over a period of 5 years.Material and methods: The effects of cranial irradiation on hypothalamic-pituitary function were st...

Introduction: Cushing’s disease (CD) is associated with metabolic and cardiovascular comorbidities that can be incompletely resolved after disease remission. Our objective was to evaluate the metabolic and cardiovascular status of patients with MC in remissionPatients and methods: We performed a retrospective study including 15 CD patients cured by pituitary surgery. Patient’s medical records were reviewed and information regarding blood pressu...

Background: Antithyroid drugs (ATD) are indicated as first intension in the treatment of Graves’disease (GD). Only two molecules are marketed in Tunisia: Benzylthiouracil (BTU) and Methimazole (MMI). There is still no clear conclusion about the choice of appropriate drug. Our objective was to compare the MMI treatment with the BTU in terms of efficacy and adverse effects (AEs).Methods: It’s a retrospective study. We studied patients with a firs...

Introduction: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders that result from the deficiency of one of several enzymes involved in the steroidogenic pathway for cortisol biosynthesis. The most common cause of CAH, accounting for 90% of cases, is 21-hydroxylase deficiency. The symptoms of disease very depending on the nature and severity of the enzyme deficiency as well as the sex of the individual. Non-classical CAH is generally late onset. Ho...
