Polycystic ovary syndrome (PCOS) is a multifactorial, multifaceted syndrome that affects women across all ages from adolescence to post-menopause. It is reported to be the most common endocrinopathy in women of the reproductive age group.1 The nature of this syndrome is such that it requires support and intervention from multiple medical and allied specialties. The treatment […]

Thyroid nodules are common worldwide, and their prevalence is increasing. Most nodules are asymptomatic and detected incidentally on cross-sectional imaging or physical examination. In rare cases (10–15%), nodules are malignant and require diagnostic evaluation. Even malignant nodules frequently show non-aggressive behaviour.1 The increase in the incidence of thyroid cancer is unfairly distributed globally, and the […]

Amyloid goiter (AG) is a benign condition characterized by the deposition of amorphous proteinaceous material in the thyroid gland to an extent that results in detectable enlargement during clinical evaluation.1–3 Amyloid can infiltrate the thyroid gland in 15–50% of individuals with primary amyloidosis (known as “amyloid light chain” or AL amyloidosis) and in 20–80% of patients […]

In the USA, neck ultrasound (US) identifies thyroid nodules (TNs) in 30–50% of adult patients.1,2 Given that the risk of malignancy (ROM) for all combined thyroid nodule types ranges from 5% to 15%,2,3 current guidelines recommend US of the neck initially, to identify suspected TNs.4 Neck US is used to localize TNs, facilitate risk stratification, clarify the necessity […]

Parathyroid carcinoma is a rare endocrine neoplasm with an incidence of 0.5–2.0% of all cases of primary hyperparathyroidism (PHPT).1 It was first described in 1904 by de Quevain, when it was found in a patient presenting with a non-functioning parathyroid mass.2 Around 26 years later, Sainton and Millot described the first functioning parathyroid carcinoma.3 There is no […]

Hypothyroidism usually presents with subtle signs and symptoms. Rarely, longstanding juvenile hypothyroidism can manifest as a syndromic diagnosis of Van Wyk–Grumbach syndrome (VWGS).1 VWGS presents as early menarche, thelarche, galactorrhoea, delayed bone ageing and multi-cystic ovaries, along with long-standing primary hypothyroidism.2 Reversal to the prepubertal state is typically seen following the appropriate treatment with levothyroxine. The present […]

Thyrolipomatosis is a rare condition defined as a diffuse non-neoplastic infiltration of fatty tissue in the thyroid gland.1 Although fatty infiltration is common in other glands (e.g. salivary glands, parathyroids, thymus and pancreas), it is rare in the thyroid gland.2 If present, it is most frequently nodular (i.e. thyrolipoma) rather than diffuse (i.e. thyrolipomatosis).3 Thus, since the first […]

Polycystic ovary syndrome (PCOS) is a heterogeneous syndrome, considered the most common endocrinopathy in women of reproductive age, with a prevalence of 6–8% in premenopausal women.1,2 However, long-term sequelae are extended beyond the reproductive axis, being present from birth to senescence. Consequently, early detection and treatment options are in high demand to prevent long-term complications. This […]

Renal tubular acidosis (RTA) is characterized by the impaired ability of the kidneys to absorb filtered bicarbonate or to excrete titrable acid in urine.1 It manifests as normal anion gap (hyperchloremic) metabolic acidosis. RTA may be of four types: type 1 (distal RTA), type 2 (proximal RTA), type 3 (mixed RTA) and type 4.1 Type 1 […]
