Steroid 11-beta-hydroxylase deficiency is a relatively rare form of congenital adrenal hyperplasia (CAH). We describe the case of a 46,XX child, reared as a male, who first presented to us at the age of three years with features of peripheral precocity and hypokalemic hypertension. Based on the clinical and biochemical profile, a diagnosis of 11-beta-hydroxylase deficiency CAH was established, and physiological glucocorticoid replacement was begun. Both hypertension and hypokalemia improved with glucocorticoid supplementation, and at eight years of age, antihypertensives were successfully withdrawn. Regression of left ventricular hypertrophy was also noted at this time. In keeping with the male gender identity, the child underwent hysterectomy, oopherectomy and breast reduction surgery at 13 years of age. We conclude that both hypertension and end-organ damage due to 11-beta-hydroxylase CAH may get reversed following optimal glucocorticoid treatment. Detailed genital examination at birth may help in early diagnosis of this rare disorder, thereby preventing the deleterious consequences of longstanding mineralocorticoid excess.

Introduction Primary hyperparathyroidism (PHPT) is a disease that is usually diagnosed in an asymptomatic state during routine biochemical screening. It generally manifests as a sporadic disease in post-menopausal women. However, in India and developing countries, we continue to see severe skeletal and renal manifestations of the disease. Case report Herein, we describe the case of a 16-year-old adolescent girl who presented with severe manifestations of primary hyperparathyroidism. Biochemically, she had severe parathyroid hormone (PTH)-dependent hypercalcaemia with hypophosphataemia and vitamin D deficiency (serum total Ca – 18.5 mg/dl [8.5–10.5 mg/dl], serum PO4 – 1.9 mg/dl [2.5–4.5 mg/dl], serum ALP – 2015 IU/l [80–240 IU/l], serum 25[OH]D – 19.1 ng/ml [30–100 ng/ml] and serum iPTH > 5000 pg/ml [15–65 pg/ml]). Pre-operatively, she required management with saline diuresis, bisphosphonate, and calcitonin. After surgery, the patient had severe hungry bone syndrome (serum Ca – 4.1 mg/dl, serum PO4 – 2.1 mg/dl, serum ALP > 10,000 IU/l) that required treatment with calcium infusions for almost 3 months. Although the clinical and biochemical picture was suggestive of parathyroid carcinoma, histopathology revealed atypical parathyroid adenoma with low proliferative index. Atypical parathyroid adenoma is a term applied to a neoplasm with ‘worrisome’ features but not fulfilling the ‘absolute histopathological criteria of malignancy’. Conclusions Atypical parathyroid adenoma, a rare cause of PHPT, may be associated with severe manifestations. Although malignancy was not discerned in the immediate post-operative period, we plan to continue long-term follow-up of the patient to look for any signs of recurrence or development of parathyroid carcinoma.

Introduction: Primary hyperparathyroidism (PHPT) is a rare disease in children and adolescents. Early recognition of this disease is important to prevent significant morbidity and mortality. Material and methods: We included 10 consecutive patients with PHPT aged 14 to 19 years of age and followed-up prospectively upto one year after parathyroidectomy. Results: Our cohort included 6 females and 4 males. The mean age of the patients was 16.7 ±1.8 years. The symptoms at presentation were musculoskeletal pain (90%), bone deformity (50%), fracture (30%), proximal myopathy (40%), renal stones (50%), reflux symptoms (40%), and pancreatitis (30%). The mean serum calcium was 3.1 ±0.5 mmol/l, mean serum inorganic phosphorus was 0.9 ±0.3 mmol/l and median serum alkaline phosphatase (ALP) was 1911.5 IU/l (IQR: 522.7-5702.3). The median serum intact parathyroid hormone was 133.5 pmol/l (IQR: 69.5 -178.7) while serum 25(OH)D was 47.7 nmol/l (IQR: 23.7-72.7). Hypercalciuria was observed in 7 patients. Hungry bone syndrome was observed in 4 (40%) patients after surgery. Typical parathyroid adenoma was found in 9 (90%) patients while one patient had atypical adenoma with high mitotic index. After one year of surgery, all patients had significant improvement in clinical and biochemical parameters with persistence of residual bone deformities. Conclusions: Our study showed the spectrum of manifestations of PHPT in children and adolescents and outcomes of parathyroidectomy till one year. Long-term follow-up studies with bigger cohorts are required to understand the true nature of the disease in children and adolescents.

Complete gonadal dysgenesis (CGD) or Swyer syndrome is characterised by sexual infantilism in a phenotypic female with 46, XY karyotype. Patients with gonadal dysgenesis and Y-chromosome material are at a high risk of developing gonadoblastoma and dysgerminoma. A 16-year-old girl presented with progressive virilisation, poor breast development and primary amenorrhea. On evaluation, she was found to have male-range serum testosterone, large abdominopelvic mass lesion, elevated germ cell tumour markers and 46, XY karyotype. She underwent surgical excision of left gonadal mass and right streak gonad, histopathology of which revealed dysgerminoma and gonadoblastoma, respectively. A diagnosis of virilising germ cell tumour arising in the setting of 46, XY CGD was, therefore, made. This case highlights a rare presentation of 46, XY CGD and the need to consider early prophylactic gonadectomy in patients affected with this rare condition. The presence of dysgerminoma/gonadoblastoma should be suspected if a hitherto phenotypic female with CGD undergoes virilisation.
