Paraganglioma of the bladder is a rare tumour accounting for less than 0.06% of all urinary bladder tumours and has varied presentations. It may present with clinical symptoms of phaeochromocytoma, may be non-functioning and asymptomatic or may present with haematuria. Hence, paragangliomas are occasionally misdiagnosed, and this results in unanticipated intraoperative hypertensive crisis. We present the case of a 44-year-old woman with urinary bladder paraganglioma who presented with young onset hypertension, recurrent micturition syncope with prior history of coronary artery disease and stroke. She was stabilised preoperatively with alpha blocking agents and subsequently underwent successful transurethral resection of the same., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

McCune Albright syndromeis a rare disorder that presents with multiple endocrine abnormalities. We report the case of a 24-year-old woman who presented with right lower limb pain, with no preceding trauma or fracture. On examination she was noted to have coarsened facial features, acral enlargement, bitemporal hemianopia, galactorrhoea and multiple café-au-lait macules. She gave history of precocious puberty, having attained menarche at 7 years of age. Biochemical investigations revealed hyperprolactinaemia, with unsuppressed growth hormone levels following a glucose load and subclinical hyperthyroidism. Technetium-99m methylene diphosphonate bone scan showed polyostotic fibrous dysplasia, MRI of the brain showed a pituitary macroadenoma. Thus she was diagnosed to have McCune Albright syndrome with multiple endocrine manifestations. She was treated with parenteral zoledronate for her bony lesions and initiated on cabergoline for plurihormonal pituitary macroadenoma. She is planned to be on close follow-up to assess for clinical improvement and appearance of other manifestations., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019.

Oncogenic osteomalacia is a potentially curable condition caused by phosphaturic mesenchymal tumours. We present the case of 54-year-old woman who presented with bony pains and muscle weakness, and was erroneously treated with bisphosphonates elsewhere on the basis of Dual Energy X-ray Absorptiometry (bone density) scan that showed 'severe osteoporosis'. Further evaluation revealed the presence of hypophosphatemia, with a 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid avid lesion involving left mandible on PET scan. Surgical excision of lesion led to improvement in her symptoms with normalisation of phosphorus, and histopathology was diagnostic of mesenchymal phosphaturic tumour. A diagnosis of oncogenic osteomalacia was made. A repeat bone mineral density assessment done a year later showed dramatic improvement. A meticulous examination and evaluation is warranted for any patient presenting with bony pains and muscle weakness. The detection of hypophosphatemia in an elderly individual should prompt the consideration of oncogenic osteomalacia, as localisation and excision of tumour usually results in cure., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019.

Klinefelter syndrome is usually characterised by the presence of a eunuchoid body habitus and testes that are usually small and firm, with low testosterone, and elevated luteinising hormone and follicle-stimulating hormone levels, consistent with hypergonadotropic hypogonadism. Low levels of gonadotropins in karyotypically proven cases are not expected, they are extremely rare occurrences. We report a case of a patient who was diagnosed to have Klinefelter syndrome (47 XXY) with low gonadotropin levels. The rest of his anterior pituitary hormonal profile was normal with no lesions in the pituitary gland on imaging. He was continued on androgen replacement therapy., (2015 BMJ Publishing Group Ltd.)
