Introduction: Sertoli-leydig cell tumours are neoplasms of ovarian sex cord stromal cells and account for 0.5-2% of ovarian tumours with reported incidence <0.5 % of all ovarian tumours. These tumours usually manifest in women at younger age (in 75 % patients average age of onset <30). Majority of these tumours produce hormones and up to 80% of ovarian Sertoli-Leydig cell tumours can manifest with signs of virilization.Case report: 18 year old fe...

A 46 years old gentleman was referred by his GP to cardiology with 3 weeks history of bilateral leg swelling and rash associated with breathlessness and palpitations. He has no other past medical history to note. He smokes 20 cigarettes a day and works as a manager in a window installation company. He was started on diuretics and further investigations were arranged by cardiology. His symptoms persisted with worsening of skin rash. He was reviewed by GP again 1 month later. He...

Aim: To define a basal Cortisol threshold that could potentially predict the outcome of short synacthen test (SST) and thus reduce the need for performing SST in patients with low clinical probability for adrenal insufficiency.Methods: We analysed SSTs done at our hospital in non-critically ill general medical and endocrine patients, who had abnormal 0900 h Cortisol levels (n=110, male-45, female-65) between January 2016 to March 2016. The SST w...

A 24 year old gentleman presented following an episode where he became ‘sleepy’ and disorientated whilst driving and had to pull over. He was confused and lethargic and paramedics found blood glucose of 2 mmol/l. He gave a 3-week history of extreme lethargy, nausea, epigastric discomfort, blurring of vision and constant hunger. He denied recent weight changes and had no significant past medical/family history. Biochemical evaluation was as follows; Laboratory glucose...

Pituitary apoplexy is a rare but life threatening condition if not diagnosed and treated promptly. Common causes include hypertension, head trauma, major surgery, dynamic pituitary tests, anticoagulant use and pregnancy. In pregnancy, hyperplasia and hypertrophy of the lactotroph cells increase pituitary volume by 45% returning to original size at 6 months post-partum. Pituitary apoplexy is uncommon in pregnancy and an underlying adenoma is usually the cause. Very few...

Grave’s disease is an auto-immune condition associated with hyperthyroidism caused by TSH-receptor antibodies (TRAB) expressed by follicular cells of the thyroid gland. Grave’s ophthalmopathy has been reported in 25% of the patients and is rarely associated with dermopathy and thyroid acropachy. Management is by anti-thyroid drugs, radioactive iodine ablation or surgery, either alone or in combination. We present a rare case of resistant Graves who has detectable ant...

Phaeochromocytoma is a catecholamine producing tumour arising from the adrenomedullary chromaffin cells. It produces hormones such as epinephrine, norepinephrine, catecholamine and dopamine. (1) There have been some case reports describing an association between Brown adipose tissue (BAT) accumulation due to catecholamine excess caused by a phaeochromocytoma. We present a similar case in this abstract. A 77 year old lady was referred to the community geriatricians with symptom...

A 50 year old male presented with left visual field loss, afferent pupillary defect and reduced libido in 1999. Initial pituitary profile showed prolactin 130 000 mu/l (55.4–276), and testosterone was 5 nmol/l (10–27.6). MRI pituitary showed giant pituitary macroadenoma compressing chiasm. He was started on Cabergoline with subsequent improvement in visual fields, prolactin levels and size of adenoma on subsequent MRI. His disease remained stable on ...
