Introduction: Cushing’s disease is usually caused by functional corticotroph microadenomas of the pituitary. Crooke’s cell adenomas are rare, representing approximately 2% of corticotroph adenomas and mostly present as aggressive macroadenomas. Pituitary adenomas showing immunoreactivity for both ACTH and GH are also very uncommon. We present two cases of Cushing’s disease caused by macroadenomas with Crooke’s cell cha...

Introduction: Familial Mediterranean Fever (FMF) is an autosomal recessive hereditary disease characterized by fever and inflammation of serous membranes. The most important complication of FMF is amyloidosis which has significant role in the prognosis. It is unclear how endocrine system hormones are affected in FMF. We present adrenal insufficiency in a an FMF patient without amyloidosis.Case: A 39 years old male patient who had been diagnosed with FMF ...

Introduction: Brown tumor is a rare benign bone lesion with incidence ranging from 1.5% in primary hyperparathyroidism to 13% in secondary hyperparathyroidism. Common sites of involvement are pelvis, femur and ribs, but may appear in any bone. Since the incidence of thyroid disease is higher among patients with hyperparathyroidism than the general population, these lesions must be distinguished from metastases from thyroid carcinoma.We present a patient ...

Diabetes mellitus like all chronic illnesses requires lifelong management (self or guided) with regular health professional support and supervision. Non-attendance at outpatient clinics (OPD) is a common cause of inefficiency in our current health care system causing undue wastage of clinician time and resources and potentially lengthening waiting times.Aim: The aim of our pilot project was to improve our diabetes OPD from the current attendance of 78% t...

BackgroundPPAR-gamma agonists have been proposed as therapy to lower plasma ACTH in Cushing's disease. However, cyclical secretion may explain some of the 'responses' seen. In contrast, patients with Nelson's syndrome have continual high ACTH levels, and can present with pituitary mass effects and pigmentation. Since no established medical therapy exists, we assessed whether prolonged high-dose rosiglitazone therapy reduces circulating ACTH levels in Nel...

Propylthiouracil (PTU) is a widely used drug, and can cause drug-induced vasculitis which is characterized by inflammation and cellular infiltration of small vessels and presence of anti-neutrophil cytoplasmic antibodies (ANCA). We report a case of perinuclear antineutrophil cytoplasmic antibody-associated vasculitis developed during treatment with PTU for Graves’ disease. A 58-year-old woman admitted to the Emergency Department with painful necrotic lesion at her right e...

Oncogenic osteomalacia is a rare paraneoplastic syndrome, which can be associated with phosphaturic mesenchymal tumor or non-mesenchymal tumour. This tumour produces fibroblast growth factor 23 (FGF-23) that leads to subsequent hypophosphataemic osteomalacia. We, hereby present a patient with oncogenic osteomalasia who is misdiagnosed as ankylosing spondylitis. A 54-year old man with weakness, severe arthralgia involving pelvis, hip joints and lower extremities referred to the...

A 41-year-old woman was referred with 9 months history of secondary amenorrhoea and galactorrhoea. She was otherwise well and not taking any medications. Biochemical evaluation showed prolactin 2000 mU/l but otherwise unremarkable. Pituitary MRI revealed a 30 mm pituitary lesion with right cavernous sinus invasion, presumed to be a craniopharyngioma due to the presence of calcification. Surgical intervention was recommended, but the patient declined. She was commenced on caber...
