Introduction: Oncogenic osteomalasia is a rare paraneoplastic syndrome in which a tumor produces fibroblast growth factor 23 which leads to increased urinary phosphate excretion resulting in hypophosphatemia. It is frequently associated with mesenchymal tumors of bone and soft tissues. We report a case of oncogenic osteomalasia due to lipoma.Case report: A 38-year-old female patient with a 6-year history of left hip pain which progressively worsened over...

Introduction: Neuroendocrine tumors (NETs) are rare tumors harboring overexpression of somatostatin receptors (SSTRs) on their cell membrane. Gallium 68-tetraazacyclododecane tetraacetic acid-octreotate (68Ga-DOTATATE) positron emission tomography/computed tomography (PET/CT) is an important imaging modality in diagnosis and staging of NETs. Because some organs such as spleen, adrenal glands and liver physiologically express SSTR, it might be challenging to distinguish some pa...

Introduction: In pregnancy, the incidence of Primary Hyperparathyroidism is 1%; and there are 80% adenoma, 15% parathyroid hyperplasia, 3% multiple adenoma, and 1% parathyroid carcinoma in its etiology. In pregnancy, serum calcium (Ca) levels may not rise as much as expected. This is associated with hypoalbuminemia, GFR increase, placental Ca transfer, and inhibition of PTH–related bone resorption by estrogen. In pregnancy, hyperparathyroidism is asymptomatic at a rate o...
