Background: Hypoparathyroidism is an endocrine disorder characterized by hypocalcemia due to low levels of parathyroid hormone (PTH). Activated vitamin D (calcitriol) and calcium supplementation may be difficult in patients with malabsorption, as calcium requires an acid environment to dissolve. In this setting, subcutaneous administration of PTH analogues may be effective in reducing the dosage of oral calcium and vitamin D supplementation.Case report: ...

Background: Diffuse large B-cell lymphoma is the most common non-Hodgkin’s lymphoma (NHL). It can involve extranodal sites in about 30%, but the involvement of endocrine organs is rare (adrenal involvement is estimated<0.2%) and correlates with poor prognosis. In contrast to pituitary metastases from solid tumors, NHL involvement of the anterior lobe of the pituitary is more frequently seen.Case presentation: A 84-year-old woman presented to the...

Background: Cushing’s syndrome (CS) is characterized by inappropriate cortisol secretion and its diagnosis is still challenging for endocrinologist. Nevertheless, CS is a rare condition, making difficult to collect data and establish tests’ diagnostic performances.Objectives: Assessing diagnostic performances of Urinary Free Cortisol (UFC) evaluated by liquid chromatography method coupled with tandem mass (LC-MS/MS) and Late Night Salivary Cort...

Background: Cushing’s syndrome (CS) in medullary thyroid cancer (MTC) is rare with less than 60 cases reported. Less than 1% of MTC develop ectopic ACTH-dependent CS and this correlated with metastasis at diagnosis and poor prognosis.Case presentation: A 32-year-old male was referred to our department for suspected CS. Initial evaluation showed hypokalemia(2.4 mmol/l) and severe ACTH-dependent CS (Cortisol h8:678ng/ml; ACTH:249pg/ml; urinary free co...

Background: Lenvatinib is an oral chemotherapy for metastatic radioiodine-refractory differentiated thyroid cancer (RRDTC) which significantly improves progression free survival (PFS). It has been proved that higher rates of dose interruption or reduction of Lenvatinib have a negative impact on PFS. Patients with active cancer, such as RRDTC, have an increased risk of contracting Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) and developing complications, especial...
