Introduction: Paraneoplastic Cushing’s syndrome is attributed to ectopic ACTH release from a non-pituitary tumor. The lung is frequently the primary site of the underlying neoplasm but sometimes, in cases of advanced metastatic disease, determining the origin may be challenging.Case presentation: A70-year-old man was reffered to our centre for generalised bone pain, lethargy, and important weight loss in the last six months. Before admission, a cont...

Introduction: Clear cell renal carcinoma (ccRCC) is a subtype of renal cell carcinoma, the most frequent one (80%) and usually affecting only one kidney. It is twice as common in men than women between 50 to 70 years old. It can be associated with some genetic conditions that predispose patients to ccRCC, like Von Hipple-Lindau disease. Some clinical observations and molecular studies raised the hypothesis that RCC is a hormone−dependent tumor.Case...

Medullary thyroid carcinoma (MTC) is a rare malignancy arising from parafollicular C cells of the thyroid gland, sometimes due to germline mutations in the RET protooncogene. Testicular cancer is the most common malignancy in men aged 15 - 40 years with survival rates improved by the introduction of cisplatin therapy in the late 1970s. Nonetheless, platinum-based chemotherapy was shown to increase the risk of a solid second cancer with substantially increased site-specific ris...

Introduction: Ectopic ACTH syndromes account for 5–10% of Cushing syndrome, with intrathoracic and gastrointestinal–pancreatic neuroendocrine tumors being the most common causes, followed by small cell lung cancer, adrenal paraganglioma and medullary thyroid carcinoma.Case report: A 50-year-old male hypertensive and diabetic patient was transferred to our clinic for emergency endocrine care for hypokalemia. He had mild hypercortisolism and live...

Introduction: We describe the case of a 68-year-old patient, having two MEN1-associated tumors that are not part of the classical triad, with a penetrance of only 40%, and 2%, according to the medical literature. Furthermore, she developed a persistent hyperkalemia after the unilateral adrenalectomy, which is rare and often missed.Case report: In 2011, following a non-specific symptomatology (dry cough, fatigue), a bilobectomy was performed (medium and r...

Erdheim-Chester disease (ECD) is a rare histiocytic neoplasm with distinctive clinical and immunophenotypic features, involving somatic mutations of BRAF and activation of MAPK pathway. Other BRAF mutated neoplasms such as papillary thyroid carcinoma (PTC), may also occur synchronous with EDC. There are several reports in the literature of concurrent Langerhans Cell Histiocytosis (LCH) and PTC which suggests that the association is not random, howeve...
