Introduction: The combination of chemotherapy with prophylatic cranial radiotherapy (C-RT) allowed the improvement of survival rates of pediatric acute lymphoblastic leukemia (ALL) survivors while putting them at risk of develeping long-term endocrine deficiencies, like growth hormone deficiency (GHD).Current evidence suggests that the prevalence of GHD in children treated with radiation doses ≥ 30–50 Gy for non-pituitary brain tumors is...

Background: Papillary thyroid cancer (PTC) is the most common type of thyroid carcinoma, but it rarely presents as an intrathoracic mass with concurrent hyperthyroidism due to Graves disease.Case presentation: A 73-year-old man presented with weight loss. Imaging by computed tomography (CT) documented a large mediastinal mass in the infrathyroidal space separate from the thyroid gland and pulmonary lesions suggestive of metastases. Neck ultrasound showed...

Introduction: Mediastinal paragangliomas are rare. These tumours can be associated with increased morbidity and mortality when invasive growth to the heart, great vessels, esophagus and trachea occurs. Surgical resection, if feasible, is the treatment of choice.Case report: A 50-year-old man presented with severe and refractory left gluteal pain radiating to the posterior thigh for two months. The patient had no relevant medical history and no other symp...

Introduction: the presence of areas with a solid / trabecular growth pattern in differentiated papillary thyroid carcinoma (PTC) represents a source of controversy regarding clinical and prognostic significance and usually requires a more aggressive therapeutic approach. The aim of this study was to compare clinicopathological characteristics, treatments and prognosis of PTC with and without solid component (SC). We also aimed to evaluate whether SC affects patient outcome in ...

Background: Ectopic ACTH secretion from metastatic acinic cell carcinoma (ACC) of the parotid gland is extremely rare. ACC is an uncommon, typically indolent, salivary gland neoplasm. Herein, we report a case of a high-grade ACC later diagnosed with Cushing’s syndrome (CS).Case presentation: A 60-year-old man presented with a laterocervical mass. Computed tomography (CT) documented a 39×38 mm mass on the parotid gland and homolateral cervical l...

Introduction: Neurofibromatosis type 1 is a disease caused by mutations in the tumor suppressor gene NF1.Although pheochromocytoma is a rare manifestation in these patients (~0.1–5.7%), the incidence is significantly higher than that of the general population.Results (case description): A 50 years old female patient had a clinical diagnosis of neurofibromatosis type 1 since she was 5 years old. She received follow-up in ...

Introduction: Activating and inactivating mutations of the GNAS gene (encoding the Gsα protein) cause McCune–Albright Syndrome and Albright’s Hereditary Osteodystrophy, respectively. In both, the bone and the endocrine system are often affected. In McCune–Albright Syndrome the most common endocrine manifestation is precocious puberty, but thyroid lesions and hormonal overproduction are also described. In Albright’s Hereditary Osteodystrophy there m...
