Introduction: Pancreatic neuroendocrine tumors (PNET) are rare, with an incidence of 1/100,000/year. Chromogranin A (CgA) is the most valuable marker in the diagnosis and monitoring of PNET. One of the disadvantages is its low specificity and the existence of a number of processes leading to an increase in its concentration, which often results in confusion and diagnostic difficulties.Case report: We present a 44-years-old female patient...

Background: Prolactinoma is the most frequent pituitary tumour. However, peculiar aspects may induce difficulties in their evolution and management. Malignant prolactinoma is exceptionally rare and it cannot be diagnosed on histological grounds alone. We report the case of a recurrent, possibly malignant macroprolactinoma.Case report: 46 years old female, addressed for bitemporal hemianopia, without other clinical signs. MRI confirmed a pituitary macroad...

Introduction: Hypothalamic–pituitary–adrenal (HPA) axis activation is the main neuroendocrine response to an environmental challenge. Drug abuse may activate HPA axis by interaction with neuromodulation systems.Case report: 28 year old man, was admitted in the Neurology Department for persistent headache with spinal irradiation. With suspicion of multiple sclerosis, MRI revealed pituitary macroadenoma (14 mm diameter) and subcortical, paraventr...

Introduction: Nonoccupational postexposure prophylaxis (nPEP) is a three-drug antiretroviral regimen used to decrease the risk for HIV infection after less than 72 h from nonoccupational exposure to body fluids that might contain HIV. The most frequent side effects concern the gastro-intestinal intolerance, renal and hepatic toxicity, with no hormonal imbalance to have been yet reported.Case report: 24 years old male patient, consulted for palpitations, ...

Introduction: Many causes of malabsorbtion of levothyroxine (LT4) in patients with hypothyroidism have been thoroughly described in literature. Pseudomalabsorption, poor compliance of the patient is most common cause of failure of LT4 and/or liothyronine (LT3) treatment.Case report: 27 years old woman, normopondeal, presented from the age of 11 years for short stature. Further investigations found pluritrope pituitary insufficiency ...

Introduction: The coexistence of pituitary adenoma and meningiomas is very rare. It is debatable if meningiomas result as a consequence of hormone dependent growth or secondary to radiation.We report a rare case of coexisting brain tumors: a prolactin secreting pituitary adenoma and two meningiomas in a 54-year-old female patient.Case report: Onset at 46 years with bitemporal hemianopsia, without other clinical complaints. MRI conf...

Introduction: Legg calvé perthes (LCP) is a disease characterized by idiopathic avascular necrosis of the proximal femoral epiphysis caused by decreased blood flow. More frequently in boys between 2 and 12 years of age. LCPD is of unknown etiology.We present two male patients of LCP associated with pituitary disorders.Case presentation: Case 1: g.i.c., 8 years 8 month, was first addressed to the endocrinology department for in...

Background: Normal thyroid function is necessary for the optimal effect of recombinant growth hormone (rhGH) on growth rate. GH therapy in children with GH deficiency (GHD) has yielded conflicting results concerning its impact on thyroid function. Data about patients developing subclinical hypothyroidism (SH) are scanty, but it is thought to be associated with impairment of metabolic profile and lower growth response.Objective: To evaluate the effect of ...

Introduction: Hypophysitis is a chronic inflammatory condition of the pituitary gland which typically presents with hypopituitarism and a pituitary mass. The disease is rare, with an estimated incidence of 1/9000000. Most reported cases are in women during peripartum period and only approximately 15% of reported cases occur in males.Case report: Male patient, aged 57, smoker, with a history of hypertension, just returned from India, presented with anorex...
