PURPOSE: Pheochromocytomas (PCCs) exhibit malignant potential, but current histological modalities for the proper detection of aggressive behavior are debated. The two most widespread algorithms are the "Pheochromocytoma of the Adrenal Gland Scaled Score" (PASS) and the "Grading System for Adrenal Pheochromocytoma and Paraganglioma" (GAPP), both which mostly rely on histological parameters to identify PCC patients at risk of disseminated disease. Since the algorithms are derived from studies using predominantly sporadic PCCs, little is known whether the PASS or GAPP scores can predict malignant potential in hereditary cases...

Pheochromocytoma (PCC) is a tumor derived from adrenomedullary chromaffin cells. Prognosis of malignant PCC is generally poor due to local recurrence or metastasis. We aim to report a case of malignant PCC with 18-year survival and discuss which factors may be related to mortality and long-term survival in malignant pheochromocytoma. The patient, a 45-year-old man, reported sustained arterial hypertension with paroxysmal episodes of tachycardia, associated with head and neck burning sensation, and hand and foot tremors...

Pheochromocytomas (PHEOs) are rare neuroendocrine tumors and about 2-13% of PHEOs are malignant. Predicting malignancy in PHEO cases with invasion but without metastasis is still controversial in the literature. This study presents an unusual long survival with a giant invasive PHEO in an incompatible patient and a review of the literature. In 1989, a 23-year-old female patient was operated for a giant adrenal mass with a pathological final diagnosis of PHEO. Information to the patient's family was provided about the short life span of the patient in the postoperative period because the tumor could not be totally resected...

Pheochromocytoma is very rare at a pediatric age, and when it is present, the probability of a causative genetic mutation is high. Due to high costs of genetic surveys and an increasing number of genes associated with pheochromocytoma, a sequential genetic analysis driven by clinical and biochemical phenotypes is advised. The published literature regarding the genetic landscape of pediatric pheochromocytoma is scarce, which may hinder the establishment of genotype-phenotype correlations and the selection of appropriate genetic testing at this population...

The investigation and management of unilateral adrenal incidentalomas have been extensively considered in the last decades. While bilateral adrenal incidentalomas represent about 15 percent of adrenal incidentalomas, they have been less frequently discussed. The differential diagnosis of bilateral incidentalomas includes metastasis, primary bilateral macronodular adrenal hyperplasia (BMAH) and bilateral cortical adenomas. Les frequent etiologies are bilateral pheochromocytomas, congenital adrenal hyperplasia, Cushing's disease or ectopic ACTH secretion with secondary bilateral adrenal hyperplasia, primary malignancies, myelolipomas, infections or hemorrhage...

Objectives We retrospectively investigated the clinical and endocrinological characteristics of adrenal incidentalomas. Methods We studied 61 patients who had been diagnosed with adrenal incidentalomas and had undergone detailed clinical and endocrinological evaluations while hospitalized. We used common criteria to diagnose the functional tumors, but for sub-clinical Cushing's syndrome, we used an updated set of diagnosis criteria: serum cortisol ≥1.8 μg/dL after a positive response to a 1-mg dexamethasone suppression test if the patient has a low morning ACTH level (<10 pg/mL) and a loss of the diurnal serum cortisol rhythm...

Pheochromocytoma is a rare tumor of the adrenal gland. It often presents with the classic triad of headache, palpitations and generalized sweating. Although not described as a typical symptom of pheochromocytoma, anxiety is the fourth most common symptom reported by patients suffering of pheochromocytoma. We report the case of a 64 year old man who had severe anxiety and panic disorder as presenting symptoms of pheochromocytoma. After 13 years of psychiatric follow-up, the patient was diagnosed with malignant pheochromocytoma...

Bovine adrenal gland tumours are considered relatively common, although scarce data are available about their real incidence, pathological characterization, classification criteria and immunohistochemical profile. This study describes the morphological and immunophenotypical characteristics of 35 dairy cattle adrenal gland tumors from Northern Italy and compare them with human pathology. Macroscopical, histological, histochemical and immunohistochemical investigations were performed. Microscopically proliferative lesions were classified as focal hyperplasia (8/35), primary cortical tumors (15/35) , primary medullary tumors (12/35)...

Pheochromocytomas are uncommon neuroendocrine tumors of the adrenal medulla. Malignant behavior is seen in approximately 10% of these lesions, evidenced by distant metastasis to sites without chromaffin tissue. The authors report a rare case of intracranial epidural metastases of an adrenal pheochromocytoma in a 24-year-old man. The patient originally presented at the age of 10 years with adrenal pheochromocytoma and subsequently developed extensive metastatic bone and lung disease. He was monitored in the intervening years until recent imaging demonstrated an enlarging right parietal mass...

This study aimed to explore the efficacy of propofol to treat malignant pheochromocytoma (PCC) in vitro and in vivo. In vitro, PC12 cells were treated with different concentrations of propofol (0, 1, 5, and 10 μg/mL) for specific times followed by a MTT assay to detect cell proliferation. Transwell assays were performed to assess the function of propofol on the migration and invasion of PC12 cells, and flow cytometry to analyze cell apoptosis and cell cycle progression. Quantitative real-time polymerase chain reaction was carried out to analyze the expression level of mRNA (Bcl-2, Bax, and CyclinE)...

PURPOSE: Treatment of malignancies invading the hepatic veins/inferior vena cava is a surgical challenge. An ante situm technique allows luxation of the liver in front of the situs to perform tumor resection. Usually, cold perfusion and veno-venous bypass are applied. Our experience with modified ante situm resection relying only on total vascular occlusion is reported. METHODS: Retrospective analysis on an almost 15-year experience with ante situm resection without application of cold perfusion or veno-venous bypass RESULTS: The ante situm technique was applied on eight patients...

The giant cystic pheochromocytoma is a rare adrenal tumor in the predominantly asymptomatic course; so many cases are not diagnosed until the time of surgery. The simple mobilization of the tumor is associated with the passage to the blood of large amounts of catecholamines and high morbidity and mortality. So the surgery itself and perioperative management are a huge challenge. This article describes the case of a malignant giant pheochromocytoma (35 cm) which occupied the entire right abdomen. Even with the preoperative diagnosis of pheochromocytoma, pharmacological blockade preoperative and intraoperative measures, the patient died shortly before the end of surgery...

INTRODUCTION: In the MEN 2A syndrome, which is the most common of the three types of MEN, three endocrine systems are affected simultaneously or subsequently by the development of tumours manifested by medullary thyroid gland carcinoma, pheochromocytoma (often bilateral) and hyperparathyroidism. MATERIAL AND METHODS: 27 patients from 3 families affected by MEN 2A syndrome were examined clinically (by detecting the effects of catecholamine overproduction), biochemically (screening for metanephrine and normetanephrine in the serum), visualization (CT, MRI, MIBG, PET CT) and some of them also genetically (DNA fragment analysis obtained by PCR amplification)...
