PURPOSE: Therapeutic options for patients with malignant pheochromocytoma are currently limited, and therefore new treatment approaches are being sought. Targeted radionuclide therapy provides tumor-specific systemic treatments. The β-emitting radiopharmaceutical meta-131I-iodo-benzylguanidine (131I-MIBG) provides limited survival benefits and has adverse effects. A new generation of radionuclides for therapy using α-particles including meta-211At-astato-benzylguanidine (211At-MABG) are expected to have strong therapeutic effects with minimal side effects...

PURPOSE: Bone metastases (BM) and skeletal-related events (SRE) are frequent in patients with malignant pheochromocytoma and paraganglioma (PPM) and the best modality of prevention unknown. The role of interventional radiology (IR) techniques for the prevention of SRE in the multidisciplinary management of malignant PPM has not been evaluated in that setting. METHODS: Single referral center retrospective review of all patients with malignant PPM with BM from 2000 to 2016...

Mini-invasive surgery is more and more integrated in pediatric surgery. The robotic-assisted surgery brought new advantages from which the patient and the surgeon could benefit compared to laparoscopy. Its use in oncological surgery is still controversial. 12 robotic-assisted tumor resections with the da Vinci Surgical Robot (Intuitive Surgical, Sunnyvale, CA) were attempted in 11 children (mean age 7.65 years; age range 0.75-16.75 years; mean weight 30.3 kg; weight range 8.6-62 kg) in two centers. Mean total operative time was 145 min (range 72-263 min)...

BACKGROUND: Recent advance of genetic testing has contributed to the diagnosis of hereditary pheochromocytoma and paraganglioma (PPGL). The clinical characteristics of hereditary PPGL are varying among the types of mutational genes. It is still difficult to specify the pathognomonic symptoms in the case of rare genetic mutations. Here, we report the case of synchronous bilateral pheochromocytomas and paraganglioma with novel MYC associated factor X (MAX) gene mutation. CASE PRESENTATION: A 24-year-old female had hyperhidrosis and hypertension...

There are two problems that needs to be addressed in cases of an adrenal incidentaloma. The first is to decide whether the adrenal mass is benign or malignant, and the second is to determine whether the mass is hormonally active or not. A 17-year-old male was admitted with the complaint of progressive weight gain. Abdominal ultrasonography was performed for elevation in transaminases which revealed a hypoechoic mass located in the left adrenal gland...

Pheochromocytoma is a rare tumor originating from the embryonic neural crest and secreting high levels of catecholamines. The average tumor size is approximately 7 cm, and the average weight is approximately 200 g in the previous publications. Sometimes these tumors may be bigger. In this report, a case of multicystic malignant pheochromocytoma with a huge size is presented, which is seldom reported in the past. A 37-year-old male patient was referred to our hospital for etiological investigation of his recently diagnosed hypertension...

BACKGROUND: Pheochromocytomas are rare neuroendocrine tumors, with a malignancy frequency of approximately 10%. The treatment of malignant pheochromocytoma is palliative, and the traditional management strategy has limited efficacy. Furthermore, no clear criteria exist for the treatment of metastatic pheochromocytoma, especially for unresectable lesions. We report a case of complete remission of metastatic pheochromocytoma in 123I-metaiodobenzylguanidine (MIBG) scintigraphy after a single session of 131I-MIBG therapy...

Malignant pheochromocytoma (PHEO) and paraganglioma (PGL) (PHEO and PGL: PPGL) are frequently associated with bone metastasis. Bone metastasis requires long-term management and may lead to skeletal-related events (SREs) that remarkably reduce patients' quality of life (QOL). The aim of this study was to elucidate the risk factors for developing bone metastasis in patients with PPGL. The medical records of 40 consecutive adult patients with malignant PPGL at the National Hospital Organization Kyoto Medical Center between 2006 and 2016 were reviewed...

The 2017 Endocrine Society annual meeting included several communications and debates on the conservative adrenal surgery in bilateral hereditary pheochromocytomas (BHP), bilateral adrenal macronodular hyperplasia (BAMH) and primary hyperaldosteronism (PHA). The general principle is to preserve a part of the adrenal cortex to prevent the occurrence of a definitive adrenal insufficiency. In BHP, cortical sparing surgery allows more than 50% of patients to maintain normal corticotropic function at 10 years with a low recurrence rate (~ 10%)...

Six syndromes of familial hyperparathyroidism are compared: 1) Familial hypocalciuric hypercalcemia (FHH) expresses primary hyperparathyroidism (PHPT) beginning at birth with lifelong hypercalcemia. There is nonsuppressed PTH secretion from outwardly normal parathyroid glands. It reflects germline heterozygous mutation in CASR, GNA11, or AP2S1. 2) Neonatal severe primary hyperparathyroidism is severest of the six syndromes. It requires urgent total parathyroidectomy in infancy. It usually reflects biallelic inactivation of the CASR...

Neuroendocrine tumors (NET) represent the variability of almost benign lesions either secreting hormones occurring as a single lesion up to malignant lesions with metastatic potential. Treatment of NET is usually performed by surgical resection. Due to the rarity of NET, surgical treatment is mainly based on the experience and recommendations of experts and less on the basis of prospective randomized studies. In addition, the development and establishment of new surgical procedures is made more difficult by their rarity...

Pheochromocytomas (PCCs) and paragangliomas (PGLs) are neuroendocrine tumors with a strong genetic background. The mainstay of treatment for PCC/PGLs is surgery. However, for unresectable lesions, no curative treatment is currently available. Temozolomide (TMZ) has been shown to determine radiological and biochemical response in malignant PCC/PGLs. We report two cases of PCC/PGLs treated with TMZ. Case 1 is a 51-year-old man with local and distant recurrence (liver and bone metastases) of right adrenal PCC...

Most patients with hypertension have no clear etiology and are classified as having primary hypertension. However, 5% to 10% of these patients may have secondary hypertension, which indicates an underlying and potentially reversible cause. The prevalence and potential etiologies of secondary hypertension vary by age. The most common causes in children are renal parenchymal disease and coarctation of the aorta. In adults 65 years and older, atherosclerotic renal artery stenosis, renal failure, and hypothyroidism are common causes...

We report on a 43-year-old, asymptomatic female who presented with incidental finding of left adrenal mass. MRI gave concerns for possible pheochromocytoma but markers for pheochromocytoma were not elevated as expected. 24-hour urine dopamine levels (6988 μg/day) were significantly elevated. The patient successfully underwent robotic assisted radical left adrenalectomy and was diagnosed with a dopamine secreting pheochromocytoma. Pathology revealed increased malignant potential associated with the tumor...

We report a rare case of a 25-year-old lady who presented with right hypochondriac pain associated with weakness for 3 months. Her hormonal evaluation was normal. Computed tomography scan revealed an adrenal mass for which a right open transperitoneal adrenalectomy was performed, and the lesion was diagnosed as mature teratoma on histopathological examination. Teratoma is an unusual neoplasm which arises from one or all the three germ layers. Extragonadal teratomas are rare in adults as compared to children and are mostly retroperitoneal in location, constituting only 4% of all primary teratomas...
