RATIONAL: Primary malignant melanoma of the gallbladder is an extremely rare tumor, with fewer than 40 cases reported in the literature worldwide. The majority of patients presented as a solitary lesion in the gallbladder. To our knowledge, only one case of primary malignant melanoma of the gallbladder with multiple metastases has been reported, which involved the stomach, duodenum, pancreas, jejunum and a mesenteric lymph node. PATIENT CONCERNS: We report a case of primary malignant melanoma of the gallbladder with metastases to the duodenal bulb, right adrenal and a celiac lymph node...

OBJECTIVE: Pheochromocytomas and paragangliomas (PPGLs) are neuroendocrine tumors derived from adrenal or extra-adrenal locations, respectively. Upon suspicion of PPGL, specific metabolomic, molecular, biochemical, imaging, and histopathological studies are performed to prove, localize, treat, and monitor disease progression. Recently, improved diagnostic tools allow physicians to accurately diagnose PPGL, even in patients presenting with small (less than 1 cm) or biochemically silent tumors, which previously delayed proper detection and treatment...

Rats affected by the MENX syndrome spontaneously develop multiple neuroendocrine tumors (NETs) including adrenal, pituitary and thyroid gland neoplasms. MENX was initially reported to be inherited as a recessive trait and affected rats were found to be homozygous for the predisposing Cdkn1b mutation encoding p27. We here report that heterozygous MENX mutant rats (p27+/mut) develop the same spectrum of NETs seen in the homozygous (p27mut/mut) animals but with slower progression. Consequently, p27+/mut rats have a significantly shorter lifespan compared with their wild-type (p27+/+) littermates...

Classic antidepressant drugs are modestly effective across the population and most are associated with intolerable side effects. Recently, numerous lines of evidence suggest that resveratrol (RES), a natural polyphenol, possesses beneficial therapeutic activity for depression. The aim of the present study was to explore whether RES exhibits an antidepressant-like effect in a depression model and to explore the possible mechanism. A depression model was established via chronic unpredictable mild stress (CUMS), after which the model rats in the RES and fluoxetine groups received a daily injection of RES or fluoxetine, respectively...

RATIONALE: Angiosarcoma is an extremely rare malignant tumor of endothelial origin. The majority of studies reporting angiosarcoma have been concerned with the clinical and pathological aspects, with limited reporting of their imaging findings. To our knowledge, angiosarcoma of the adrenal gland is very rare. Herein we firstly report a primary adrenal angiosarcoma depicted on magnetic resonance imaging (MRI). PATIENT CONCERNS: A 59-year-old man was referred to our hospital for 1 year left-flank pain that exacerbated in recent 4 months...

With the development of laparoscopic adrenalectomy, indications for resection gradually span from small and benign to bigger and even malignant lesions. We studied the results of laparoscopic adrenalectomy for giant (>10 cm) adrenal tumors in three cases. Three patients (2 female, 1 male, mean age 49.33 years, BMI 31) underwent laparoscopic transperitoneal adrenalectomy due to giant (>10 cm) adrenal lesions with a limited size Pfannenstiel incision. Mean operative time was 126.66 minutes, with a mean intraoperative blood loss of 150 ml...

Hepatocellular carcinoma (HCC) is the sixth most common cause of death worldwide and the main cause of primary liver cancer. The principle problem of HCC is the poor prognosis, since advanced HCC reportedly has a median survival of only 9 months. The standard therapies are sorafenib and regorafenib, but the outcomes remain unclear. We report a 60-year-old man with advanced HCC with right adrenal gland metastasis and portal vein tumor thrombosis, who showed a complete response to multiple applications of an interdisciplinary therapy...

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...

Pulmonary squamous cell carcinoma is the second most common non-small cell malignancy of the lung. It commonly metastasizes to the adrenal glands, bone, liver, brain, and kidneys. Most occurrences of metastatic squamous cell carcinoma involving the gastrointestinal tract originate from primary lung tumors. Metastasis to the duodenum, however, is exceedingly rare, with very few cases of stomach or duodenal involvement described in the literature. We report the case of a patient with stage IV pulmonary squamous cell carcinoma metastasizing to the duodenum with an uncommon presentation to add to the paucity of literature available regarding this rare finding...

CONTEXT: Pheochromocytoma and paraganglioma are rare neuroendocrine tumors which overproduce catecholamines and arise from the adrenal gland or extra-adrenal chromaffin cells of the sympathetic and parasympathetic ganglia (1). Excessive catecholamine-induced stimulation of cardiac myocytes leads to damage which manifests in several forms ranging from Takotsubo to dilated cardiomyopathy. Diagnosis of pheochromocytoma-related cardiomyopathies is often delayed due to the atypical presentation associated with many cases...

Pheochromocytoma (PHEO) and paraganglioma (PGL) are rare catecholamine-producing neuroendocrine tumors arising from adrenal medulla or extra-adrenal sympathetic and parasympathetic ganglia. Most of the PHEOs/PGLs are benign tumors, but metastatic disease is common, especially in patients with particular genetic background. Although PHEOs/PGLs were described more than a century ago, diagnosis and therapy of metastatic disease are still challenging. Advances in understanding molecular and metabolic changes associated with tumorigenesis lead us to identification of the background of these tumors...

PURPOSE: The Grading system for Adrenal Pheochromocytoma and Paraganglioma (GAPP) was proposed for predicting the metastatic potential of pheochromocytoma and paraganglioma to overcome the limitations of the Pheochromocytoma of the Adrenal Scaled Score (PASS). However, to date, no study validating the GAPP has been conducted, and previous studies did not include mutations in the succinate dehydrogenase type B (SDHB) gene in the score calculation. In this retrospective cohort study, we validated the prediction ability of GAPP and assessed whether it would be improved by inclusion of the loss of SDHB immunohistochemical staining...

Melanotic Schwannoma (MS) is rarely seen and potentially malignant neoplasm that is categorized as a variant of Schwannoma. MS most frequently involves intracranial structures followed by posterior nerve roots in the spinal canal. Approximately 50% of the cases with MS have psammomatous calcifications and this type of MS is related to Carney complex with autosomal dominant inheritance. Most cases of MS are benign, though 10% of them are malignant with metastatic potential. MS mimics melanoma and the differential diagnosis should be made excluding other melanin producing neoplasms especially melanoma...

INTRODUCTION: Pancreatic neuroendocrine tumors are rare. Treatment includes aggressive local management of the primary lesion and metastases, and systemic somatostatin. This is the first report of an isolated metachronous metastasis to the adrenal gland from a pancreatic neuroendocrine tumor that presented 90 months after the primary tumor. PRESENTATION OF CASE: The patient presented as a 53yo man with a left upper quadrant mass and synchronous metastases to the spleen and liver (pancreatic neuroendocrine tumor T4N0M1, Stage IV), which were resected (CD56-, synaptophysin+, chromogranin+, Ki-67<1%)...

Exposure to psychosocial stress can have a profound impact on immune reactivity and health mediated by hypothalamic-pituitary-adrenal (HPA) axis activation. However, current knowledge regarding the mechanisms involved in cross-sensitization between stress and the immune system is limited. Here, we investigated the effects of a single social isolation followed by repeated oral Escherichia coli (E. coli) applications on cortisol, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), haptoglobin and C-reactive protein (CRP) concentrations in the blood; on clinical signs of disease; and on mRNA expression of the glucocorticoid receptor (GR), mineralocorticoid receptor (MR), 11β-hydroxysteroid dehydrogenase 1 and 2 (11β-HSD1 and 11β-HSD2), TNF-α and IL-6 in the hypothalamus, prefrontal cortex (PFC) and spleen of 7-, 21- and 35-day-old piglets...
