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...

Transitional cell carcinoma (TCC) urinary bladder is known to metastasize to regional lymph nodes (LNs), liver, lung, bone, adrenal glands, and intestine. However, an asymptomatic TCC bladder manifesting as metastatic axillary LN mass and extensive retroperitoneal lymphadenopathy is rarely heard of. A 46-year-old male, smoker, presented with 8 cm × 6 cm right axillary swelling of 1-month duration. Aspiration cytology revealed metastatic deposits of poorly differentiated carcinoma favoring TCC. Metastatic evaluation with (18)F-fluorodeoxyglucose positron emission tomography ((18)FDG-PET) scan showed mass lesion urinary bladder, conglomerate right axillary mass and extensive retroperitoneal LNs with significant metabolic activity, biopsy from which revealed deposits of TCC...

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...

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...

Introduction: Diagnosis of adrenal crisis and panhypopituitarism in patients with septic shock is difficult but crucial for outcome. Case: A 66-year-old woman with metastasized breast cancer presented to the ED with respiratory insufficiency and septic shock after a 2-day history of the flu. After transfer to the ICU, corticosteroids were started in addition to antibiotics, as the patient was vasopressor-nonresponsive. Diabetes insipidus was diagnosed due to polyuria and treated with 4 mg desmopressin...

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%)...

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...

The possibility of bilateral adrenal gland metastasis from renal cell carcinoma (RCC) has been extremely rarely reported. Surgery may be the preferred treatment strategy for adrenal metastasis from RCC. In this article, we present a patient with bilateral large adrenal metastases from the left RCC, which was managed with simultaneous bilateral laparoscopic excision. A 64-year-old woman had undergone left adrenal sparing radical nephrectomy for a left RCC 7 years ago. Her abdominal CT scan revealed bilateral large adrenal metastasis...

Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver, and extrahepatic metastases are typically found during disease progression. The incidence of adrenal metastasis (AM) from HCC in autopsy series ranges from 4.6 to 12.5%, and it is the second most common site of metastasis after the lungs. To date, there have been few reports of patients who underwent adrenalectomy for isolated AM from HCC after liver transplantation (LT). A woman aged 55 years was referred to our clinic for the evaluation of a right adrenal mass that was detected by abdominal ultrasonography at another center...

Carney triad is a very rare syndrome characterized by the synchronous or metachronous occurrence of gastrointestinal stromal tumors, pulmonary chondroma, and extra-adrenal paraganglioma. We present the case of a 36-year-old woman with complete Carney triad who underwent a Ga-DOTA-TATE PET/CT scan for restaging of metastasizing extra-adrenal paraganglioma and for evaluation of targeted radionuclide therapy potential. On the Ga-DOTA-TATE PET scan, increased tracer accumulation was observed in paraganglioma metastases...

We developed a model of experimental melanoma. Intralienal xenogeneic transplantation of a suspension of melanoma cells B16 in physiological saline (0.1 ml; 1:10) was conducted to outbred male rats. In 6 months, histologically confirmed melanoma B16 in the spleen and its metastases in the liver, intestine, pancreas, adrenal glands, and lungs (hematogenous metastasis), as well as in the thymus and lymph nodes (lymphogenous metastasis) were revealed in rats. The proposed rat model of melanoma B16 metastasizes by the hematogenous and lymphogenous pathways, develops over 6 months, and allows receiving sufficient volume of material for analysis...

Adrenal collision tumors (ACTs), in which distinct tumors coexist without histological intermingling in the same adrenal gland, are rare and their actual prevalence is unknown. ACTs commonly consist of adrenal cortical adenoma, myelolipoma, or metastatic malignant tumor. We report a 58-year-old woman with a past history of breast cancer, who presented with a 1 month history of fevers, chills, and abdominal fullness. The physical examination and the laboratory data including endocrine studies were unremarkable...

Although extrahepatic metastases from hepatocellular carcinoma (HCC) are present in only 5-15% of cases, they are certainly factors associated with poor prognosis. The main sites include lung, lymph nodes, bones, and adrenal glands, in descending order. Metastasis in the central nervous system is extremely rare, and the incidences vary from 0.6 to 1.7%. We report a case of a 54-year-old man previously diagnosed with alcohol-induced cirrhosis of the liver and HCC. The patient was admitted presenting progressive left hemiparesis and headache which started 2 days earlier, with no history of cranioencephalic trauma...

With the widespread use of 2-deoxy-2-((18)F) fluoro-D-glucose positron emission tomography-computed tomography (FDG PET/CT) in oncologic imaging, it has become increasingly important for physicians who interpret FDG PET/CT scans to confidently recognize the spectrum of incidentally encountered benign and malignant findings. The adrenal glands represent an interesting nexus of multiple rare and common benign intrinsic tumors as well as metastases from a variety of primary malignancies. Given the breadth of adrenal gland pathology, careful description of the FDG PET/CT appearance of these pathologies is of value to help reduce misinterpretation...

Prostate cancer (PC) remains a leading cause of cancer-related deaths among men worldwide, despite continuously improved treatment strategies. Patients with metastatic disease are treated by androgen deprivation therapy (ADT) that with time results in the development of castration-resistant prostate cancer (CRPC) usually established as metastases within bone tissue. The androgen receptor (AR) transcription factor is the main driver of CRPC development and of acquired resistance to drugs given for treatment of CRPC, while a minority of patients have CRPC that is non-AR driven...

Little is known about the natural history of cancer and its evolution to metastasis. Paget was the first to postulate the important role played by microenvironment in metastasis progression. Since, the concept of his "seed and soil" theory has been supported and confirmed. Understanding the chronology and natural course that underlie metastasis is mandatory to deepen this concept and to progress in the development of novel therapeutic strategies. A total of 413 patients who underwent treatment for brain metastasis (2013-2016) were included...

Synchronous multiple endocrine gland metastasis caused by small cell lung cancer (SCLC) is rare. A patient was investigated for primary cancer because of suspected brain metastasis on computed tomography (CT). Baseline (18) F-fluorodeoxyglucose (FDG) positron emission tomography (PET)-CT was positive in the lung and multiple endocrine glands (right thyroid, right breast, pancreatic body, right adrenal gland, and left ovary). Histopathology confirmed small cell lung cancer. The patient's symptoms were alleviated after chemotherapy and brain radiotherapy...
