Adrenocorticotropic hormone production by pancreatic neuroendocrine tumor (PNET) is rare and results in hyperstimulation of the adrenal gland to produce ectopic Cushing syndrome. Our case showcases the safety and effectiveness of percutaneous CT-guided microwave ablation of the adrenal gland in a 49-year-old female with PNET and hepatic metastases who presented with ectopic Cushing syndrome despite surgical resection of the primary pancreatic tumor and left adrenal gland. Prior to ablation, the right adrenal gland measured 4...

Paragangliomas are tumors that originate from the extra-adrenal chromaffin and nonchromaffin cells of neural crest origin. Lymph node metastases are common, while distant metastases to lung, liver, and bone are rare events and usually occur in the presence of a long standing clinically evident primary tumor. Primary diagnosis of paraganglioma at a metastatic site without a known primary is a diagnostic challenge. We report a case of an adult woman with incidentally detected metastasis to bilateral lungs from an occult carotid body paraganglioma, which presented a cytopathological diagnostic dilemma on EBUS-TBNA from paratracheal lymph nodes...

BACKGROUND: Ultrasonography to visualize adrenal gland lesions and evaluate incidentally discovered adrenal masses in dogs has become more reliable with advances in imaging techniques. However, correlations between sonographic and histopathological changes have been elusive. The goal of our study was to investigate which ultrasound features of adrenal gland abnormalities could aid in discriminating between benign and malignant lesions. To this end, we compared diagnosis based on ultrasound appearance and histological findings and evaluated ultrasound criteria for predicting malignancy...

Thyroid metastases from lung cancer are very rare. A woman aged 42 years with a tumour in the lower lobe of the right lung was diagnosed as having lung adenocarcinoma positive for echinoderm microtubule-associated proteinlike 4-anaplastic lymphoma kinase. Positron emission tomography demonstrated fluorodeoxyglucose accumulation in the lower lobe of the right lung, the right thyroid lobe and both adrenal glands. We performed fine-needle aspiration biopsy (FNAB) and used reverse transcriptase-PCR (RT-PCR) to diagnose the patient as having metastatic lung adenocarcinoma to the thyroid gland...

Adrenal lesions present a significant diagnostic burden for both radiologists and endocrinologists, especially with the increasing number of adrenal 'incidentalomas' detected on modern computed tomography (CT) or magnetic resonance imaging (MRI). A key objective is the reliable distinction of benign disease from either primary adrenal malignancy (e.g., adrenocortical carcinoma or malignant forms of pheochromocytoma/paraganglioma (PPGL)) or metastases (e.g., bronchial, renal). Benign lesions may still be associated with adverse sequelae through autonomous hormone hypersecretion (e...

Metastasis to the tongue, duodenum or pancreas from primary lung cancer is uncommon. Primary lung cancer presenting with symptoms related to metastases at these sites, at initial presentation is extremely rare. We report a 45-year-old man with disseminated lung malignancy who presented with dyspepsia, melena, symptoms due to anaemia and swelling in the tongue. Oral examination revealed a hard submucosal anterior tongue lesion. Biopsies from the tongue lesion and the duodenal ulcer seen on upper gastrointestinal endoscopy were suggestive of metastasis from lung primary...

BACKGROUND: We wanted to assess the efficacy of curative intent pulmonary resection for non-small cell lung cancer (NSCLC) patients with synchronous M1b-distant metastases in a single organ or lesion. METHODS: Between 1995 and 2015, 23 consecutive synchronous M1b-cStage IV NSCLC patients who underwent any treatment for metastases and curative intent pulmonary resection were retrospectively analyzed. RESULTS: Sixteen patients were men and 7 were women, with a median age of 56 years (range: 41 to 76 years)...

A rare neuroendocrine tumor, the pheochromocytoma (PCC) raises problems due both the limited experience of the researchers in this field and its pathogenic mechanisms, still not fully elucidated. The malignant potential of this tumor cannot be predicted based on its macro- or microscopic aspects, but on the presence of metastases. The aims of this study were: (1) the reevaluation of data for a pertinent and complete tumor diagnostic and prognostic pattern; (2) the statistical correlation of all investigated parameters with the malignant form and the survival rate in order to obtain a possible predictor of malignancy; (3) the potential identification of initially diagnosed benign tumors that become malignant in time...

Peripheral neuroblastic tumours (PNTs), a family of tumours arising in the embryonal remnants of the sympathetic nervous system, account for 7-10% of all tumours in children. In two-thirds of cases, PNTs originate in the adrenal glands or the retroperitoneal ganglia. At least one third present metastases at onset, with bone and bone marrow being the most frequent metastatic sites. Disease extension, MYCN oncogene status and age are the most relevant prognostic factors, and their influence on outcome have been considered in the design of the recent treatment protocols...

Objective Image guided thermal ablation of adrenal metastases has been increasingly used for local tumor control. This procedure has been associated with hypertensive urgency; however endocrine complications have not been clearly described. Our objective was to assess the hemodynamic behavior and risk for adrenal insufficiency related to adrenal ablation. Additionally, we sought to understand the utility of preprocedural α-blockade to prevent peri-procedural hemodynamic complications. Methods This is a retrospective study of patients undergoing image guided ablation of adrenal metastases between 2003 and 2015 at our institution...

Soluble pulmonary factors have been reported to be capable of inhibiting the viability of cancer cells that metastasize to the lung, but the molecular identity was obscure. Here we report the isolation and characterization of the beta subunit of hemoglobin as a lung-derived anti-metastatic factor. Peptide mapping in the beta subunit of human hemoglobin (HBB) defined a short C-terminal region (termed Metox) as responsible for activity. In tissue culture, both HBB and murine HBB2 mediated growth arrest and apoptosis of lung-metastasizing neuroblastoma cells, along with a variety of other human cancer cell lines...

Skin is an uncommon site for metastasis with only 0.7-9% of all patients with cancer being affected when compared to other organs. Generally, the time lag between the diagnosis of primary malignancy and the recognition of the skin metastases is long, but sometimes these metastases may be the first indication of otherwise clinically silent visceral malignancies as seen in our case. In cholangiocarcinomas, the occurrence of cutaneous metastases is extremely rare. Their most common sites of metastasis are visceral organs i...

FDG PET/CT has high sensitivity and specificity for the detection of distant metastases from cutaneous melanoma. Imaging is recommended for patients with clinical suspicion of metastasis and should be considered for those with confirmed sentinel lymph node metastasis. Metastatic melanoma bears a poor prognosis. Only a complete resection improves survival, which explains the need to detect potentially unresectable disease, and most metastatic patients are ineligible for a curative surgical procedure. Here, FDG PET/CT demonstrated isolated bilateral adrenal metastases from melanoma of unknown primary...

Renal cell carcinoma metastases to pancreas, thyroid, and contralateral adrenal gland are decidedly uncommon. Clear cell renal cell carcinoma (CCRCC) is the most frequent subtype. Cytology diagnosis may be challenging. A 74-year-old male with remote history of vocal cord malignancy and hypertension presented with abdominal pain. Computed tomography (CT) revealed 8.4 cm left renal mass highly suspicious for renal cell carcinoma, a 1.8 cm mass within vessels near left adrenal and a 2.5 cm mass in pancreatic tail...

Kaposi sarcoma (KS), a vascular tumor caused by infection with human herpesvirus 8 (HHV8), is a systemic disease that can present with cutaneous lesions with or without visceral involvement. Very few cases of KS, most of which were associated with AIDS, have been reported in the adrenal gland. Anaplastic transformation of KS is a rare clinical presentation known as an aggressive disease with local recurrence and metastatic potential. We report here a 47-year-old HIV negative male presented with extra-adrenal symptoms and had an incidentally detected anaplastic adrenal KS exhibited aggressive clinical course...

Multiple Endocrine Neoplasia (MEN) is a condition in which several endocrine organs of an individual are affected by adenoma, hyperplasia and less often carcinoma, either simultaneously or at different stages of life. Two existing syndromes, MEN1 and MEN2 (2A, 2B), in literature is also mentioned MEN4, are associated also with other non-endocrine disorders. MEN1 (Wermer syndrome) affects the pituitary, parathyroid, and pancreatic area. 95 % of patients show very early manifestation of hyperparathyroidism, often before 40 years of age...
