Aldosterone and cortisol, the main mineralocorticoid and glucocorticoid hormones in humans, are produced in the adrenal cortex, which is composed of three concentric zone with specific functional characteristics. Adrenocortical adenomas (ACA) may lead to the autonomous secretion of aldosterone responsible for primary aldosteronism, the most frequent form of secondary arterial hypertension. In the case of cortisol production, ACA lead to overt or subclinical Cushing syndrome. Genetic analysis driven by next generation sequencing technology has enabled the discovery, during the last seven years, of the genetic causes of a large subset of ACA...

Unilateral adrenal metastases without disseminated disease has rarely been reported in differentiated thyroid carcinoma (DTC). A 72-year-old female presented with vague abdominal discomfort and loss of appetite of 2 months duration. She had undergone left hemithyroidectomy for a benign thyroid nodule 18 years ago. A contrast CT of the abdomen showed a large left adrenal mass measuring 11×9 cm, suspicious of adrenocortical carcinoma. Hormonal evaluation was in keeping with a non-functional tumour. The patient underwent left adrenalectomy, histopathology of which revealed metastatic well-differentiated thyroid carcinoma...

BACKGROUND: Medullary thyroid carcinoma (MTC) is a rare disease. Treatment options for recurrent disease are limited. Somatostatin analogues might have a role as anticancer agents agents in MTC, although the evidence is inconclusive. PATIENT FINDINGS: A 64-year old male was diagnosed with MTC in January 2010. Total thyroidectomy with neck dissection (stage IVA, pT2pN1bM0, R1) was performed, followed by adjuvant locoregional radiotherapy. Two years later, the patient developed recurrent metastatic disease evidenced by elevated carcinoembryonic antigen (CEA) and calcitonin levels, and a positive uptake (Octreoscan®) in the right adrenal gland and pancreatic head...

Carney Complex (CNC) is a multiple neoplasia syndrome characterized by skin tumors and pigmented lesions, myxomas, and various endocrine tumors. The aim of this case report was to describe a case of CNC with a novel PRKAR1A mutation. A man aged 46 years with a medical history of surgery for cardiac myxomas at the age of 39 was admitted to our hospital because of four newly-developed heart masses. The histologic examination confirmed cardiac myxomas. He had many presentations of CNC such as growth hormone (GH) and prolactin (PRL)-secreting mixed pituitary adenoma, benign thyroid nodule, large-cell calcifying Sertoli cell tumor (LCCST), and superficial angiomyxoma...

Malignant feminizing adrenocortical tumors are exceedingly rare. Their main presentation is gynecomastia. In these estrogen secreting tumors (with or without other adrenocortical hormones) lack of gynecomastia is exceptional as in our case. A 44-year-old man presented with abdominal pain. Radiological assessment revealed a tumor measuring 120 × 95 mm in the retroperitoneal area with numerous metastases. Pathological examination pleaded for an adrenal origin with a Weiss's score of 5. Six months later, the tumor relapsed, and he had a second surgery and was sent for hormone assessment...

BACKGROUND: Gangliocytic paraganglioma (GP) is a rare neuroendocrine neoplasm, which occurs mostly in the periampullary portion of the duodenum; the majority of the reported cases of duodenal GP has been of benign nature with a low incidence of regional lymph node metastasis. GP arising from the pancreas is extremely rare. To date, only three cases have been reported and its clinical characteristics are largely unknown. CASE PRESENTATION: A nodule located in the pancreatic head was incidentally detected in an asymptomatic 68-year-old woman...

Paragangliomas are rare neoplasms that arise from chromaffin cells of the sympathetic and parasympathetic nervous system. These tumors are often cured by surgical resection but the risk for metastatic disease exists, particularly for extra-adrenal paragangliomas. The behavior of these tumors is unpredictable, and clinical and histopathological features associated with malignancy have not been determined. The most common sites of metastases include local and distant lymph nodes, bone, liver, and lung. Cutaneous metastases are exceedingly rare with only 2 reported cases, both of which presented on the scalp...

BACKGROUND: Colloid adenocarcinoma of the lung is a rare subtype of variants of invasive adenocarcinomas. We report the appearance of this unusual entity on (18)F-fluorodeoxyglucose positron emission tomography/computed tomography. CASE PRESENTATION: A 60-year-old man of Chinese Han nationality coughed with a little white sputum for 1 month. Chest computed tomography showed multiple bilateral subpleural nodules and plaques accompanied by air bronchograms, which were most concentrated in the lower lobe of his right lung...

Anaplastic thyroid cancer is the rarest tumour of the thyroid gland, representing only 2% of clinically recognised thyroid cancers. The most common metastatic sites are lungs, followed by the intrathoracic and neck lymph nodes. We report the case of a 62-year-old woman who presented to our setting with multiple soft tissue nodules, thyroid mass, head swelling and weight loss. Radiological investigation showed a large thyroid mass with widespread metastasis in subcutaneous tissues of both upper limbs, chest and abdomen...

The participation of aberrant receptors and intra-adrenal ACTH in hyperplastic tissue are considered mechanisms that regulate hypercortisolism in PMAH. Additionally, germline ARMC5 mutations have been described as the most frequent genetic abnormality found in patients diagnosed with PMAH. Previous functional studies analyzed ARMC5 role using H295R cells. Therefore, we investigated the role of ARMC5 in cell cultures obtained from PMAH nodules containing steroidogenic cells, aberrant receptors and intra-adrenal ACTH...

Pheochromocytomatosis, a very rare form of pheochromocytoma recurrence, refers to new, multiple, and often small pheochromocytomas growing in and around the surgical resection bed of a previous adrenalectomy for a solitary pheochromocytoma. We here report a case of pheochromocytomatosis in a 70-year-old female. At age 64 years, she was diagnosed with a 6-cm right pheochromocytoma. She underwent laparoscopic right adrenalectomy, during which the tumor capsule was ruptured. At age 67 years, CT of abdomen did not detect recurrence...

We describe gross, histopathological, and immunohistochemical features of Streptococcus phocae and cetacean morbillivirus coinfection in a short-beaked common dolphin Delphinus delphis. Major gross findings were cutaneous purulent nodules in the tail fluke, vegetative mitral valve endocarditis, and presumed postpartum pyometra. Histologic examination revealed bacterial septicemia characterized by widespread intravascular coccoid bacterial emboli. These were associated with fibrinonecrotizing to pyogranulomatous dermatitis and panniculitis, embolic pneumonia, neutrophilic and lymphoplasmacytic meningochoroiditis, random neutrophilic hepatitis, lymphoplasmacytic myocarditis and epicarditis, necrotizing adrenalitis, suppurative endometritis, and multicentric reactive lymphadenopathy...

Extract of pine nodules (matsufushi) formed by bark proliferation on the surface of trees of Pinus tabulaeformis or Pinus massoniana has been used as an analgesic for joint pain, rheumatism, neuralgia, dysmenorrhea and other complaints in Chinese traditional medicine. Here we report the effects of matsufushi extract and its components on catecholamine secretion and synthesis in cultured bovine adrenal medullary cells. We found that matsufushi extract (0.0003-0.005%) and its component, SJ-2 (5-hydroxy-3-methoxy-trans-stilbene) (0...

RATIONALE: The U.S. Preventive Services Task Force recommends lung cancer screening with low-dose chest computed tomographic scans (LDCT) for a well-defined high-risk population. Data on the frequency and impact of incidental findings (IFs) based on LDCT scans performed within a centralized lung cancer screening program have not been reported. OBJECTIVES: Researchers in previous studies have reported IFs in the setting of clinical trials. We present our findings in a real clinical setting where the decision to manage these findings may depend on factors that are not captured in a research trial such as disclosing IFs, patient preferences, severity of comorbidities, and physician expertise...

Cushing's syndrome is rare in childhood and is usually caused by a pituitary adenoma. Primary hyperfunction of adrenal glands is less frequent, particularly primary pigmented nodular adrenocortical disease (PPNAD). It occurs usually in children and adolescents, with female preponderance, while Cushing's disease has increased frequency in prepubertal males. A case of a 6-year-old boy is presented with isolated non-familiar PPNAD. The clinical pattern involved Cushingoid appearance, hypertension, virilization and depressive mood...

Context: Approximately half of patients with primary aldosteronism (PA) have clinically evident disease according to clinical (hypertension) and/or laboratory (aldosterone and renin levels) findings but do not have nodules detectable in routine cross-sectional imaging. However, the detailed histopathologic, steroidogenic, and pathobiological features of cross-sectional image-negative PA are controversial. Objective: To examine histopathology, steroidogenic enzyme expression, and aldosterone-driver gene somatic mutation status in cross-sectional image-negative hyperaldosteronism...

A Cavalier King Charles Spaniel dog was presented because of a 10-d history of progressive vomiting, inappetence, and lethargy, with mild neurologic signs. Fine-needle aspirates of splenic nodules seen on ultrasound were suggestive of a carcinoma. On autopsy, a disseminated neoplasm was present in the lung, spleen, and adrenal glands. Additionally, there was a Chiari-like malformation of the skull with corresponding syringomyelia of the cranial spinal cord. Histologically, the neoplasm was comprised of a pleomorphic population of round cells with a high mitotic rate...
