The functional spectrum of adrenocortical adenomas

Medical Hypotheses, 1993
Adrenocortical adenomas (ACA) are frequently discovered at autopsy. Nowadays, modern radiologic techniques incidentally uncover the usually silent ACA during lifetime. On the basis of various reports and the results of endocrine tests, i.e. dexamethasone suppression (DST) and CRH response, we characterize 3 major types of functioning ACA.

Symptomatic Intraspinal Oncocytic Adrenocortical Adenoma

Endocrine Pathology, 2008
Most intraspinal neoplasms of epithelial origin are metastases from primary carcinomas. Benign epithelial tumors are rarely found at this site. We here present the case of a 44-year-old woman with a lesion in the cauda equina that fulfilled the radiologic criteria of schwannoma and caused clinical symptoms for 3 years. The excised tumor was composed of

ADRENOCORTICAL ADENOMA WITH PRIMARY ALDOSTERONISM IN CULTURE

Acta Pathologica Japonica, 1986
Four adrenocortical adenomata with primary aldosteronism (Conn's adenomata) were examined by light and electron microscopy employing cell culture methods. Unstimulated cells existed as a unit of the clusters, but Conn's ademona cells reacted to ACTH. The cultured cells produced mostly cortisol under ACTH‐stimulation as time passed.

VIRILIZING ADRENOCORTICAL ADENOMA RESPONSIVE TO GONADOTROPHIN

Acta Endocrinologica, 1975
ABSTRACT A virilizing adrenocortical adenoma was demonstrated in a young female. Urinary 17-ketosteroid excretion and subfractions, plasma testosterone level and urinary 17-ketogenic steroid excretion were markedly increased. Dehydroepiandrosterone was the main constituent of the androgen excess.

Fine Structure of a Virilizing Adrenocortical Adenoma

Beiträge zur Pathologie, 1976
An adrenocortical adenoma associated with adrenogenital syndrome in a two-year-old boy was investigated light and electron microscopically. Urinary 17-ketosteroid excretion was considerably elevated and unresponsive to dexamethasone administration. The level returned to normal after surgical removal of the tumour.

ADRENOCORTICAL ADENOMA WITH CUSHING'S SYNDROME IN CULTURE

Acta Pathologica Japonica, 1986
Two adrenocortical adenomata with Cushing's syndrome were examined employing cell culture methods. The results revealed that the clear‐type cells changed into compact‐type cells, and that the compact cells played a role in the production and secretion of steroid hormones. Furthermore, it is likely that they underwent fragmentation and produced collagen

Mutational landscape of non-functional adrenocortical adenomas

Endocrine-Related Cancer, 2022
Adrenal incidentalomas are the most frequent human neoplasms. Recent genomic investigations on functional adrenocortical tumors have demonstrated that somatic mutations in PRKACA and KCNJ5 responsible for the development of adrenocortical adenomas (ACAs)

Calcified aldosterone-producing adrenocortical adenoma

Clinical Imaging, 1996
We report the first case of benign aldosteronoma of an ordinary size with calcifications. We review the clinical, clinical imaging, histopathological, and laboratory features of aldosterone-producing adrenal adenoma versus carcinoma. We conclude that no single feature is diagnostic, and the full range of data must be considered.

Cecal perforation and adrenocortical adenoma in a dog

Journal of the American Veterinary Medical Association, 1987
Cecal perforation was diagnosed in a dog with a history of acute vomiting. The dog also had an adrenocortical adenoma. Intestinal perforation can be a serious complication of cortico-steroid treatment in the dog, but has not been attributable to hyperadrenocorticism.

Myxoid adrenocortical adenoma with a pseudoglandular pattern

Virchows Archiv, 2004
Myxoid changes rarely occur in adrenocortical adenomas and carcinomas. Only eight benign tumours with such features have been described thus far, five of which also had a prominent pseudoglandular component. We report an additional pseudoglandular myxoid adenoma of the adrenal gland detected in a 58-year-old male patient who developed mild hypertension.
