We investigated the mechanism of dissociation of cortisol and dehydroepiandrosterone sulfate (DHEA-S) secretion by the adrenal glands after the removal of an adrenal gland containing an adrenocortical adenoma in a patient with Cushing's syndrome. After removal of the adrenocortical adenoma, the serum cortisol rapidly decreased from 24.6 +/- 6.4 micrograms/dl (mean +/- SD, n = 6) to 0.7 +/- 0.5 ...
Adrenal rest tumor in liver is a very rare tumor. It originates from an adrenal rest, which is derived from the aberrant adrenocortical tissue. Adrenal rest tumor is an ectopic collection of adrenocortical cells in extra-adrenal sites. This tumor may be hormonally active and manifest endocrine syndromes. But, most tumors are non-functioning and benign. Histologically, hepatic adrenal rest tumor...
Carney complex is a multiple neoplasia syndrome, inherited in an autosomal dominant manner, that is characterized by lentigines, cardiac myxoma, and numerous endocrine and other tumors, including primary pigmented nodular adrenocortical disease. Here, we describe a typical case of Carney complex in a 27-year-old female who exhibited spotty skin pigmentation on the lips, oral mucosa, fingers, an...
GIP-dependent Cushing's syndrome is caused by ectopic expression of glucose-dependent insulinotropic polypeptide receptor (GIPR) in cortisol-producing adrenal adenomas or in bilateral macronodular adrenal hyperplasias. Molecular mechanisms leading to ectopic GIPR expression in adrenal tissue are not known. Here we performed molecular analyses on adrenocortical adenomas and bilateral macronodula...
Adrenal tumors showing no clinical manifestations (incidentaloma) are frequently encountered during imaging analysis upon routine examinations. These tumors are sometimes associated with hypertension and/or diabetes mellitus (DM). We have examined six cases of incidentalomas with these symptoms in this study. All patients underwent endocrinological evaluation by measuring plasma cortisol and al...
INTRODUCTION Primary pigmented nodular adrenocortical disease is a rare cause of adrenocorticotropic hormone-independent Cushing's syndrome. We report an uncommon primary pigmented nodular adrenocortical disease case presenting with a unilateral adrenocortical nodule and provide a brief overview of the existing literature. CASE PRESENTATION A 27-year-old Caucasian woman was admitted to our De...
Adrenocortical tumour have been described in patients with 21-hydroxylase deficiency. These tumours are usually considered to be ACTH – dependent, as diffuse adrenal cortical hyperplasia is commonly seen. We report adrenal cortical tissue tumours developed in three patients with untreated congenital adrenal hyperplasia due to 21-hydroxylase deficiency. All of them had symptoms of adrenogenital ...
An adrenocortical adenoma causing Cushing's syndrome (Cushing's adenoma) produces a unilateral concordant visualization (UCV) imaging pattern in which the adenoma is only visualized on radioiodocholesterol adrenocortical scintigraphy. But because this imaging pattern is also noted in some patients with adrenal incidentalomas, we examined whether the UCV-incidentaloma was essentially identical w...
To a further understanding of the role of steroid hormones in adrenal disorders, we have prepared free cell system of adrenal cells, using adrenal tissues thai had been removed by operation from (i) cases of Cushing's syndrome due to adrenocortical adenoma or adrenocortical hyperplasia, (ii) a case of primary aldosteronism, and (iii) a patient with virilizing adrenal tumor. Twelve important ste...
