[Morphology of the adrenal cortex in Cushing's syndrome].

Histological slides of the adrenals of 54 patients who underwent uni- or bilateral adrenalectomy for Cushing's syndrome at the Zürich University Hospital Department of urology between 1960 and 1977 were reexamined. In 29 patients (53.7%) Cushing's disease was due to diffuse bilateral adrenocortical hyperplasia, in 4 (7.4%) to micronodular cortical hyperplasia and in 3 (5.6%) to macronodular cortical hyperplasia and in 3 (5.6%) to macronodular hyperplasia. Two patients (3.7%) presented with primary bilateral nodular cortical dysplasia (so-called microadenomatosis). In 12 cases of Cushing's syndrome (22.2%) the basic lesion was a cortical adenoma and in 4 cases (7.4%) a cortical carcinoma. The histologic diagnoses corresponded well with biochemical findings, clinical diagnoses and further development of the disease. Histopathologic diagnosis of diffuse and micronodular hyperplasia presents no difficulties. Differential diagnosis of macronodular hyperplasia, cortical dysplasia, adenoma, and carcinoma may, however, be somewhat more problematic.

Cushing's syndrome due to bilateral adrenocortical adenomas with unique histological features.

Cushing's syndrome due to bilateral cortisol-secreting adenomas rarely occurs. We present a case of Cushing's syndrome due to bilateral adenomas. Both adenomas had distinct cell compositions, and were compared with emphasis on immunohistochemical and enzyme histochemical analysis for cytochrome P450(11beta) and 3beta-hydroxysteroid dehydrogenase (3betaHSD). A 37 year-old female was diagnosed with ACTH-independent Cushing's syndrome based on physical findings and hormonal evaluation. High-resolution CT scan showed bilateral adrenocortical adenomas and atrophied glands. 131I-methylnorcholesterol incorporation into both glands suggested both adenomas were functional. Clinical diagnosis prior to surgery was ACTH-independent Cushing's syndrome due to functioning bilateral adenomas. The left adrenal gland was totally resected, while the right one was partially resected by laparoscopic approach. Both adenomas were black on cut sections, and were comparatively evaluated by immunohistochemical and enzyme histochemical analysis for P450(11beta) and 3betaSD. The left adenoma was 1.6 cm in diameter and had a complex cellular composition and enzyme expression similar to that of primary pigmented nodular adrenocortical disease (PPNAD), while the right adenoma was 1.8 cm in diameter with compact cells typical of a solitary cortisol-producing adenoma. Adjacent bilateral adrenal cortex showed marked atrophy, but contained several micronodules. Serum cortisol levels, both at basal and after a low dodexamethasone, normalized thirteen months after surgery. In conclusion, the present case of Cushing's syndrome with bilateral adrenal adenomas demonstrated for the first time the simultaneous occurrence of two distinct adenomas, an ordinary cortisol-producing adenoma and a PPNAD-like adenoma. Further case reports of multiple adrenal adenomas should be well-analyzed to clarify whether the results from this case represent a new subgroup of ACTH-independent Cushing's syndrome.

Adrenal disorders of pregnancy.

In normal pregnancy, the maternal adrenal gland adapts to the physiologic changes necessary to sustain gestation. These changes protect the fetus and the mother, allowing for increased shunting of nutrients to the fetus and protection of immunologic rejection. The adrenal disorders pertinent to pregnancy include overactive and underactive secretion of adrenocortical hormones and tumors that secrete too much catecholamine. In addition, iatrogenic hypercortisolemia may be necessary to treat the mother for underlying diseases. The impact of iatrogenic hypercortisolemia on the fetus is addressed also.

Time course of 21-hydroxylase antibodies and long-term remission of subclinical autoimmune adrenalitis after corticosteroid therapy: case report.

Subclinical Addison's disease is characterized by the presence of adrenal autoantibodies (ACA) and steroid 21-hydroxylase autoantibodies (21OHAb) with or without adrenal function failure. In our previous longitudinal study some patients with high titers of ACA and at stage 2 of subclinical adrenocortical failure showed disappearance of ACA with recovery of normal adrenocortical function after corticosteroid treatment for Graves' ophthalmopathy. To investigate whether corticosteroid-induced modification of the adrenal autoimmune markers can also involve 21OHAb and to evaluate whether the remission of subclinical adrenocortical failure can persist over a long period of time, we followed-up for 100 months the levels of 21OHAb and ACA as well as the metabolic markers of adrenal function in one patient with Graves' ophthalmopathy and at stage 2 of subclinical adrenocortical failure before and after corticosteroid therapy. A 34-yr-old woman with Graves' disease and active ophthalmopathy who was found to be positive for ACA and to have high PRA, low aldosterone levels, and normal basal ACTH and cortisol levels, but impaired cortisol response to ACTH was studied. The patient was treated with oral corticosteroid therapy for 6 months. After corticosteroid therapy, 21OHAb, initially positive, became negative in concomitance with the disappearance of ACA and the restoration of normal adrenal function. The disappearance of both 21OHAb and ACA and their prolonged absence during the follow-up suggest that corticosteroid treatment can induce long-term remission of subclinical adrenal insufficiency and prevent the onset of the clinical phase of the disease. Our pilot study may pave the way to future trials aimed at preventing the onset of the clinical signs of Addison's disease in ACA/21OHAb-positive patients.

Primary pigmented nodular adrenocortical disease. A light and electron microscopic study of eight cases.

Primary pigmented nodular adrenocortical disease (PPNAD) is a rare cause of Cushing's syndrome, which is adrenocorticotropic hormone-independent and involves both adrenal glands. The characteristic pathological features include multiple pigmented cortical nodules and atrophy of the internodular cortex. The adrenal size ranges from small to normal or slightly enlarged. Review of the gross, light microscopic, and ultrastructural features of eight cases seen at the National Institutes of Health revealed several very unusual findings. We observed the following in our patients: macronodules up to 3.0 cm; microscopic foci of necrosis; mitoses; cortical hyperplasia rather than internodular atrophy; focal confluence of nodules giving a diffuse pattern of cortical involvement, and a focal trabecular growth pattern. The nodules were composed primarily of eosinophilic, lipid-poor cells similar to those of the zona reticularis. However, lipid-rich cells similar to those of the zona fasciculata were also demonstrated in the nodules by both light and electron microscopy. This suggests that the adrenal cortical nodules of PPNAD may be derived from not only the zona reticularis, but also the zona fasciculata.

A variant of adrenomyeloneuropathy with hypothalamic-pituitary dysfunction and neurologic remission after glucocorticoid replacement therapy.

Adrenomyeloneuropathy is a syndrome comprising spastic paraparesis, polyneuropathy, primary adrenocortical insufficiency and variable hypogonadism. We describe a 32 year old man who presented with contractures, peripheral neuropathy, primary adrenocortical insufficiency adn secondary hypogonadism. Abnormal responses of growth hormone, gonadotropins, prolactin and thyrotropin to provocative stimuli were found, without radiographic evidence of a pituitary or hypothalamic lesion. Almost complete recovery from the neurologic abnormalities occurred with glucocorticoid replacement therapy. The clinical features of this patient support a diagnosis of adrenomyeloneuropathy. The hypothalamic-pituitary dysfunction extends the clinical features of this patient support a diagnosis of adrenomyeloneuropathy. The hypothalamic-pituitary dysfunction extends the clinical spectrum of this disease. Remission of the paraparesis coincident with glucocorticoid replacement has not been reported previously.

Adrenalectomy for treatment of Cushing syndrome: results in 122 patients and long-term follow-up studies.

Patients with Cushing syndrome (n = 122) who underwent adrenalectomy from 1957 through 1993 were reviewed for survival and complications. Of the 122 patients, 70 had adrenocortical adenoma, 30 Cushing's disease, 6 primary pigmented nodular adrenocortical disease (PPNAD), 7 other types of primary nodular hyperplasia, 5 adrenocortical carcinoma, and 4 ectopic ACTH syndrome. Sixty-five patients with adrenocortical adenoma are alive, and the survival rate was equal to the age-matched control population, when patients who died of the postoperative complication were excluded. Of the patients with Cushing's disease, 20 are alive; and 10 of 16 patients (63%) who were followed-up and evaluated had skin pigmentation. Four of sixteen patients (25%) developed Nelson's syndrome. Four PPNAD patients and five with other types of nodular hyperplasia are alive. Most of these patients underwent bilateral total adrenalectomy, but some patients remitted after unilateral adrenalectomy. All of five adrenocortical carcinoma patients and four with ectopic ACTH syndrome died within 2 years after operation. The prognosis for patients with adrenocortical adenoma after unilateral adrenalectomy is excellent, though it is important to avoid operative complications. The rapid cure of signs and symptoms of glucocorticoid excess after total adrenalectomy is ensured, and prognosis is satisfactory under careful glucocorticoid replacement, making total adrenalectomy an alternative treatment for Cushing's disease.
