1/6. Excessive concern with physical appearance leading to a diagnosis of adrenal adenoma.We report an unusual case of Cushing's syndrome manifested by anxiety over body image in a 26-year-old nurse. Initial presentation was a 'dermatological non-disease'. Clinical signs became increasingly evident during the course of the disease, justifying an adrenal gland evaluation which showed a secreting adrenocortical adenoma. Surgical treatment led to recovery with return to normal appearance and cessation of her aesthetic complaints. Our observation shows that persistent aesthetic complaints may sometimes reveal early hypercorticism.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/6. Functioning adrenal black adenoma with pulmonary and cutaneous cryptococcosis: a case report and review of English literature.A 53-year-old woman experienced progressive general weakness and lumbago in the 2 years prior to a physical examination which disclosed cushingoid manifestations and a skin ulcer on the back of her right knee joint. Her plasma cortisol concentration ranged from 24.7 to 31.1 microg/dl, with an ACTH level <5 pg/ml. Urinary excretions of 17-hydroxycorticosteroid (17-OHCS) and 17-ketosteroid (17-KS) were 20.5 mg/day and 5.1 mg/day, respectively, and urinary cortisol was also increased (421 microg/day). Cortisol was not suppressed after the administration of 8 mg dexamethasone. Abdominal ultrasound sonography, computed tomography (CT) scan, and magnetic resonance imaging (MRI) studies demonstrated a left adrenal tumor and further, a chest X-ray examination showed a cavitary lesion containing a fungus ball-like mass in the left lower lung field. The serum cryptococcal antigen titer was positive at 1:128 and a bronchoalveolar lavage fluid culture yielded a growth of cryptococcus neoformans. A biopsy specimen of the skin ulcer also suggested cryptococcosis. As a result, a left adrenectomy was performed, and the excised specimen was shown to be an adenoma consisting of compact cells with abundant pigmentation (black adenoma). A diagnosis of functioning black adenoma of the adrenal gland, complicated with pulmonary and cutaneous cryptococcosis was made.- - - - - - - - - - ranking = 3.0980349654632keywords = physical examination, physical (Clic here for more details about this article) |
3/6. Myxoid adrenal cortical adenoma.Myxoid adrenal cortical adenoma is a rare tumor and, to our knowledge, only 16 cases have been reported. We present the case of a 56-year-old Japanese man who was admitted to hospital because of a right adrenal mass that was discovered during a routine physical examination. The resected mass was well circumscribed and contained canary yellow multinodular regions that were surrounded by a brown gelatinous region. Histologically, the multinodular regions resembled a conventional adrenal cortical adenoma, being composed of solid aggregates of large clear or eosinophilic cells. In the gelatinous region, anastomosing small eosinophilic or vesicular cells were visible within a myxoid stroma that contained large amounts of acidic mucopolysaccharides. light-microscopic findings were consistent with a diagnosis of adenoma. Immunohistochemical staining revealed that a small number of tumor cells were positive for vimentin, and the MIB-1 labeling index was less than 1%. flow cytometry demonstrated that cells were diploid. At the ultrastructural level, many fat droplets were found in the large clear cells in the multinodular regions. Small eosinophilic cells in the myxoid region contained many mitochondria but few fat droplets. There were no findings suggestive of malignancy. Although the adrenal cortex might have the potential to produce connective tissue-type mucin as a consequence of its mesodermal origin, the mechanism of production of acidic mucopolysaccharides in a myxoid adrenal cortical tumor remains to be clarified.- - - - - - - - - - ranking = 3.0980349654632keywords = physical examination, physical (Clic here for more details about this article) |
4/6. 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.- - - - - - - - - - ranking = 0.25keywords = physical (Clic here for more details about this article) |
5/6. A case of aldosterone-producing adrenocortical adenoma associated with a probable post-operative adrenal crisis: histopathological analyses of the adrenal gland.We describe a case of aldosterone-producing adrenocortical adenoma (APA) associated with a probable post-operative adrenal crisis possibly due to subtle autonomous cortisol secretion. The patient was a 46-year-old female who suffered from severe hypertension and hypokalemia. CT and MRI scans revealed a 2-cm diameter adrenal mass. The patient's plasma aldosterone level was increased, and her plasma renin activity was suppressed, both of which findings were consistent with APA. Cushingoid appearance was not observed. Morning and midnight serum cortisol and plasma adrenocorticotropic hormone (ACTH) levels were all within the normal range. Her serum cortisol level was suppressed to 1.9 microg/dl as measured by an overnight 1-mg dexamethasone suppression test, but was incompletely suppressed (2.7 microg/dl) by an overnight 8-mg dexamethasone suppression test. In addition, adrenocortical scintigraphy showed a strong uptake at the tumor region and a complete suppression of the contra-lateral adrenal uptake. After unilateral adrenalectomy, she had an episode of adrenal crisis, and a transient glucocorticoid replacement improved the symptoms. Histopathological studies demonstrated that the tumor was basically compatible with APA. The clear cells in the tumor were admixed with small numbers of compact cells that expressed 17alpha-hydroxylase, suggesting that the tumor was able to produce and secrete cortisol. In addition, the adjacent non-neoplastic adrenal cortex showed cortical atrophy, and dehydroepiandrosterone sulfotransferase immunoreactivity in the zonae fasciculata and reticularis was markedly diminished, suggesting that the hypothalamo-pituitary-adrenal (HPA) axis of the patient was suppressed due to neoplastic production and secretion of cortisol. Together, these findings suggested that autonomous secretion of cortisol from the tumor suppressed the HPA axis of the patient, thereby triggering the probable post-operative adrenal crisis. Post-operative adrenocortical insufficiency should be considered in clinical management of patients with relatively large APA, even when physical signs of autonomous cortisol overproduction are not apparent.- - - - - - - - - - ranking = 0.25keywords = physical (Clic here for more details about this article) |
6/6. Congenital adrenocortical adenoma: case report and review of literature.Congenital ardrenocortical neoplasms are exceedingly rare. Our review of the medical literature revealed 23 reported cases of adrenocortical neoplasm including this one. Eighteen of these cases were adrenocortical carcinoma and four were grouped as adrenocortical tumor. We have not found any reported case with a histological diagnosis of a congenital adrenocortical adenoma. We present this case of a congenital adrenocortical neoplasm with histological findings consistent with an adrenocortical adenoma in a premature infant aged 27 weeks and 4 days who had a prenatal sonogram showing a cystic right abdominal mass and a physical examination demonstrating a palpable mass.- - - - - - - - - - ranking = 3.0980349654632keywords = physical examination, physical (Clic here for more details about this article) |
