Virilizing Ovarian Leydig Cell Tumor in A Woman with Subclinical Cushing Syndrome

ObjectiveTo report the case of a patient with a virilizing ovarian Leydig cell tumor and subclinical Cushing syndrome attributable to an adrenal adenoma.MethodsDetailed clinical, laboratory, radiologic, and pathologic findings are presented, and the pertinent literature is reviewed.ResultsA 49-year-old woman was referred for evaluation of a left adrenal mass (3.0 by 2.4 cm), which had been diagnosed by computed tomographic scan 4 years previously during a work-up for hirsutism. On examination, she had central obesity, facial hirsutism, and male pattern baldness. Work-up showed elevated total and free testosterone levels of 196 ng/dL (reference range, 20 to 70) and 24 pg/mL (1 to 9), respectively. Other results (and reference ranges) were as follows: dehydroepiandrosterone sulfate, 7.5 μg/dL (10 to 221); corticotropin, 12 pg/mL (5 to 50); morning cortisol, 1.4 μg/dL after a 1-mg overnight dexamethasone suppression test; and urine free cortisol, 48.8 μg/24 h (20 to 100). The testosterone level decreased by 14% after a 2-day low-dose dexamethasone suppression test. Findings on transvaginal ovarian ultrasonography and a computed tomographic scan of the pelvis were normal. A laparoscopic adrenalectomy revealed an adrenal adenoma. On the first day postoperatively, the cortisol level was less than 1.0 μg/dL; however, the testosterone level remained elevated. At 6 months postoperatively, a normal result of a cosyntropin stimulation test indicated recovery of the hypothalamic-pituitaryadrenal axis. Bilateral oophorectomy revealed a 1.3-cm right ovarian Leydig cell tumor. Postoperatively, the testosterone level declined to less than 20 ng/dL.ConclusionTo our knowledge, this is the first case report of a virilizing ovarian Leydig cell tumor in a patient with subclinical Cushing syndrome.

Virilizing Adrenal Ganglioneuroma in a Woman with Subclinical Cushing Syndrome

ObjectiveTo describe a patient with a virilizing adrenal ganglioneuroma and subclinical Cushing syndrome.MethodsDetailed clinical, laboratory, radiologic, and pathologic findings are presented, and the pertinent literature is reviewed.ResultsA 56-year-old postmenopausal woman was referred for evaluation of a 3.6- by 3.0-cm right adrenal mass, which had been diagnosed during a work-up for hirsutism. A bilateral oophorectomy done 2 months before the presentation failed to correct the elevated testosterone levels. On examination, she had severe hirsutism on her face, chest, back, and extremities, as well as male pattern baldness and clitoromegaly. Biochemical evaluation showed elevated total and free serum testosterone levels of 319 ng/dL (reference range, 20 to 70) and 78 pg/mL (reference range, 1 to 9), respectively, values in the adult male range. The serum dehydroepiandrosterone sulfate level was 117 μ/dL (reference range, 10 to 152), and the urine free cortisol was 10.4 μg/24 h (reference range, < 45). A laparoscopic adrenalectomy revealed a 5.0-cm adrenal ganglioneuroma containing nests of adrenocortical cells. On the first day postoperatively, the serum cortisol level was < 1.0 μg/dL. At 1 month after adrenalectomy, the total and free testosterone levels had declined to 16 ng/dL and 3.1 pg/mL, respectively. At 2 months postoperatively, normal results of a cosyntropin stimulation test (basal and peak cortisol levels of 13.6 and 20.0 μg/dL, respectively) indicated recovery of the hypothalamic-pituitary-adrenal axis.ConclusionTo our knowledge, this is the first case report of a virilizing adrenal ganglioneuroma with this unique pathologic finding and concomitant subclinical Cushing syndrome.

Cushing Syndrome in a Young Woman Due to Primary Pigmented Nodular Adrenal Disease

ObjectiveTo report a case of Cushing syndrome due to apparently sporadic primary pigmented nodular adrenal disease in a young woman.MethodsWe describe the clinical, biochemical, radiologic, and histologic findings of Cushing syndrome due to the rare condition of primary pigmented nodular adrenal disease.ResultsA 30-year-old woman presented with a 2-year history of worsening itch without rash over her shoulders and arms and weight gain, particularly around the abdomen and face. Careful questioning did not elicit any history of exogenous glucocorticoid use (systemic or topical), including hydrocortisone. On examination, the patient had a slightly rounded and plethoric face, a small buffalo hump, central adiposity, and thin skin with a few small striae on her inner thighs. No features of the Carney complex were observed. Investigations showed hypercor- tisolism with suppressed corticotropin and normal adrenal imaging despite documentation of enlarged adrenal glands at removal. High-dose dexamethasone administration was followed by a decrease in urinary free cortisol excretion rather than a paradoxical rise as previously reported in primary pigmented nodular adrenal disease. No mutations were detected in the PRKAR1A gene.ConclusionsPrimary pigmented nodular adrenal disease should be suspected in patients with corticotropinindependent Cushing syndrome who have normal adrenal imaging. The role of genetic testing in apparently sporadic cases is not established, but cumulative experience may be helpful in defining the frequency of PRKAR1A mutations.

Paracoccidioidomycosis in a Woman with Idiopathic Hirsutism

Paracoccidioidomycosis, especially the chronic pulmonary form of the disease, is not commonly described in females. Data from in vitro and vivo studies support the hypothesis that estrogens might influence the pathogenesis of paracoccidioidomycosis in humans by inhibition of transition of conidia or mycelia to yeast form of Paracoccidioides brasiliensis. The authors describe a chronic progressive pulmonary form of paracoccidioidomycosis in a woman with idiopathic hirsutism. In addition to estrogens, the present report suggests that other hormonal factors might play an important role in the pathogenesis of paracoccidioidomycosis, including the increased production of 5alpha-dehydrotestosterone frequently described in individuals with idiopathic hirsutism.     

Nephrotic Syndrome with Heart Disease: A Reappraisal

The evidence that heart failure alone may cause a nephrotic syndrome is inconclusive. Mercurial diuretics, which have also been implicated as a cause of the nephrotic syndrome, had been given in 23 of the 24 well-documented cases.Two cases of heart disease and nephrotic syndrome are described. Glomerular lesions were minimal on light microscopy, but thickening of the glomerular tuft basement membrane and partial fusion of the epithelial cell foot processes were apparent on elecronmicroscopy. The response to prednisone was such as to justify a trial of corticosteroid therapy in such cases despite the presence of cardiac disease.
