1/23. Diffuse stromal Leydig cell hyperplasia: a unique cause of postmenopausal hyperandrogenism and virilization.A 60-year-old woman presented with diffuse scalp alopecia, hirsutism, and clitorimegaly, and the mean serum testosterone levels were greater than 200 ng/dL. Findings on computed tomography of both adrenal glands were normal. After bilateral oophorectomy, a unique histological picture consisting of diffuse stromal Leydig cell hyperplasia was found. Reinke crystals were present, but neither hilus cell hyperplasia nor stromal hyperthecosis was noted. Sequencing of the 11 exons of the gene for the luteinizing hormone receptor revealed no abnormality. Relevant data suggest that treatment of the postmenopausal woman with hyperandrogenism and virilization is bilateral laparoscopic oophorectomy if she has no pronounced ovarian enlargement or adrenal tumor on imaging. In this setting, an intensive endocrine evaluation or a search for metastatic disease seems to be unnecessary.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/23. Selective testosterone secreting adrenocortical carcinoma in an infant.adrenocortical carcinoma in children is a rare tumor of adrenal gland. An infant presented with signs of virilization due to selective testosterone hypersecretion. Diagnosis was established with the help of the computerized tomographic scan and histopathological examination. Following adrenalectomy patient made uneventful recovery and six months later does not have any clinical or laboratory evidence of recurrence or metastasis.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
3/23. Extraovarian steroid cell tumor 'not otherwise specified' as a rare cause of virilization in twelve-year-old girl.BACKGROUND: We present a 12-year-old girl with a 5-year history of progressive virilization. RESULTS: Regarding elevated plasma levels of 17-hydroxyprogesterone (17-OHP) and androgens, normal ultrasound and CT scan of ovaries and adrenal glands, the nonclassic form of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency was presumed the cause of virilization. As the glucocorticoid therapy did not normalize high levels of 17-OHP and androgens, and the dna analysis did not demonstrate a mutation causing CAH, a laparotomy was performed. Near the right ovary a tumor was found and extirpated. Pathohistological studies determined it to be a rare steroid cell tumor, 'not otherwise specified'. Within the next months the signs of virilization resolved and menarche occurred. CONCLUSIONS: Steroid cell tumor should be considered in differential diagnosis of virilization in childhood. Regarding the age of our patient and pathohistological findings of the tumor, her prognosis is favorable.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
4/23. Androgen-secreting adrenal adenomas.BACKGROUND: The androgen source in women with hirsutism and signs of virilism may be the ovary or adrenal gland. CASES: Three patients with androgen excess are reported. Two had hyperandrogenemia and cushing syndrome with an adrenal mass greater than 5.5 cm; the third had a small adrenal adenoma secreting only testosterone and responsive to human chorionic gonadotropin. In all cases, the pathologic report from surgery and the long-term resolution of symptoms confirmed the benign nature of the tumors. CONCLUSION: Basal and dynamic hormonal tests cannot precisely differentiate ovarian from adrenal tumors. Adrenal adenomas must be considered as a cause of hyperandrogenic syndrome.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
5/23. An unusual case of multiple giant myelolipomas: clinical and pathogenetic implications.Myelolipomas are benign tumors composed of both mature adipose and myeloid tissues. They typically present as an incidental mass in one of the adrenal glands proper. However, they can occur in ectopic adrenal tissue or, rarely, without associated adrenal tissue in various locations and can grow to weights of several kilograms. These tumors have been linked to endocrinopathies, such as Cushing disease and congenital adrenal hyperplasia, which involve overproduction of adrenocorticotropic hormone. We report a case of three giant adrenal myelolipomas arising in a persistently virilized female with congenital adrenal hyperplasia, supporting a role for hormonal stimuli in myelolipoma formation.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
6/23. Mucinous cystadenoma of the ovary with functioning stroma and virilization in pregnancy: a case report and review of the literature.Virilization caused by ovarian tumors with functioning stroma during pregnancy is extremely rare and has been reported in many ovarian tumors. In mucinous cystadenomas with maternal virilization during pregnancy the stromal cells responsible for the hormone secretion resemble lutein or leydig cells and have been referred to as luteinized stromal cells. We present a case of a 30-year-old, gravida 2, para 1, woman who presented at approximately the 38th week of pregnancy with features of virilization. At the same time, a cesarean section was performed because of fetal distress and a male weighing 3,030 g without any gross abnormalities was delivered. A large tumor of the right ovary was detected and a right salpingo-oophorectomy was performed. Histopathologically, the tumor proved to be a benign mucinous cystadenoma. Masses typically resembling lutein stromal cells or leydig cells of the testes or ovarian hilus were found in the wall of the cyst below the mucinous epithelium. No crystalloids of Reinke were identified. The stromal component of the tumor was characterized as functioning stroma with luteinized stromal cells. The glandular mucinous epithelium showed focal positivity for human chorionic gonadotrophin. The cytoplasm of the luteinized stromal cells reacted strongly and diffusely with antiserum for vimentin. Also, the cytoplasm of the luteinized stromal cells showed focal intense positivity for synaptophysin, and focal mild positivity for human chorionic gonadotrophin. Staining results for oestrogen and progesterone receptors were negative. In conclusion, we present an unusual case of clinical virilization during pregnancy associated with an ovarian mucinous cystadenoma with functioning stroma. The virilizing manifestations disappeared after removal of the ovarian neoplasm, supporting the perception that the functioning ovarian stroma was responsible for the androgen production.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
7/23. adrenocortical adenoma associated with inadequately treated congenital adrenal hyperplasia.We report a 6 year-old boy with the simple virilizing form of 21-hydroxylase deficiency in whom an adrenal adenoma developed following 5 years of steroid treatment. Extremely high levels of basal serum 17alpha-hydroxyprogesterone as well as an exaggerated response of 17alpha-hydroxyprogesterone to adrenocorticotropic hormone confirmed congenital adrenal hyperplasia at 7 years of age. Initially elevated serum steroid levels were restrained by high dose hydrocortisone therapy, but he chronically tended to take inadequate doses of glucocorticoid. At 12 years of age an adenoma was found in the cortex of the hyperplastic right adrenal gland. The importance of early diagnosis and compliance with medication in the simple virilizing form of 21-hydroxylase deficiency is stressed.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
8/23. Disappearance of a virilizing adrenal tumor following therapy with cyproterone acetate.A 57-year-old woman presented with an apparently obvious diagnosis of iatrogenic virilization. At the age of 51, she began a 4-year treatment with prednisone or cyclosporine, which are known to promote hair growth, for Behcet disease. At the age of 56, osteoporosis was overtreated with the anabolic steroid nandrolone. Insignificant inhibition by dexamethasone of the extremely high serum concentrations of testosterone and less high concentrations of weak androgens prompted us to search for a virilizing tumor. Computed tomography showed a 2.3 x 1.5 cm nodule in the right adrenal gland. As the patient refused surgery, virilization was treated with the antiandrogen cyproterone acetate (CPA), but for only 4 months because clinical and hormone abnormalities reversed and the tumor was no longer visible. The patient remains symptom-free. This first report of a curative effect of CPA on a purely virilizing adrenal tumor opens new avenues in the management of such tumors.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
9/23. Complex genital malformation in a female with congenital adrenal hyperplasia: evaluation with magnetic resonance imaging.This is a case of complex genital malformation in a young patient with congenital adrenal hyperplasia. The magnetic resonance imaging (MRI) findings included ostium of the vagina into the urethra (common urogenital opening), prostate-like tissue surrounding the urethra, and hyperplasia of the left adrenal gland. The report provides information on the clinical findings, the MRI examination, including the applied sequences and the MR findings, and gives an overview of the disease pattern and its frequency of occurrence.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
10/23. Virilizing Leydig cell adenoma of adrenal gland.We describe the third report testosterone-producing, virilizing, adrenal Leydig cell adenoma, which was identified in a oophorectomized postmenopausal female patient. light- and electron-microscopy demonstrated typical Leydig cell differentiation, including numerous intracytoplasmic and intranuclear Reinke crystals and rice-like bodies (elementary tubular inclusions). testosterone production by the adenoma was demonstrated by the immunoperoxidase technique. We propose that adrenal Leydig cell adenomas arise as a result of ovarian gonadal stromal metaplasia associated with elevated follicle-stimulating hormone and luteinizing hormone in the postmenopausal female patient. Adrenal Leydig cell lesions must be considered in the virilized woman with elevated testosterone levels and normal levels of the adrenal androgens and their 17-ketosteroid metabolites.- - - - - - - - - - ranking = 4keywords = gland (Clic here for more details about this article) |
