A 33-year-old woman presenting with secondary amenorrhea and galactorrhea was found to have a Sertoli cell tumor of the ovary. The neoplasm also had a sex cord tumor with annular tubules (SCTAT) component. Further investigations revealed that in many respects the patient was endocrinologically
Hyperprogesteronemia was found in a dog with alopecia and Sertoli cell tumor. Alopecia began in the lumber areas; the entire coat was dull and dry, and epilated easily. The only laboratory abnormalities were high serum progesterone concentration and incomplete suppression of cortisol after low-dose
The biologic role that estrogen receptor (ER) and progesterone receptor (PR) play in ovarian sex cord-stromal tumors is poorly understood. Furthermore, immunohistochemical data on these hormone receptors in this group of neoplasms are limited and conflicting, with many reports suggesting that
Distinctive ovarian and cervical tumors are associated with Peutz-Jeghers syndrome (PJS). The most common gynecological tumors in this syndrome are adenoma malignum of the uterine cervix and ovarian sex cord tumor, particularly sex cord tumor with annular tubules (SCTAT). Other kinds of ovarian
The main neoplasms in the differential diagnosis for primary ovarian tumors with a tubule-rich pattern are pure Sertoli cell tumor, endometrioid tumors (including borderline tumor, well-differentiated carcinoma, and the sertoliform variant of endometrioid carcinoma), and carcinoid tumor. Because
In 20 sex-cord tumors of the testes, we investigated immunohistochemistry as a possible method for histopathological diagnosis and evaluation of prognosis. We examined the following molecules: inhibin, CD99, cytokeratin, vimentin, MIB-1, estrogen receptors and progesterone receptors. These tumors of
We compared the expression of inhibin A, chromogranin, synaptophysin, S-100 protein, cytokeratins AE1/AE3, 7, and 20, and estrogen and progesterone receptors in testicular sex cord-stromal tumors: 11 Sertoli cell tumors, 3 Sertoli cell adenomas (nodules), 26 benign Leydig cell tumors, 7 malignant
Granulosa cell tumors of the ovary occasionally show admixed Sertoli components, just as tumors that are predominantly Sertoli or Sertoli-Leydig cell tumors can contain minor granulosa elements. Although the immunoprofiles of pure granulosa cell tumors and pure Sertoli cell tumors have been
Objective To analyze the clinical features of 17α-hydroxylase deficiency and explore the appropriate timing and methods of surgical treatment. Methods We retrospectively analyzed the clinical data of patients with complete 17α-hydroxylase deficiency,containing Y chromosome material in their
This case describes the presentation and management of an 8 yr old phenotypically female intersex male dog presented for evaluation of a mass in the right inguinal region. The right inguinal space was surgically explored, and a large irregular mass resembling a fully developed testicle was
Nine ovarian Sertoli-Leydig tumors, showing varying degrees of differentiation, one pure ovarian Sertoli cell tumor, and one poorly differentiated stromal tumor of the testis, were examined for the presence of testosterone, estradiol and progesterone with an indirect immunoperoxidase method on
Cytoplasmic receptors to androgens (AR), estrogens (ER), progesterone (PR) and glucocorticoids (GR) were studied in tumors and normal tissue of the testis in dogs. Peculiarities of distribution of receptors were assessed versus age and tumor histology. Benign Leydig cell tumors failed to reveal AR
The neonatal human Leydig cell undergoes a transient period of activation during the first months of life. The biological significance of this activation is unknown. Furthermore, little is known about the hormonal regulation of this biological process, even though it coincides with an elevation of
We analyzed the clinicopathologic features of 10 cases of vulvovaginal myofibroblastoma to widen its morphological and immunohistochemical spectrum. Most tumors (8/10 cases) were located in the vagina. The patients' age ranged from 44 to 77 years, and tumor size ranged from 0.4 to 3 cm.
Synergistic effects of dysregulation of the WNT/CTNNB1 and phosphatidylinositol 3-kinase (PI3K)/AKT pathways are thought to be important for the development and progression of many forms of cancer, including the granulosa cell tumor of the ovary. Sustained WNT/CTNNB1 signaling in Sertoli cells
