OBJECTIVE
Immunohistochemical staining is reported to be useful in distinguishing ovarian Sertoli-stromal cell tumors from carcinosarcomas. To assess Sertoli cell differentiation in a rare malignant biphasic testicular tumor, we compared the immunophenotypic profile of the tumor with that of Sertoli
Primary testicular tumors are the most common causes of cancer in male dogs. Overall, the majority of canine patients should be cured by testicular surgery. However, tumor markers are not well-known in veterinary medicine. We sought to determine using immunohistochemistry whether the combined human
Four cases of large cell calcifying Sertoli cell tumor, 3 benign and 1 malignant, with no clinical signs of Carney complex or Peutz-Jeghers syndrome are reported with results of histologic, immunohistochemical, ultrastructural, and comparative genomic hybridization studies. Analysis of PRKAR1A gene
Sertoli cell tumor of the testis (not otherwise specified) in a 43-year-old man is reported. Macroscopically, the testicular mass measured 3.0 x 2.3 x 1.5 cm and was well circumscribed. The cut surface was white to tan-gray in color. Neoplastic cells with eosinophilic cytoplasm proliferated with
The distinction of Sertoli cell tumors from seminoma is critical to ensure proper treatment. Although usually straightforward, we highlight herein 13 malignant Sertoli cell tumors of the testis with light microscopic features that mimicked seminoma. All of the cases were received in consultation, 10
Sertoli cell tumor is a potential histologic mimic of other tumors, such as seminoma due to similar histology and overlapping clinical presentation. Sclerosing Sertoli cell tumor is a rare sex cord stromal tumor variant, with 16 cases reported in the English literature. We present an unusual case of
A panel of seven alkaline phosphatase labeled lectins was used to probe nitrocellulose electroblots of SDS-PAGE separated proteins from a primary culture of normal ovarian granulosa cells and an ENU-induced Sertoli cell tumor cell line (SCTL-I). Several additional lectin binding proteins were
Dysregulated WNT/β-catenin signaling in murine testes results in a phenotype with complete germ cell loss that resembles human Sertoli cell-only syndrome. In other systems, including the ovary, dysregulated WNT/β-catenin induces tumorigenesis but no tumors are observed in the mutant testes without
This study aimed to explore the clinicopathological characteristics and differential diagnosis of primary neuroendocrine tumor (G1) of the testis. In this paper, we analyze the clinical, histomorphological and immunohistochemical findings, treatment and prognosis of a patient with primary
Testicular Sertoli cell tumors are extremely rare. Generally, they are benign neoplasms, which belong to a group called sex cord-stromal tumors. In this article, we present a case report of a Sertoli cell tumor, which was accidentally discovered during a urological consultation of a 42-year-old
Gonadal germ cell tumors continue to be the cause of diverse, diagnostically challenging issues for the pathologist, and their correct resolution often has major important therapeutic and prognostic implications. They are academically interesting because of the biological diversity exhibited in the
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
