Description générale

Calretinin is a 29 kDa calcium-binding protein thought to play a role in the cell cycle. Anti-calretinin has been shown to be useful in differentiating mesothelioma from adenocarcinomas from the lung and other sources. The sensitivity of anti-calretinin in distinguishing reactive mesothelial cells from adenocarcinoma cells is 100%, and the specificity is up to 80%. Light, focal, cytoplasmic staining of adenocarcinoma cells may be seen in 10 to 30% of cases. Anti-calretinin has also demonstrated utility in differentiating adrenal cortical neoplasms (+) from pheochromocytomas (-). Calretinin has also been useful in diagnosing granulosa cell tumor of the ovary amongst its mimics. Other ovarian tumors that stain with calretinin are Sertoli-Leydig cell tumor, Sertoli cell tumor, Leydig cell tumor, and sex cord tumor with annular tubules, as well as steroid cell tumor.9

Morphologic distinction between adrenal cortical and medullary tumors can be difficult. Previous studies have shown inhibin, melan-A, and BCL-2 to be useful markers for adrenal cortical tumors. We have recently observed a high level of calretinin expression in normal adrenal

Immunohistochemistry using monoclonal antibodies against human inhibin, a peptide hormone produced by ovarian granulosa cells to inhibit follicle-stimulating hormone (FSH), has been recently applied to diagnostic anatomic pathology. This investigation hypothesizes that inhibin immunohistochemistry will aid in the crucial clinical

Inhibins are peptide hormones that participate in the regulation of the pituitary-gonadal feedback system and are selectively expressed by cells of sex cord-stromal derivation. To determine the efficacy of this marker for distinguishing granulosa cell tumors, 134 primary and metastatic

Inhibin is a glycoprotein hormone produced by normal ovarian granulosa cells and testicular sertoli cells. In the ovary, it inhibits the secretion of follicle-stimulating hormone. Patients with granulosa cell tumors (GCT) have elevated serum levels of inhibin and this finding

Most adrenocortical neoplasms and pheochromocytomas can be diagnosed by a combination of clinical findings and morphologic features. Occasionally, however, this histologic differential diagnosis requires ancillary tests, such as immunohistochemistry. Both tumors are generally negative for epithelial markers but express synaptophysin.
