General description

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

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.

Through a brief introduction of inhibin history, characteristics of the antibody against inhibin, and normal tissue distribution of alpha-inhibin expression, this comprehensive review focuses on a practical approach to using alpha-inhibin in the differential diagnosis of ovarian sex cord-stromal tumors
