Background and Objective: Histopathological evaluation of granulosa cell tumors (GCT) of the ovary may be confused morphologically with a wide variety of the tumors. Immunohistochemical staining for inhibin and calretinin can be used for better diagnosis. Although it has been suggested that inhibin can be a sensitive marker for GCT, it maybe had negative results in some cases. In addition, caltrinin has been proposed as a marker for GCT. The aim of this study was to investigate the immunohistochemical methods (IHC) including a comparison of calretinin and inhibin markers in the diagnosis of these tumors. Patients and Methods: This prospective study carried out from 2000 to 2009 at Ghaem and Omid hospitals, Mashad University of Medical Sciences, Iran. A total of 23 ovarian GCT specimens were immunostained with commercially available antibodies to find out calretinin and inhibin immunoreactivity. Data were analyzed by descriptive statistical method. A P value of =Results: For diagnosing GCT, the sensitivity of calretinin was 100% and that of the inhibin was almost 73.9%. The extent and severity of staining was more extensive for calretinin compared to inhibin PConclusion: Calretinin is a more sensitive biomarker for GCT than inhibin.

Background and Objectives: Presence of steroid hormone receptors (estrogen and progesterone) in the tumor tissues of various organs correlates with response to therapy and prognosis. Since their role in ovarian cancer is still controversial, in this study we investigated the expression and prognostic value of the estrogen receptor (ER) and progesterone receptors (PR) in ovarian papillary serous carcinoma (PSC). Material and Methods: In this retrospective study we determined the expression of tissue receptors including tissue samples from 36 patients with stage III ovarian PSC by Immunohistochemistry method. Then ER and PR expression correlated with clinicopathological parameters and possible prognostic impact on ovarian PSC were investigated. Results: The correlation between age and survey of patients with ovarian PSC and expression of steroid receptor was not significant. Although correlation between severity of expression of PR and mortality rate was not meaningful, the relationship between severity of ER expression and mortality rate was significant (P=0.02) Conclusion: The determination of steroid receptor status may offer additional prognostic information in ovarian carcinoma (PSC).
