Immunohistochemical study of inhibin A and B expression in placentas from normal and pathological gestations.

Objective: The aim of the study was to examine, by an immunohistochemical method, the distribution of Inhibin-A and -B, in placentas from normal and pathological gestations.

Materials And Methods: Sixty-two specimens of placental tissue were examined: i) ten cases from early gestations, ii) 28 cases from mature placentas, iii) six cases associated with intrauterine growth restriction, iv) four cases associated with diabetes mellitus and v) 14 placentas from gestations with fetal chromosome abnormalities. The expression of Inhibin A and B was studied by automatic Ventana method.

Autopsy findings in fetuses with cystic hygroma: a literature review and our center's experience.

Purpose Of Investigation: To report our experience of autopsied cases of fetal cystic hygroma (CH) and discuss the role of fetal autopsy in genetic counseling.

Methods: A review of autopsy reports at our institution revealed 18 cases of fetal CH over a 10-year period (from 2000 to 2010). The clinical data, results of cytogenetic analysis and prenatal ultrasound findings were also retrieved and compared to the autopsy findings.

Peritoneal mesotheliomas mimicking adnexal tumors. Clinicopathological characteristics of four cases and a short literature review.

Three cases of peritoneal benign cystic mesotheliomas in women 32-34 years of age and one case of peritoneal malignant mesothelioma in a 47-year-old woman are reported. All cases presented with abdominal discomfort and/or pain and the physical and radiological diagnostic methods showed adnexal tumors. The cystic mesotheliomas developed in the cul-de-sac and the right pelvic sidewall, presented as multiple small cysts or large multilocular cystic mass.

Monodermal teratomas (struma ovarii). Clinicopathological characteristics of 11 cases and literature review.

During the last 15 years in the Pathology Laboratory of Aretaieion University Hospital, 256 cases of teratomas were examined and 11 cases (4.3%) presented characteristics of struma ovarii. Eight patients aged 19-34 years and four 41-74 years (median 41 years).

Clinicopathological features and immunoprofile of 30 cases of Brenner ovarian tumors.

Aim: The aim of this study was to investigate the clinicopathological and immunopathological features of Brenner ovarian tumors.

Materials And Methods: Thirty cases of Brenner ovarian tumors were examined in our laboratory among 1,680 cases of ovarian tumors, representing 1.5% of all tumors examined.
