The objective of this study was to evaluate the reliability of an intraoperative frozen section during the endometrial carcinoma staging surgery procedure. The paraffin section reports of 291 cases with endometrial carcinoma were compared with intraoperative frozen section reports, which were diagnosed in the Pathology Department of Cukurova University, Medical Faculty between June 2006 and December 2012. The reports were reviewed for diagnostic accuracy of the frozen section in terms of histological subtype, grade, and myometrial invasion. Concordance values between frozen and paraffin section reports were 86, 84.3, and 91.6% for histological subtype, grade, and myometrial invasion, respectively. When collectively evaluated, two (0.7%) of 291 patients were inappropriately operated on due to frozen section reports. Intraoperative frozen section is a reliable guide for surgeons to evaluate the risk group of patients with endometrial cancer and prevent an unnecessary staging surgery operation.

Objective: Frozen section is an accurate diagnostic tool with some unavoidable pitfalls in gynecologic tumors. We aimed to evaluate the diagnostic value of frozen section, and to detect the factors causing erroneous diagnosis in ovarian tumors. Material and Method:Frozen section and paraffin section reports of 282 patients with ovarian neoplasms diagnosed between July 2006 and January 2013 in our institute were re-analyzed. Results were grouped into benign, borderline (for epithelial tumors) and malignant categories and compared between frozen section and paraffin section diagnosis, statistically. Results:Overall diagnostic accuracy of frozen section was 96.5%. Sensitivity of frozen section for benign, borderline and malignant tumors were 97.5%, 95.8%, and 95.6% and the related specificities were 97.5%, 97.6%, and 100%, respectively. We found the lowest positive predictive value in borderline group (79.3%), all of them with mucinous type epithelium. Second frequent discordant tumor type was immature teratoma. Conclusion:Apart from the limitations of frozen section, pathologists should be aware of the pitfalls of technique and tumor types and tend to sample from the solid areas particularly in mucinous tumors and teratomas to avoid inappropriate surgery. Bulgular:Frozen incelemenin genel tanısal doğruluk oranı %96,5 idi. Benign, borderline ve malign tümörler için frozen incelemenin duyarlığı sırasıyla %97,5, %95,8 ve %95,6 idi. Özgüllük ise aynı sırayla, %97,5, %97,6 ve %100 idi. En düşük pozitif prediktif değer borderline grubunda saptandı (%79,3) ve hataya neden olan tüm olgular müsinöz tip epitelyal tümörler idi. Tanı uyumsuzluğu bulunan ikinci tümör grubu ise immatür teratom idi. Sonuç:Frozen incelemenin kısıtlılıkları yanısıra, patoloğun frozen incelemenin teknik veya tümör tipi ile ilgili tuzaklarını bilmesi, özel-likle müsinöz tümörler ve teratom olgularında solid görünen alanlardan örneklenmesi yetersiz veya gereksiz operasyon yapılmasını önlemek adına yararlı olacaktır.

Objective: We aimed to document the reasons of perinatal deaths in a large autopsy series performed in our institute, which is a reference center in the Çukurova region of Turkey. Material and Method:The study included 2150 autopsies performed between January 2000 and December 2012at our institute. Diagnoses were categorized according to the detected pathologies; congenital malformations were detailed based on systems. Results:A pathology was detected in 1619 of 2150 (73.3%) autopsies. Congenital malformations were the most common diagnosis with 68.2%. Neural tube defects and central nervous system malformations were the most frequent system malformation in 28.8% of cases, followed by the urogenital system (11.4%) and musculoskeletal system (8.3%), respectively. Malformation syndromes including multisystem anomalies were defined in 109 cases (9.3%). Conclusion:Congenital malformations are the most common reason for perinatal deaths, with autopsy having an additive role to prenatal and genetic evaluations and providing foresight for planning a subsequent pregnancy. Sonuç: Fetal otopsi prosedürü, son yıllarda sayısal düşüş göstermekle birlikte, özellikle gebelik beklentisi olan kişiler için, prenatal tarama yöntemlerine tanısal katkısı olmakta ve malformasyonun yineleme olasılığı hakkında öngörü sağlamaktadır.
