Background. Development of neuroepithelial tumors from mature cystic teratoma is very rare. We present a case of oligodendroglioma developing inside mature cystic teratoma.
Case. Eighteen-years-old female, right adnexal mass with solid and cystic areas was detected. Sections showed all three germ layers. Also, a tumoral lesion was observed in a glial fibrillary matrix. Tumor was composed of monotonous, uniform cells which have oval-round nucleus, perinuclear halo, and indistinct cytoplasm. GFAP, EGFR, P53 were positive. Conclusions. We diagnosed oligodendroglioma arising from mature cystic teratoma. There was no recurrence at the end of 13 months followup. The number of cases which have been reported in the literature is only a few.
<p>Invasion of the wall of the digestive system by ovarian cancer cells isn’t so rare. On the other hand, fistula formation between the tumor and digestive system is an uncommon status. We described a patient with ovarian serous carcinoma that was fistulized into jejenum and formed a region composed of stool and tumor surrounded and limited by small intestines recognized during surgery. This diagnosis should be kept in mind while preparing a patient for ovarian cancer surgery if the patient has acute abdomen or abdominal pain incompatible with the extent of the tumor.</p>
Lenfanjiomalar, lenfatik sistemdeki blokaj ile lenf damarlarının proliferasyonu sonucu ortaya çıkan benign kistik oluşumlardır. Sıklıkla boyun ve aksillada lokalize olur ve pediatrik yaş grubunda karşılaşılır. Mezenterik kist ayırıcı tanısında yer alan abdominal lenfanjiomalar ise oldukça seyrek görülen kistik lezyonlardır ve sıklıkla ince bağırsak mezenterinde yerleşir. Kistin büyüklüğü ve lokalizasyonuna göre farklı semptomlar ile presente olur. Literatürde tüm yaş gruplarında 200’den daha az sayıda abdominal lenfanjioma olgusu bildirilmiştir. Bu yazımızda, rutin jinekolojik muayene sırasında tesadüfi olarak saptanmış olan ve preoparatif değerlendirme sonrası mezenterik kistik lezyon ön tanısıyla opere edilen abdominal mezenterik kistik lenfanjioma tanılı bir olguyu sunmayı amaçladık.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
