Abstract

A 20-year-old woman was admitted to our clinic with chest pain. On plain chest X-ray it was seen that there was a mass in right anterior mediastinum, which was hypodense, cystic, regularly bordered and septated and which had a thick wall. Explorative thoracotomy was performed in this patient in whom the diagnosis Could not be established via biochemical, serological, microbiological tests and fiberoptic bronchoscopy. During the operation, a cystic lesion of 8x10 cm was found in the right anterior mediastinum and it was totally resected. Pathological evaluation revealed mature cyctic teratoma. The patient who had no complications during the follow-up period was discharged from hospital. Mediastinal mature teratomas which contain pancreatic tissue is a rarely seen mediastinal pathology.
