초록
기형종은 주로 전 종격동에서 발생하는 양성 종양으로 대부분 무증상이며 검사에서 우연히 발견된다. 드물게 기형종이 파열하여 여러 합병증을 일으키는 것으로 알려져 있으며 합병증은 급성 증상을 동반한다. 저자들은 급성 증상없이 만성적인 경과를 보인 기형종 파열 1예를 경험하였다. 환자는 왼쪽 폐에 다량의 흉수가 있었는데 배액관 삽입으로 증상이 호전되었으며 지속적으로 흉수의 carcinoembryonic antigen (CEA) 및 carbohydrate antigen 19-9 (CA19-9)이 증가되어서 악성 흉수를 동반하는 종양과 구별이 어려웠다. 본 증례는 이차 감염에 의한 농흉을 치료하기 위해 흉강경으로 확인하기 전까지는 확진이 어려웠고, 매우 높은 흉수 내 악성 종양 표지자 수치를 보인 증례가 국내에는 보고되지 않았으므로 유사 증례의 문헌 고찰과 함께 보고한다.

Abstract
Most mediastinal teratomas are histologically well-differentiated tumors and benign. The majority of patients with a mediastinal teratoma are asymptomatic and their tumors are usually discovered incidentally on chest radiography. On rare occasions this tumor will rupture spontaneously into the adjacent organs. A 72-year-old female patient was admitted for dyspnea and she had a multiloculated pleural effusion in the left lung field. Although repeated pleural biopsy and pleural fluid cytology did not prove the presence of malignancy, we assumed that this was a malignant effusion because it revealed consistently high levels of carcinoembryonic antigen and carbohydrate antigen 19-9, and the chest CT scan did not show typical fat or bone density in the mass. Secondary infection and an uncontrolled septic condition due to pleural empyema finally compelled the patient to undergo a surgical operation. Mature teratoma was the final diagnosis and she has done well without recurrence for 2 months.
