Abstract

Malignant degeneration of mature cystic teratoma has been reported in 1~3% of cases, usually between the age of 30 and 70 years with a peak incidence of 40~60 years. The most common malignancy developing in such tumors is squamous cell carcinoma arising in a mature cystic teratoma. Hirakawa reported two patients with benign teratomas diagnosed 25 and 32 years prior to surgery for malignancy and Dorothea reported a patient who was diagnosed as benign teratoma 50 years prior to operate for carcinoma. But there has been no report of squamous cell carcinoma arising in the mature cystic teratoma with direct invasion to gastrointestinal tract. We report a case of squamous cell carcinoma with direct invasion to transverse colon and jejunum in 62-year-old female who was diagnosed as mature cystic teratoma 20 years ago.
