title: Malignant change in a mediastinal dermoid cyst.
abstract: Mature benign cystic teratomas, or dermoid cysts, usually arise in the ovary. They can, however, occur at other sites, including the mediastinum. Malignant change within dermoid cysts is a rare but recognized complication, occurring in 1%-2% of cases. A case of malignant change within a mediastinal dermoid cyst occurring 19 years after initial presentation is described.
