[Malignant transformation of a dermoïd cyst of the scalp. A case report].Tunis Med. 2004 Oct; 82(10):972-5.TM
Dermoïd cysts are benign tumours, resulting of an embryologic defect. They usually have good prognosis, only a single case of malignant transformation of a sublingual dermoid cyst has been brought back in literature. We report a case of carcinomatous transformation of a dermoïd cyst of the scalp, in a 54 years old man.
