We describe the case of a young female affected by a thymus teratoma coexisting with carcinoid tumor. 1. Introduction Malignant transformation of mature cystic teratoma is a rare complication occurring in approximately 1–3% of patients who have mature cystic teratoma. While any of the constituent tissues of a teratoma has the potential to undergo malignant transformation, squamous cell carcinoma is the most commonly associated malignancy [1]. The majority of mediastinal teratomas are mature teratomas that are histo- logically well defined and benign. Also mature teratomas do have the potential to undergo malignant transformation into a variety of malignancy (adenocarcinoma, rhabdomyosar- coma, leukemia) [1]. Thymic carcinoid is amalignant tumor: metastasis is common and the treatment is complete surgical resection. The prognosis of these tumors, when metastasis occur, are poor but difficult to assess because of little report in literature. Some authors described in kidneys a better prognosis for carcinoid tumor arising within ter
