1.To review the imaging findings of various malignant tumors arising from benign lesions and compare with imaging characteristics of underlying benign disease. 2.To discuss the differential diagnosis and pitfalls.

1. Introduction of malignant transformation of benign lesions. 2. Review the imaging findings of malignant tumors arising from benign lesions including but not limited to: Adenocarcinoma arising from pulmonary scar Hepatocellular carcinoma arising from Hepatic adenoma Collision tumor of the adrenal gland Leiomyosarcoma arising from uterine fibroid Clear cell carcinoma arising from abdominal wall scar endometriosis Endometroid carcinoma arising from adenomyosis Squamous cell carcinoma arising from benign teratoma Neurofibrosarcoma arising from neurofibroma Angiosarcoma arising from hemangioma Summery: Malignant transformation of benign lesions is a rare complication that may create a diagnostic challenge to the radiologists. This exhibit aims to display the imaging findings and enhance the radiologic evaluation of various benign lesions with malignant transformation.
