Dermoid cyst: usually mature teratoma which resembles skin; some use these terms interchangeably Gliomatosis peritonei: peritoneal implants exclusively composed of mature glial tissue; benign if all tissue is mature and other teratomatous elements are absent The most common of these tumors, the mature cystic teratoma (also known as dermoid cyst), typically contains mature tissues of ectodermal (skin, brain), mesodermal (muscle, fat), and endodermal (mucinous or ciliated epithelium) origin. Figure 10d. In contrast, immature teratomas are not known to arise from mature cystic teratomas; thus, the term malignant transformation applies only to malignancy arising de novo in a preexisting benign mature cystic teratoma. 6, 15 June 2012 | Indian Journal of Surgery, Vol. Mucinous carcinoid tumors have higher signal intensity on T2-weighted MR images than do most solid tumors because they contain high-signal-intensity mucin (,,,,,Fig 11).
