40. Desmoplastic Nodular Medulloblastoma-like Tumor Arising from an Ovarian Mature Cystic Teratoma: A Case Report

A secondary somatic malignancy (SSM) occurs due to malignant transformation of a somatic component in a mature cystic teratoma (MCT). The phenomenon is rare, occurring in only 0.2-2% of MCTs, and can mimic immature teratoma. In general, prognosis of mature cystic teratoma with SSM is worse than with MCT alone, and consideration of additional adjuvant therapies specific to the given secondary somatic neoplasm is warranted.
