Mature cystic teratomas are the most common ovarian germ cell tumour and account for 10-20% of all ovarian neoplasms. Malignant transformation of mature cystic teratomas is rare and has an incidence rate of less than 1%. The most common malignancy are squamous cell carcinomas. Here we present the case of an intestinal adenocarcinoma which is an exceedingly rare malignant entity arising within a mature cystic teratoma. Clinical presentation, imaging and histopathological diagnosis are discussed and previously presented cases in the literature reviewed.
成熟囊性畸胎瘤是最常见的卵巢生殖细胞肿瘤，占所有卵巢肿瘤的10% - 20%。成熟囊性畸胎瘤的恶性转化很少见，发病率低于1%。最常见的恶性肿瘤是鳞状细胞癌。在此，我们报告一例肠腺癌病例，这是一种极其罕见的起源于成熟囊性畸胎瘤的恶性实体肿瘤。本文讨论了其临床表现、影像学及组织病理学诊断，并回顾了文献中之前报道的病例。
