RESUMEN
Mature cystic teratoma of the ovary is the most commom ovarian germ cell tumor and almost benign. Malignant transformation occurs in less than 2% of benign mature teratoma. Squamous cell carcinoma derived from ectoderm is the most frequent malignancy. Prognosis of squamous cell carcinoma in ovarian mature teratoma is generally poor but there is no consensus on optimal thrapy. We report one case of squamous cell carcinoma arising from mature cystic teratoma with a brief review of the literature.

An adenosquamous carcinoma of the penis is an exceedingly rare, highly malignant tumor, with histological features of a squamous cell carcinoma and an adenocarcinoma, which originates in the penile surface epithelium, and possibly in embryologically misplaced mucus glands of the perimeatal region of the glans mucosa. We report a case of an adenosquamous carcinoma of the penis in a 73-year-old man who had been suffering from a painful ulcerative mass on his penis for 2 years.
