Squamous cell carcinoma in a pre-existing adult mature Sacro-Coccygeal teratoma: A rare case with review of literature

We report a case of sacrococcygeal teratoma with squamous cell carcinomatous transformation in a 40-year-old lady. This is an infrequent location for teratoma in adults and malignant transformation has rarely been described. The uniqueness of the present case was the presence of congenital sacrococcygeal teratoma presenting in adulthood with malignant transformation.
