Testicular cancer in androgen insensitivity syndrome in a Mexican population.

Male pseudohermaphroditism and androgen insensitivity syndrome cases have an increased risk of developing testicular cancer due to many factors such as mutations, hormonal disturbances involving gonadotropins and cryptorchidism. We describe the clinical features, diagnosis and treatment of two cases with partial androgen insensitivity syndrome and testicular cancer development, which were handled at the National Cancer Institute of Mexico.
