[Plurifocal testicular hamartomas and testicular feminization syndrome].
We report the case of a 14-year-old girl with a testicular feminization syndrome. The inguinal cryptorchid testis contained plurifocal hamartomas ranging from 0.5 to 1 cm. They were composed of tubules lined by cylindrical Sertoli cells immunoreactive for alpha-inhibin and p30/32(MIC2). The stroma contained few Leydig cells. Ultrastructural study showed tubules with immature Sertoli cells. The testicular feminization syndrome is caused by mutations of the androgen receptor gene. Patients with male genotype 46, XY have a female morphotype with external sexual organs without ambiguity. They have neither uterus nor ovary but two cryptorchid testis in which sex-cord stromal tumors can develop. Their malignant transformation is rare but requires preventive bilateral orchidectomy.
