Leydig cell tumor in a child with spermatocyte maturation and no pseudoprecocious puberty

Leydig cell tumor in a child is uniformly associated with isosexual pseudoprecocity. We report a unique case of an 8-year-old boy diagnosed with Leydig cell tumor who had histologic evidence of discrete spermatocyte maturation and Sertoli cell hyperplasia along the periphery of his tumor but no clinical evidence of pseudoprecocious puberty.
