INTERSTITIAL CELL TUMOR OF THE TESTIS. STUDY OF A 5-YEAR-OLD BOY WITH PSEUDO-PRECOCIOUS PUBERTY*

Abstract
A 9th case of interstitial cell tumor associated with pseudo-precocious puberty in a child is reported, along with a pathologic descr. of the tumor and postoperative follow-up data. Chromatographic studies of the excessive urinary output of 17-ketosteroids showed that these were predominantly 3-a-OH-17-ketosteroids. Removal of this benign tumor resulted in cessation of the abnormal andro-genic activity. This type of tumor in children appears to be limited to the period between 2 and 6 yrs. of age, and the clinical picture seems to be uniform.
