[Histological structure of the peniform clitoris in congenital adrenogenital syndrome]

Peniform clitoris in 50 girls suffering from congenital adrenogenital syndrome were subtotally removed at the age of 4-6 years and studied by biopsy. A corpus spongiosum more or less developed was found in all cases beneath the corpora cavernosa in the bottom part of corpus clitoridis, epithelial urethral rudiments represented by single or multiple short tubules with transitional epithelium and mucinous glands were found in 46 cases; they were localized in corpus spongiosum or close to it in loose connective tissue. Other urethral rudiments occurring in glans clitoridis were represented by long slight pegs of squamous epithelium extending into corpus spongiosum glandis. Control samples from 20 4-6-year-old girls who had deceased from tumours showed but once heterotopic epithelial urethral rudiments-tubules with transitional epithelium and mucinous glands.
