Webbing of the neck, cubitus valgus, congenital lymphangiectatic edema, prominent ears, small mandible, ptosis, dystrophy of the nails, and hypoplastic nipples were among the physical findings he reported. In 1949, Ullrich2 summarized two decades of observations on such patients and noted that there was a 4:1 preponderance of females over males who presented with these clinical features.

The sexual infantilism had not been apparent to Ullrich, whose patients
