TURNER,1 in 1938, presented a syndrome of infantilism, congenital webbed neck, and cubitus valgus in seven short girls ages 15 to 23 years. Since then, many similar cases have appeared in the literature,* and the syndrome has been further elaborated. The essential features were categorized in 1953 by Jackson5 under three headings:
(1) gonadal agenesis, with resultant primary amenorrhea, poorly developed secondary sex characteristics, increased gonadotropin, and diminished 17-ketosteroid excretion
(2) skeletal defects, including short (not dwarfed) stature, a constant finding, and a group of anomalies commonly, though not invariably, found, as webbed neck, short neck, cubitus valgus, shield-shaped chest, wide arm span, fused cervical vertebrae, and shortened phalanges
(3) associated nonskeletal anomalies, including mental retardation, ocular and renal defects, and vascular anomalies, such as coarctation of the aorta and hypertension without coarctation.
The first case of the Turner syndrome in the male was reported by Flavell,6
