Pubic hair, normally a sign of the onset of puberty, can occur - as can menstruation at a
surprisingly early age.
H. Jolly mentions a boy of only eighteen months who had both an enlarged penis and pubic
hair. Often such
conditions are associated with a number of other abnormalities. In the cited case the boy
"presented with a
right-sided abdominal mass." Autopsy showed the mass to be a primary hepatoblastoma.
