Pre-pubertal gynaecomastia as the presenting feature of late-onset 21-hydroxylase deficiency.
We describe an 8-year-old boy with pre-pubertal gynaecomastia as the presenting feature of late-onset 21-hydroxylase deficiency, an association not previously reported. Although absolute oestrogen levels were not higher than previously described in 21-hydroxylase deficiency, the gynaecomastia may have arisen through a relative disproportion of the C18 to C19 steroids.
