To the Editor.
It was of considerable interest to read about the experience of virilizing adrenal tumors at the Childrens Memorial Hospital, Chicago,1 and the literature review is of particular value. In 1984, we published results from our study during 12 years of 12 infants with virilizing adrenal tumors without cortisol excess. We were able to define very precisely the secretory products of the tumors by using capillary column gas chromatography with mass spectrometry to separate and identify steroids in urine, and the data were rationalized in the context of routine endocrine tests.
