[Hemihypertrophy and functioning adrenal tumor (author's transl)]

The case of a secreting adrenal tumor in a seven month old hemihypertrophic girl is described. Some features of hemihypertrophy and its relationships with the E.M.G. Syndrome and abdominal tumors are commented upon. The reported case is a typical association of malformation with tumor and recalls the close relationship between teratogenesis and oncogenesis.
