An asthmatic child is presented who developed a cushingoid appearance with evidence of adrenal suppression and growth impairment while on low dose inhaled topical steroids. When the inhaled steroids were replaced by inhaled sodium cromoglycate his adrenal function recovered while his appearance and growth returned to normal. This report indicates that there are some children who are at risk of developing side-effects on doses of inhaled topical steroids normally considered to be entirely safe.
