Persistent solid facial edema is considered a complication of acne vulgaris and has never been reported in the French literature. The authors report the cases of 2 patients, a 15-year old girl and a 20-year old man, who suffered from the condition for 1 and 2 years respectively. Clinical features and course are described. Treatment with isotretinoin in doses of 1 mg/kg/day administered during 6 and 8 months resulted in an 80 p. 100 and 50 p. 100 reduction of the edema respectively.
