[Burns related to the use of cement. Apropos of 4 cases]

Four patients suffering from cement burns are reported. Lesions consist of sharp-edged necrotic ulcerations, leaving hypertrophic scars after a normal course of six weeks to two months. Patch-tests are constantly negative in all patients. Quick-setting cement, and in particular ready mixed cement, is usually responsible for such lesions. Additional factors include prolonged contact with cement, pressure and/or occlusion. Cement burns are therefore considered to be alkaline burns. An increased use of premixed cement by non-occupational users play an important role in the actual frequency of such lesions. Mandatory preventive measures are needed; correct use of cement, adequate protective garments, cleaning and drying of the skin after work, etc.
