Seven similar cases with deep ulceration probably due to wet cement are presented. Within 12 hours after making a concrete floor in a kneeling position, curved ulcers developed on both sides of both patellae. The exposure time varied from 2 to 6 h. One patient got wet concrete into her boots and, consequently, ulcers developed on her feet. The high alkalinity of calcium hydroxide in wet cement was the only apparent causative agent in every case.
