Two male cleaning workers aged 62 ( @entity1 1) and 28-( @entity1 2) presented with red, swollen, aching hands and fingers. At the first interview, the fingers of the right hand of both @entity1 were swollen from the proximal interphalangeal joint to the tip of the finger. The fingers were red and intensely @entity158 . The bleach that both @entity1 used contained 9.5% @entity14039 , and therefore we diagnosed their symptoms as those of burns caused by this agent. We subcutaneously injected 8.5% @entity10041 into the affected fingers and dressed them with gauze soaked in cooled 0.025% @entity21711 . The @entity1 did not use gloves at work, neither of them knew that the cleaning fluid contained dilute @entity14039 , and they were unaware of the danger of this agent. They had not received proper education about the care and handling of poisons and deleterious substances such as @entity14039 . The doctors who had examined the @entity1 in the emergency ward overlooked the possibility of @entity14039 burns, although they suspected chemical burns and confirmed the trade name of the cleaning agent. In addition, although the @entity1 presented with intense @entity158 , no white areas of coagulation and blistering, or surrounding erythemas, which are characteristic symptoms of such burns, were evident. The component of the cleaning agent was described on the container label in very small print. Had the words "poison" and " @entity14039 " been printed in large characters, the examining doctors in the emergency ward would probably not have overlooked the presence of @entity14039 , and the @entity1 would perhaps have been more careful when using it. @entity14039 can be easily obtained by anyone through the Internet, although general consumers could not obtain industrial quantities. Therefore, the number of burn @entity1 who are not familiar with @entity14039 may increase in the future.

Burns caused by dilute XXXX in the bleach.
