title: Cactus bristle implantation. Report of an unusual case initially seen with rows of yellow hairs.
abstract: A 45-year-old man was seen in a hospital emergency room with regularly arranged rows of yellow hairs on his arm. A detailed investigation disclosed the occurrence of cactus bristle implantation from a house cactus. This implantation resulted in a severe acute dermatitis that evolved during a four-week period into a chronic granulomatous foreign-body reaction.
