Palmar and plantar pustulosis elicited by Candida antigen.

Intracutaneous injection of Candida albicans was done on the forearm of 30 patients with palmar and plantar pustulosis. This induced an aggravation of pustular eruptions on the palms and soles in 11 (37%) of the 30 patients. The aggravation occurred only in those patients who had a positive delayed skin reaction to the Candida antigen. It is suggested that a delayed hypersensitivity inflammatory reaction somewhere in the body is attended with an aggravation of palmar plantar pustulosis.
