[W-shaped napkin rash in infants (author's transl)].

The W-shaped napkin rash affects mainly the convex parts of the perianal region of infants, avoiding the fold and perianal cleft. The dermatitis is of traumatic origin due to the friction of paper napkins. It heals under antiseptic treatment on condition that the use of paper napkins and rubber pants, which cause occlusion is stopped temporarily.
