Recurrent toxin-induced perineal erythema L00.0

Manders SM, 1996

Acute, flat perineal dermatitis with a tendency to relapse, which heals completely if the general condition is undisturbed, leaving behind an edge-emphasized scaly ruff. Group A streptococci, but also Staphylococcus aureus, are mostly detected in the throat swab.

The clinical picture is to be assigned to the clinical pictures caused by streptococcal or staphylococcal toxins.

Childhood (3-6 years)

Suddenly appearing, bright red, laminar, possibly slightly itchy erythema that may cover the buttocks, thigh bends, genitals and perianal region. The raspberry tongue typical of scarlet fever can also occur in the context of toxin-mediated perineal erythema. Group A positive streptococci are almost always detected in throat swabs (Schoeffler A et al. 2012). These can possibly also be detected perianally (see also Perianal Streptococcal Dermatitis). The clinical picture is self-limiting.

2nd generation oral cephalosporins (over 7-10 days).
