Background: Important new diseases due to bacterial toxins functioning as superantigens have been described with increasing frequency within recent years. Toxic shock syndrome, recalcitrant erythematous desquamating disorder, streptococcal toxic shock-like syndrome, and, most recently, mucocutaneous lymph node syndrome (Kawasaki disease) have been etiologically linked with certain staphylococcal and streptococcal toxins. We describe two patients with a novel clinical presentation of toxin-mediated disease, which shares certain clinical features with mucocutaneous lymph node syndrome.
Observations: Two otherwise healthy young male adults developed recurrent erysipelaslike perineal erythema, which regularly erupted within 1 to 2 days of the onset of acute pharyngitis. Accompanying signs included mucosal changes and acral erythema with desquamation. Throat cultures obtained during the acute episodes yielded toxin-producing Staphylococcus aureus from one patient and toxin-producing Streptococcus pyogenes from the other.
Conclusion: The recurrent nature, age predilection, and clinical presentation suggest that our patients display a unique clinical syndrome due to toxin-producing bacteria.
