Staphylococcal scarlet fever associated with staphylococcal enterotoxin M in an elderly patient

초록

Staphylococcal scarlet fever (SSF) is characterized by an exanthem without enanthem, bullae, or exfoliation, and is known to be related to Staphylococcus aureus toxins, especially superantigens. It has been reported in children and young adults. Herein, we report the first case of an elderly patient with SSF caused by staphylococcal enterotoxin M (SEM), associated with otitis externa. The patient presented with maculopapular rashes on both arms, thighs, and abdomen and with erythroderma on the face, ears, neck, chest, and back, all of which was followed by desquamation on the face, ears, and trunk. A culture of ear discharge grew methicillin susceptible S. aureus that was only positive for SEM among the superantigens tested.
