L. Mupirocin.
M.Fluconazole.
N.Valaciclovir/famciclovir.

Case 4:Staphylococcal infection
A bacterial culture, F, revealed Staphylococcus aureus,C, that was not resistant to methicillin. The rash responded to combination therapy with cephalexin, K, and mupirocin, L.
PUPPP usually begins in the third trimester and is more intensely pruritic than this patient’s rash. Scabies is also more pruritic, and the eruption would be more widespread. Grover disease is characterized by slightly crusted, erythematous, pruritic papules that occur primarily on the trunk of middle-aged and elderly persons. Candida folliculitis is a possibility that would have been ruled out by the bacterial culture.
