Step 2 CK: Confusing vesicular skin manifestations

Skin manifestations that sometimes confuse us:

1) Dermatitis herpetiformis: It is a skin manifestation of celiac disease (adult and pediatric) - clusters of vesicles, pustules on extensor surfaces of elbow, knees etc.
Treatment:  Gluten free diet and anti-inflammatory drugs (Dapsone, Sulfapyridine)

2) Eczema herpeticum: Infection of eczematous skin by HSV (fluid filled , honey crusted vesicles on red, indurated skin of eczema).
Treatment: Acyclovir, Valaciclovir.

IkaN addition: I know honey crust makes us think of impetigo right away but put the presentation and distribution whenever inferring the diagnosis. I've got a number of questions wrong on the USMLE practice tests because of the honey crust bias.
