Allergic dermatoses—commonly represented by eczema—present with symptoms such as erythema, crusting, and lichenification.
Infectious dermatoses—such as herpes zoster caused by viral infection—manifest as erythematous patches, clusters of vesicles distributed in a band-like (dermatomal) pattern, and varying degrees of pain.
Inflammatory erythematous, scaly eruptions—e.g., psoriasis—appear as erythematous, scaly plaques; removal of the scales reveals a thin, translucent film (the “film phenomenon”), and further scraping of this film results in pinpoint bleeding (the “Auspitz sign”).
