Laboratory Studies

The workup of acneiform eruptions varies greatly, reflecting the wide variety of diseases. This can include skin biopsies, cultures and sensitivities, serologic tests, and empiric trials of drug withdrawal (see Physical Examination).


Histologic Findings

Depending on the eruption, biopsies may demonstrate suppurative folliculitis, eosinophilic folliculitis, keratosis pilaris, or granulomatous dermatitis. [23]
