Abstract:
Infectious eccrine hidradenitis (IEH), which usually manifests as singular or multiple erythematous papules or plaques, is a rare dermatosis involving an infectious agent and histologic findings identical to that of neutrophilic eccrine hidradenitis (NEH). We report a case of IEH in a 24-year-old woman who developed a pruritic, erythematous, papular rash after a sunburn. A culture of a pustule revealed methicillin-sensitive Staphylococcus aureus. Our patient had complete resolution of her rash within 2 weeks of starting amoxicillin and clavulanate. This case of IEH and NEH related to both intense sun exposure and infection supports the hypothesis that NEH is a response to nonspecific stimuli and may occur in many different clinical settings.
