Neutrophilic eccrine hidradenitis in the absence of an underlying malignancy.

Abstract

Neutrophilic eccrine hidradenitis is an entity previously reported to occur in association with malignancy and chemotherapy. We report a case of clinical and histopathologic findings characteristic of neutrophilic eccrine hidradenitis occurring without apparent underlying disease. In addition, the only medication this patient was taking was acetaminophen. Neutrophilic eccrine hidradenitis appears to represent a reaction pattern without specificity for underlying disease or inciting agent.
