Neutrophilic eccrine hidradenitis(NEH) was originally described in 1982 by Harrist et al. in a patient with myelogenous leukemia receiving chemotherapy. Clinically NEH represents various cutaneous manifestations with or without tenderness and pruritus. Histologic examination demonstrates a neutrophilic infiltrate within and around the eccrine gland and degeneration of the eccrine gland structures. Although the pathogenesis and possible cause of NEH remain unknown, it is probably an unusual cutaneous reaction to chemotherapeutic agents. A few cases of infection associated eccrine hidradenitis are found in the literature. We report three cases of neutrophilic eccrine hidradenitis. Two cases were associated with hematologic malignancy. The third case was associated with an infection of Vibrio vulnificus.
