Neutrophilic eccrine hidradenitis heralding the onset of chronic myelogenous leukaemia.

Neutrophilic eccrine hidradenitis was initially described in acute myelogenous leukaemic patients undergoing chemotherapy, suggesting a drug-induced mechanism. It has been reported in some with various neoplastic and non-neoplastic conditions as well as in healthy individuals. However, most the reported cases have been described in acute myelogenous leukaemic cases receiving chemotherapy. We describe a neutrophilic eccrine hidradenitis case unassociated with chemotherapy in a woman with chronic myelogenous leukaemia.
