Neutrophilic eccrine hidradenitis (NEH) is a rare neutrophilic dermatosis involving the eccrine glands. It is commonly associated with haematological malignancy and administration of chemotherapy. An infective aetiology for NEH is termed infectious eccrine hidradenitis (IEH). Pathogens that have been associated with IEH include Nocardia, Serratia, Enterobacter sp., Staphylococcus aureus and Mycobacterium chelonae. We describe a case of IEH in a patient with prolonged use of a compression sleeve for their upper limb lymphoedema. The histopathological findings of NEH and IEH are almost identical. Skin tissue culture and rapid clinical improvement with antibiotic therapy are keys in delineating the two subtypes.
