Leukemia cutis and eccrine squamous syringometaplasia


Eccrine squamous syringometaplasia (ESS) is a histological term describing a mature squamous metaplasia of the eccrine ducts. Eccrine squamous syringometaplasia is not an infrequent histological finding and may be associated with chemotherapy or with a variety of non-specific conditions including infections, neoplastic conditions, and inflammatory skin diseases. We report a 75-year-old man who developed ESS within lesions of leukemia cutis (LC). The patient had an inaugural diagnosis of acute myeloid leukemia (AML) and he was not on chemotherapy when the biopsy was performed.
