title: Neutrophilic eccrine hidradenitis: a case report of an unusual annular presentation.
abstract: Neutrophilic eccrine hidradenitis (NEH) is an acute, self-limited, inflammatory neutrophilic dermatosis. It is most commonly described in patients with acute myelogenous leukemia (AML) following chemotherapy. NEH generally presents as erythematous papules and plaques on the head, trunk, and extremities. Histologically, NEH is characterized by a neutrophilic infiltrate surrounding eccrine ducts and coils with occasional necrosis. We describe a case of NEH with an unusual presentation of annular plaques. A search of the literature revealed only one other case report of NEH presenting as an annular eruption.
