A Case of Acute Myeloid Leukemia-Associated Necrotizing Sweet Syndrome.

Sweet syndrome (SS), or acute febrile neutrophilic dermatosis, is a rare painful skin condition that is characterized by hyperpyrexia, peripheral blood and skin neutrophilia, and edematous skin lesions. Necrotizing SS (NSS) is a severe and locally aggressive condition that histopathologically resembles a necrotizing soft tissue infection. As opposed to necrotizing soft tissue infections, NSS responds to systemic steroids.

Epithelioid hemangioma involving large arteries in the skin.

Epithelioid hemangioma (EH) is a benign vascular lesion, typically consisting of small vascular channels lined by epithelioid endothelial cells and associated with a dense lymphocytic infiltrate with eosinophils. Here, we report a rare case of EH involving large arteries. The patient presented with a 9-month history of an asymptomatic nodule on the forehead, which was thought to be an epidermal inclusion cyst.

Educational Case: Dermatitis Herpetiformis.

Smoking and Risk of Ischemic Stroke in Young Men.

Background And Purpose: There is a strong dose-response relationship between smoking and risk of ischemic stroke in young women, but there are few data examining this association in young men. We examined the dose-response relationship between the quantity of cigarettes smoked and the odds of developing an ischemic stroke in men under age 50 years.

Methods: The Stroke Prevention in Young Men Study is a population-based case-control study of risk factors for ischemic stroke in men ages 15 to 49 years.
