Typical BPDCN lesion of a sun-exposed area. A 67-year-old man presented with a persistent facial/check lesion, characterized as a violaceous maculopapular skin abnormality with a central necrotic area. Originally suspected to be likely melanoma by visual exam, which would have been a much more common entity appropriately fitting the setting, the abnormality instead confirmed a diagnosis of BPDCN through biopsy.
