title: [Acute necrosis of the skin--a possible result from the bite of a Hobo-spider].
abstract: A 63-year-old male presented with painful erythema and bullae on his left knee. When working on his boat he suddenly felt a burning sensation followed by numbness of the area. The sensation wore off, but was followed by painful erythema and necrosis. A biopsy showed necrosis with sparse inflammatory cells, consistent with a toxic or thermal injury. The lesion did not heal until after 3 months despite intensive local treatment. This course is typical for a bite of a venomous spider, probably a Hobo-spider. Such a spider was recently observed on the coast of the Øresund area where the patient had his boat.
