Persistent painful plaque due to a brown recluse spider bite.
The bite of the arthropod Loxosceles is known to cause subdermal hemorrhage, dermal-epidermal separation, inflammatory infiltrates, as well as occlusion and necrosis of small arterioles. We report a case of a brown recluse spider bite that presented as a chronic painful skin plaque, with the unusual histologic findings of a cutaneous and deep subcutaneous hyalinizing panniculitis and myonecrosis.
