Brown recluse spider (Loxosceles reclusa) envenomation, known as loxoscelism, can produce a wide range of consequences. The symptoms may range from itching to wound necrosis, which may ultimately result in death.1 Biopsies of loxoscelism wounds show evidence of acute inflammation, hemorrhage, thrombosis, induration, and liquefactive necrosis of the dermis and the epidermis.2 These effects are attributed to proteolytic toxins in the venom that degrade tissue and cause gravitational spreading of the lesion and dysregulated activation of neutrophils, which is suspected to be involved in dermonecrosis.2 Treatment includes early recognition, cool compresses for mild itching, a possible trial of the leukocyte inhibitor dapsone, and hyberbaric oxygen for chronic lesions.1 The resultant wound, especially in the head and neck area, necessitates innovation to maintain the tenants of open wound care including moist wound care, prevention of normal adjacent skin macerat .......
