Presumed arachnidism. A case report (in Connecticut)

Area of Science:

• Toxicology
• Dermatology
• Arachnology

Background:

• Arachnidism, encompassing venomous spider bites, presents a diagnostic challenge, particularly in regions where certain species are not endemic.
• The brown recluse spider (Loxosceles reclusa) is known for causing loxoscelism, characterized by necrotic skin lesions.

Observation:

• An 8-year-old boy presented with numerous (up to 12) hemorrhagic and necrotic blisters.
• The clinical presentation was ultimately attributed to probable spider envenomation.

Findings:

• The diagnosis of loxoscelism, a specific form of arachnidism, was considered.
• The occurrence of brown recluse spider bites is notably infrequent in the northeastern United States, making this case unusual.

Implications:

• This case underscores the importance of considering uncommon diagnoses in pediatric dermatology, even in non-endemic areas.
• Increased awareness and diagnostic vigilance for arachnidism are warranted in regions with atypical presentations.
• Further research into the geographic distribution and clinical manifestations of spider bites is beneficial.
