Stinging insects are a frequent cause of local and systemic hypersensitivity reactions, including anaphylaxis. For those with a history of life-threatening anaphylaxis, venom immunotherapy is effective, safe, and can be life-saving. Arachnids are a much less common source of envenomation through bites or stings and are less likely to cause a hypersensitivity reaction. However, recognizing the clinical manifestations when they do present is important for accurate diagnosis and treatment, and, when indicated, consideration of other diagnoses.

In this case report, we discuss a 32-year-old diabetic male patient who presented with right foot pain three days following a spider bite. The foot progressively became swollen, preventing the patient from bearing weight on it. After admission to the emergency department, the examination showed discoloration of the dorsum of the proximal phalanx of the first toe with an open wound and pus. The patient received fluid resuscitation along with a course of metronidazole and levofloxacin. Subsequently, the patient was referred to an orthopedic and podiatric team where he underwent a complete foot fasciotomy. The procedure was successful, and the patient recovered well. This case showcases a rare manifestation of necrotizing fasciitis (NF) and highlights the importance of future research regarding NF and its association with diabetes mellitus.

BugGuide.net is a website where arthropod photographs submitted by the public are identified by professional and amateur entomologists. In April 2023 posts containing \"bitten\" or \"stung\" were reviewed. Of 39 verified bites, 10 were blood-feeding insects. Others included 9 Heteroptera, 6 spiders, 6 lacewings. 110 posts of stings included 44 social Hymenoptera, 33 solitary Hymenoptera, 5 Heteroptera, 20 caterpillars and 4 scorpions. Injury from lacewing larvae, true bugs, solitary Hymenoptera and caterpillars was unexpectedly common.

Here, we present a case of a 55-year-old male, who was admitted with a spider bite, which caused swelling of the hand and painful muscle spasms along with palpitations. The patient made a complete recovery after the administration of intravenous calcium gluconate, followed by oral calcium supplements. Although no specific treatment exists in Sri Lanka for spider bites, calcium supplements can be beneficial for Sri Lankan ornamental tarantula (Poecilotheria fasciata) bites.

Clinicians should be aware of the occurrence of deep vein thrombosis following brown recluse spider bite.

Primary cutaneous blastomycosis is a rare presentation of infection caused by direct inoculation of a wound. We present a 61-year-old male with an extensive history of wound dehiscence and wound care noncompliance after a bite from a brown recluse spider on the left thigh while on vacation in Cape Cod in September of 2020. After antibiotic therapy and culture, treatment involved debridement, split thickness skin grafting, strict wound vacuum-assisted closure care, and oral itraconazole. This brief demonstrates a case of blastomycosis arising from trauma in a non-endemic region for infection and serves as an example of successful management of the longstanding wound.
