Loxoscelism (/ l ɒ k ˈ s ɒ s ɪ l ɪ z əm /) is a condition occasionally produced by the bite of the recluse spiders (genus Loxosceles). The area becomes dusky and a shallow open sore forms as the skin around the bite dies . It is the only proven type of necrotic arachnidism in humans.

Spiders do not feed on humans and typically bites occur as a defense mechanism. [20] This can occur from unintentional contact or trapping of the spider. [20] Most spiders have fangs too small to penetrate human skin. [21] Most bites by species large enough for their bites to be noticeable will have no serious medical consequences. [22]
[5] [13] As each bite takes a tiny amount of blood, chronic or severe infestation may lead to anemia. [5] Scratching bites may lead to bacterial skin infection. [5] [14] Systemic poisoning may occur if the bites are numerous. [15] The bite itself may be painful thus resulting in poor sleep and worse work performance. [5]
Other causes of Lymphangitis could be from Arthropod bites and Iatrogenic causes. [4] Lymphangitis is sometimes mistakenly called "blood poisoning". In reality, "blood poisoning" is synonymous with sepsis. Lymphatic vessels are smaller than capillaries and tiny venules and are ubiquitous in the body.
