Caterpillar Dermatitis

Caterpillar Stings


Presentation

  • We present the case of two brothers with typical skin lesions of leptidopterism.[ncbi.nlm.nih.gov]
  • We present two case reports to illustrate its clinical and histopathologic features. Both cases occurred during the spring of 1990 and coincided with the greatest infestation of L. dispar in the Northeast to date.[ncbi.nlm.nih.gov]
  • In patients presenting with skin reactions and dermatitis of unknown cause, particularly recurrent rash, a careful history of location and seasonality is required.[mafiadoc.com]
  • Found on caterpillar dermatitis Type: Term Definitions: 1. allergic contact dermatitis resulting from a toxin present in hairs and larva of the brown-tail moth, gypsy moth, and other caterpillars.[encyclo.co.uk]
  • Case presentation A 65-year-old man presented with complaints of pruritus in both forearms. He had come in contact with pine processionary caterpillars.[casereports.bmj.com]
Nausea
  • Contact with the hairs causes a painful, swollen rash and sometimes nausea in humans. Source: Wiki La oruga de la ensillada, Acharia stimulea (anteriormente Sibene stimulea), es la larva de una especie de polilla nativa del este de Norteamérica.[thebiologistapprentice.com]
  • Fever, nausea, vomiting, diarrhea, and chills were seldom reported. The rash was generally located on exposed areas of the body--75.4% on arms, 22.8% on the neck, and 21.1% on legs.[cdc.gov]
  • The sting transmits venom which causes burning pain, headache, nausea, or vomiting. Over the next few days widespread bleeding occurs into the skin, mucous membranes, lungs, brain, or kidneys. This can be fatal, but antivenom is available.[dermnetnz.org]
  • Common symptoms include: [8] Itchiness and contact dermatitis, blisters, weals (welts), small red bumps, pain Acute conjunctivitis, if hairs penetrate the eyes Rash and hives Difficulty breathing Nausea and vomiting Bleeding and renal failure can occur[wikihow.com]
  • In Trinidad and Tobago, the hairy moth (Hylesia metabus) is considered a major public health problem, causing severe dermatitis as well as allergic reactions, breathing problems, fever, headache, nausea and conjunctivitis.[fao.org]
Cheilitis
  • . * allergic cheilitis * oral lichen planus caused by metals, acrylics[books.google.de]
Eczema
  • Atopic dermatitis, or eczema, causes the skin to itch, scale, swell, and sometimes blister. This type of eczema usually runs in families and is often associated with allergies, asthma, and stress.[webmd.com]
  • In some cases, contact urticaria can be demonstrated only on damaged or previously eczematous skin, and it can be part of the mechanism responsible for maintenance of chronic eczemas ‎ Pagina 416 - Loveless SE, Ladies GS, Gerberick GF, et al. (1996) Further[books.google.ro]
  • Reactions range from mildly itchy, papular urticaria (small red bumps and swelling) that resolves within an hour; to moderately itchy, urticarial , scaly , blistering, or widespread eczema -like reactions that can persist for weeks.[dermnetnz.org]
  • Studies have shown that allergic diseases such as asthma, rhinitis and eczema have increased fourfold over the past 30 years, particularly in developed countries (Davies, Rusznak and Devalia, 1998).[fao.org]
Pruritic Rash
  • Caterpillar dermatitis should therefore be taken into consideration in the differential diagnosis of a pruritic rash in infants from regions with caterpillar-infested trees, especially during the larval development of T. processionea .[ncbi.nlm.nih.gov]
  • The symptoms included pruritic rash and occasional urticaria. Fever, nausea, vomiting, diarrhea, and chills were seldom reported. The rash was generally located on exposed areas of the body--75.4% on arms, 22.8% on the neck, and 21.1% on legs.[cdc.gov]
Excoriation
  • Morphologically, it is strophulus-like and consists of papulous, excoriated, and pinkish lesions on an oedematous base. Diagnosis is usually straightforward.[ncbi.nlm.nih.gov]

Workup

Lymphocytic Infiltrate
  • The skin histology of caterpillar exposure typically shows epidermal oedema, superficial perivascular lymphocytic infiltrate and eosinophils. 3 Eczematous reactions are typically treated with mild-to high topical steroids.[casereports.bmj.com]

Treatment

  • After 1 day of treatment, skin lesions decreased and pruritus disappeared. A near complete disappearance of erithematous plaques was observed at 2 days of treatment ( figure 1B ).[casereports.bmj.com]
  • Rash improved with symptomatic treatment for 5 days. includes insect bite, contact dermatitis, atopic dermatitis, impetigo and erysipelas. Outbreak of rash caused by caterpillar has been reported in children.[mafiadoc.com]
  • Treatment of affected skin by itchy caterpillars includes the removal of all affected clothing. Apply a piece of adhesive tape to the affected areas and pull the tape off immediately.[nt.gov.au]
  • Stay on top of the latest procedures and treatment guidelines with updated coverage of 184 topics, including Swimmer’s Ear, Dental Pain, Broken Rib, Locked Knee, Puncture Wounds, and Sunburn. Get procedural sedation recommendations from Dr.[books.google.com]
  • Treatment involves removing the hairs or spines from the skin, then treating the symptoms. To treat a caterpillar exposure: If the caterpillar is on the skin, remove it without using your hands![poison.org]

Pathophysiology

  • The pathophysiology of envenomation by Lomomia is still not completely clear.[scielo.br]

Prevention

  • Identification of the caterpillar or moth with pictures or taxonomic keys is essential in the prevention and control of stinging and itchy caterpillar infestations.[nt.gov.au]
  • Preventing caterpillar exposures can be difficult, as they often are feeding on the underside of leaves. Wearing a hat and gloves while gardening can help. Symptoms occur when the setae or spines contact human skin.[poison.org]
  • If the person has blood flow problems, decrease the time ice is used to prevent possible damage to the skin. After several ice treatments, apply a paste of baking soda and water to the area.[medlineplus.gov]
  • Until last year, there hadn't been a major gypsy moth caterpillar outbreak in the U.S. since the 1980s, and states like Massachusetts, Illinois, and Rhode Island are seeking solutions to prevent the insects from harming the environment as well as people[countryliving.com]
  • If accidental contact is made, immediate washing of that area with warm soapy water can help prevent or limit a repeat dermatitis flare.[dermaharmony.com]
