Presentation
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]
Presents outstanding photographs for virtually every common skin disorder. [books.google.com]
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]
The shape of the hairs or setae enables recognizing the two main moths families involved in accidents: the Megalopigidae family presents thin and plentiful setae throughout the whole body, whereas the Saturnidae family presents less setae, shaped as small [scielo.br]
Entire Body System
- Pain
The sting area was red and painful. The student applied tape to remove the tiny hairs. He washed the area, used a hydrocortisone cream on the site, and took diphenhydramine (an antihistamine). His pain and redness went away quickly. [poison.org]
[…] are intense pain and local edema and erythema, which are not proportional to the observed pain. [scielo.br]
Internationally stings from other caterpillar species can cause varying degrees of pain, itchiness, weal or blister formation, and rarely systemic symptoms such as dizziness, sweating, and abdominal pain. [dermnetnz.org]
Symptoms Symptoms from stinging caterpillars usually include instant pain, with a longer lasting ache and a raised weal that usually soon subsides. [nt.gov.au]
- Swelling
Ice the area down well, as this will aid with swelling and pain. If the swelling persists, then contact a physician immediately as this could be a serious allergic reaction. [sciencing.com]
Veins in the lower legs fail to return blood efficiently, causing pooling of blood and fluid buildup and swelling. This swelling leads to skin irritation, especially around the ankles. [webmd.com]
It can lead to localized pain, erythema, swelling, and warmth. Typical treatment involves appropriate antibiotic therapy. 6 Contusions are usually caused by mechanical injury resulting in hemorrhage beneath unbroken skin. [aafp.org]
Redness, pain, swelling, and itch develop commonly around the tongue and lips. Occasionally the palate, airways, or oesophagus may be affected. [dermnetnz.org]
- Weakness
However, if a person has difficulty breathing or weakness, or feels lightheaded after being exposed to a caterpillar, he or she should go to the nearest emergency room, Brillhart said. [livescience.com]
Feeling very weak or having trouble standing. Not feeling alert or able to think clearly. You may be confused, restless, fearful, or unable to respond to questions. [northshore.org]
Respiratoric
- Respiratory Distress
RESULTS: Twenty-four out of 47 (51%) questionnaires were returned and 10/24 (42%) children showing symptoms of lepidopterism were reported: 8/10 (80%) dermatitis, 5/10 (50%) pruritus, 5/10 (50%) respiratory distress, 4/10 (40%) malaise and/or fever and [ncbi.nlm.nih.gov]
Respiratory distress from inhaling the hairs can be serious. Caterpillars are active from April to late June. Hairs remain toxic throughout the summer but get washed into the soil and are less of a problem over time. [maine.gov]
- Nasal Discharge
In the United States, many forest workers in areas heavily infested with the tussock moth caterpillar (Orgyia pseudotsugata) have experienced itching of the skin and eyes, nasal discharge, cough and respiratory difficulty (Press et al., 1977). [fao.org]
Gastrointestinal
- Nausea
Lepidopterism is a systemic illness that occurs following such contact, and it is typified by diffuse urticaria, upper airway inflammation, nausea, vomiting, headache, and bronchospasm. [emedicine.medscape.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]
Skin

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]

- Skin Rash
(1 inch) Many hairy caterpillars can cause rashes or dermatitis when they come in close contact with the skin. Symptoms range from mild irritation to an intensely itching rash with reddened, inflamed skin. [statebystategardening.com]
Contrary to the popular belief that caterpillar dermatitis can only be caused by caterpillars crawling on bare skin, Wang said that as long as human skin comes into contact with the bristles of a caterpillar, it could cause rashes. [taipeitimes.com]
If these hairs and toxins come into contact with the skin they can cause symptoms. What sort of symptoms do they cause? If the hairs or toxins come into contact with the skin they can cause a very itchy skin rash. [nhs.uk]
The yellowish caterpillars that have black spots and are covered in hairs have been spotted mainly in the northern and central region of the archipelago’s main island of Mahé with people developing skin rash after coming in contact with the stinging hairs [seychellesnewsagency.com]
- Eruptions
Gypsy moth caterpillar dermatitis is a pruritic, papular, urticarial eruption on exposed skin that occurs most commonly after direct contact with the first instar larva of the gypsy moth (Lymantria dispar). [ncbi.nlm.nih.gov]
But that wasn't the case for one woman in Arizona: Her left shoulder quickly erupted in an itchy, red rash after a brush with one of these critters. [livescience.com]
Until last year, gypsy moth populations never approached the size of the 1980-1981 eruptions during which nearly 3 million acres of forest were defoliated and research on rashes began appearing in medical journals. [capecodtimes.com]
- 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]
School A had an enrollment of 320 students, with 135 affected by rashes (an attack rate of 42.2%). School B had 76 out of 300 students affected (an attack rate of 25.3%). The symptoms included pruritic rash and occasional urticaria. [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]
Urogenital
- Kidney Failure
Ghent Lonomia caterpillars (L. achelous and L. obliqua) can affect the blood’s ability to clot and cause brain haemorrhage and acute kidney failure. [fao.org]
