Glossary for Itchy rash
Medical terms related to Itchy rash or mentioned in this section include:
- Actinic prurigo: An inherited tendency to develop an itchy, bumpy rash on exposure to the sun. Generally only the face and lips are affected. Symptoms tend to occur seasonally.

- Asian Dendorlimus pini caterpillar poisoning: A chronic illness caused by contact with certain a poisonous caterpillar called Dendorlimus pini. Contact with the cocoon can also cause symptoms. These caterpillars can be found in Asia, north Africa and eastern Europe.
- Bamboo hair syndrome: A rare inherited condition characterized by abnormally formed hair shafts and a skin condition involving scaling and redness of the skin. Patients are also predisposed to developing allergic conditions such as asthma and eczema and food allergies. The severity of the condition can vary with some infants having a poor prognosis due to severe allergies, infections and skin problems whereas others have milder symptoms and fewer allergic manifestations.
- Benign mucosal pemphigoid: A rare chronic disease involving blistering and scarring of the mucous membranes especially in the mouth and conjunctiva of the eye.
- Blisters: Blistering of the skin.
- Body symptoms: Symptoms affecting the entire body features.
- Brain symptoms: Symptoms affecting the brain
- Candidiasis: Fungal infection of moist areas such as mouth or vagina
- Cercarial dermatitis: A short-lived rash that occurs as an allergic reaction to larval (cercariae) infection of the skin. These particular parasites use birds and animals as their first hosts. Larval eggs are excreted in the faeces and when they land in water, they hatch into larvae which then infect certain aquatic snails. The infected snails release another form of the larvae called cercariae which then search for a bird, mammal host. When they enter the skin of a human they die as humans are unsuitable hosts but the skin can produce an allergic reaction.
- Chickenpox: Common viral infection.
- Chilblain: Skin inflammation usually in cold weather
- Comel-Netherton Syndrome: A rare inherited condition characterized by abnormally formed hair shafts and a skin condition involving scaling and redness of the skin. Patients are also predisposed to developing allergic conditions such as asthma and eczema and food allergies.

- Fire coral larvae envenomation: The tiny stinging larvae of fire coral can release a toxin if they are put under pressure. Thus, any larvae trapped under swimming bathers or caps can cause toxins to be released. The skin develops an allergic response to the toxin and a rash forms. Swimming clothes contaminated by the stinging cells can produce a reaction even weeks after they have been washed and dried as the toxins are still able to be released from trapped stinging cells. Rubbing, showering in fresh water and wearing contaminated bathing suits for a long time after getting out of the water tend make the rash worse. Symptoms other than those involving the skin may occur occasionally. The condition most often occurs in places such as Japan and Eastern Russia.

Arthritis, which can be severe, is associated with the psoriasis in up to a third of cases. Not all patients who are susceptible to the condition will develop it - roughly 10% of those susceptible will actually develop the condition. There are various environmental factors which can trigger the onset of the disease e.g. strep throat (common trigger), some medication, stress and cold weather.

Swimming clothes contaminated by the stinging cells can produce a reaction even weeks after they have been washed and dried as the toxins are still able to be released from trapped stinging cells. Rubbing, showering in fresh water and wearing contaminated bathing suits for a long time after getting out of the water tend make the rash worse. Symptoms other than those involving the skin may occur occasionally.

The rash forms on the skin covered by the bathing suit and is caused by an allergic response to stinging cells from the larvae of certain sea anemones and thimble jellyfish which become trapped under the bathers. Stings are most likely to occur in summer. Swimming clothes contaminated by the stinging cells can produce a reaction even weeks after they have been washed and dried as the toxins are still able to be released from trapped stinging cells.

Thus, any larvae trapped under swimming bathers or caps can cause toxins to be released. The skin develops an allergic response to the toxin and a rash forms. Swimming clothes contaminated by the stinging cells can produce a reaction even weeks after they have been washed and dried as the toxins are still able to be released from trapped stinging cells.
