Insect bite dermatitis that tends to be bitten by mites. Insect bite dermatitis is an allergic and inflammatory reaction caused by mites, mosquitoes, bed bugs, fleas, bees and other insects piercing their mouthparts into the body to suck blood, or injecting venom juice into the human body. Sometimes it is difficult to find the bug itself, so it is classified as insect bite dermatitis.

The common denominator is that there is a pin-sized bite mark at the bite site, the skin lesion is the same as the bite site, the itch is unbearable, and the severity is related to the type and number of insects and the sensitivity of the patient. Mite dermatitis is characterized by edematous whealoid papules, papules, or ecchymoses. Mosquitoes are mainly petechiae, wheals, pimples or ecchymoses.

Bug bites may see wheal-like papules or itching,** petechiae and blisters, and may have erythematopura. Flea bites are mainly blistered, erythema multiforme, or purpura, which are found on the waist and legs. Bee stings are mainly painful, quickly red and swollen, and there will be blisters and even bullous damage.

Topical glucocorticoid creams such as hydrocortisone butyrate cream are used in patients with mild symptoms, and antihistamines such as loratadine tablets are used internally, with extensive skin lesions, and oral prednisone in severe cases. Bee stings need to be pulled out immediately, rinsed with water, and actively rescued if necessary.

The reason why mosquito bites turn purple is that there is a vasodilating and anticoagulant substance in the saliva of mosquitoes, which makes it easier for blood to flow to the bite site, resulting in bagging and itching.

Itching occurs when the body's immune system releases a protein called histamine to fight foreign substances, and this immune response triggers an allergic reaction at the bite site. Histamine causes swelling of the tissues around the bite as blood flows to the bite site to speed up tissue recovery.
