Skeeter syndrome (papular urticaria) is a localized severe allergic reaction to mosquito bites, [1] consisting of inflammation, peeling skin, blistering, ulceration and sometimes fever. It is caused by allergenic polypeptides in mosquito saliva , and therefore is not contagious. [ 2 ]
The term papular urticaria [4] is commonly used for a reaction to mosquito bites that is dominated by widely spread hives. Here, papular urticaria is regarded as a symptom of mosquito bite allergy manifested in individuals with one of the other mosquito bite allergies but particularly in those associated with eosinophilic cellulitis.
Furthermore, other clinical differential diagnosis could be from drug eruptions, urticaria, or viral exanthems. [ 9 ] Sometimes, people may require a 3- or 4-mm punch biopsy to exclude herpes gestationis, which is a variant of bullous pemphigoid occurring during or immediately after pregnancy.
Hives, also known as urticaria, is a kind of skin rash with red and/or flesh-colored, raised, itchy bumps. [1] Hives may burn or sting. [ 2 ] The patches of rash may appear on different body parts, [ 2 ] with variable duration from minutes to days, and do not leave any long-lasting skin change. [ 2 ]
The first outbreak of urticaria can lead to other reactions on body parts not directly stimulated, scraped, or scratched. In a normal case, the swelling will decrease without treatment within 15–30 minutes, but, in extreme cases, itchy red welts may last anywhere from a few hours to days.
Several theories have been put forth, however the pathophysiology of pressure urticaria is unknown. [3] Although there isn't an obvious early cutaneous reaction, the time of the reaction following the application of pressure to the skin, the shape of the lesions, and the infiltrating cells observed on histopathologic examination are indicative of a late-phase reaction.

Prurigo nodularis (PN), also known as nodular prurigo, is a skin disorder characterized by pruritic (), nodular lesions, which commonly appear on the trunk, arms and legs. [1]
Allergic contact dermatitis (ACD) is a form of contact dermatitis that is the manifestation of an allergic response caused by contact with a substance; the other type being irritant contact dermatitis (ICD). Although less common than ICD, ACD is accepted to be the most prevalent form of immunotoxicity found in humans. [1]
