Dermatology - Papular Urticaria ( Bug Bites) 
Papular Urticaria, also known as bug bites, is a skin condition.
Arthropod bites can cause cutaneous reactions that are either inflammatory or allergic in nature. These reactions are characterized by a highly itchy eruption. Patients frequently lack awareness of being bitten. Arthropods have a crucial role in transmitting numerous systemic illnesses.
Papules, either solitary or clustered, often measuring less than 1 cm, appear at the location of the bite within two days and last for more than 48 hours. These papules can take the form of papulovesicles or bullae.
Erythematous macules may also manifest at the sites of bites and often exhibit a temporary nature. Papules can develop vesicles, and there may be the occurrence of massive urticarial plaques. Excoriations are frequently observed and can lead to the formation of painful erosions. These erosions may become infected, and the healing process can result in either excessive or insufficient pigmentation, as well as the formation of elevated or depressed scars. This is particularly true for those with darker skin pigmentation.

The diagnosis is primarily based on clinical examination, and the differential diagnosis includes papular urticaria and allergic contact dermatitis, particularly caused by plants like poison ivy or poison oak.

Administer highly effective topical glucocorticoids for a brief period to alleviate severe itching. Oral glucocorticoids may be administered to treat chronic itching. Administer appropriate care and closely monitor for any other skin infections or systemic diseases that may be transferred by the arthropod.
