Id reaction

Id Reaction

Id reaction (pronounced: /ɪd rɪˈækʃən/), also known as autoeczematization or autosensitization dermatitis, is a secondary skin reaction to a primary infection or inflammatory condition elsewhere in the body. The term "Id" is derived from the Latin word "idem", meaning "the same", and "reaction" from the Latin "reactio", meaning "a response".

Causes

The exact cause of an Id reaction is not fully understood, but it is believed to be an immune response to a variety of triggers. These triggers can include fungal infections, bacterial infections, viral infections, and inflammatory skin conditions such as atopic dermatitis or psoriasis.

Symptoms

Symptoms of an Id reaction can vary, but often include a rash or eczema-like skin changes, itching, and sometimes fever. The rash typically appears on parts of the body distant from the original infection or inflammation.

Diagnosis

Diagnosis of an Id reaction is typically made based on the patient's medical history and a physical examination. Additional tests, such as skin biopsy or patch testing, may be performed to rule out other conditions.

Treatment

Treatment of an Id reaction focuses on managing the symptoms and treating the underlying cause. This can include topical corticosteroids to reduce inflammation and itching, antihistamines to control itching, and treatment of the primary infection or inflammation.
