Eczema On Anal / Genital
Eczematous lesions in the anogenital region may be accompanied by a irritant or allergic contact dermatitis, and a seborrhoeic or atopic dermatitis caused. In practice it is often difficult to focus on a single etiologic factor, because an overlap of endogenous factors (eg, atopic eczema) and exogenous factors (allergens, or irritants) is frequent. An allergic contact dermatitis often through contact with local therapies such as neomycin, local anesthetics, ethylenediamine and creams to treat hemorrhoids, and Treated (eg perfumed) toilet paper and intimate sprays.
Depending on how acute the lesions are seen redness, oozing, erosions, fissures and excoriation to strong lichenification. Burning, stinging or itching often accompany the skin lesions.
Diagnosis:
The diagnosis is based on a thorough medical history to prevent possible irritants or allergens to identify, and a full investigation of the skin. Bacterial and mycological swabs and cultures are recommended to prevent possible infections ruled out. If allergies are suspected, patch testing should be done. A biopsy is useful to non-eczematous skin diseases ruled out.
Differential diagnoses:
Anal / perianal lesions: Psoriasis Inversa, Intertrigo, fungal infections, M. Extramammary Paget, syphilis and Histiocytosis X are possible differential diagnoses.
