Initial Symptoms of Anal Eczema

Common symptoms of anal eczema include itching, pain, erythema (redness) around the anus, moisture, and ulceration of perianal skin. The condition is typically confined to the perianal skin, though in rare cases it may extend to the perineum. Itching is often severe and intolerable. The skin frequently remains moist, leading to infiltration and thickening (lichenification), and may develop fissures. In the acute phase, the rash commonly presents as dense, millet-sized papules, papulovesicles, or small vesicles, with an underlying erythematous base.

Before treating anal eczema, it is essential to identify its specific underlying cause. In some cases, anal eczema results from trauma or injury to the perianal skin; topical corticosteroid ointments may provide effective relief for such cases. However, most cases of perianal eczema are associated with underlying anorectal conditions—such as hemorrhoids, anal fistulas, or polyps. Although these conditions are predominantly benign, they can impair anal function, particularly leading to anal incontinence. Only by actively treating the primary disease can eczema and pruritus secondary to anal dysfunction be effectively alleviated.

Eczema generally requires enhanced skin hygiene and care. The affected area may be gently cleansed with plain water, but soap should be avoided, as it may irritate the skin. Patients should wear cotton or other breathable undergarments and trousers, and avoid coarse or abrasive fabrics.
