What are the symptoms of anal eczema

Anal eczema is a skin disease that occurs in the anus. Anal eczema can also occur in different age groups. There are two main types of anal eczema: primary and secondary. Among them, the symptoms of anal eczema are also relatively obvious. There may be symptoms such as discharge.

1. Limited to the skin around the anus, and in some cases may involve the perineum. The itching is unbearable. It is often moist, the skin is infiltrated and thickened, and cracking may occur. In the acute phase, the rash is composed of numerous densely packed millet-sized papules, papulovesicles or small blisters with a flushed base. Due to scratching, the skin lesions may show obvious punctate exudation and small erosions. The center of the lesion is often heavier and gradually spreads to the surrounding area. There are also scattered papules and papulovesicles on the periphery, so the boundaries are unclear. When combined with infection, the inflammation may be more obvious and form pustules, pus oozing out or yellow-green or dirty brown scabs. It may also be combined with folliculitis, furuncle, local lymphadenitis, etc.

2. When the inflammation of acute eczema is alleviated, or if the acute phase is not promptly and appropriately treated and the condition is delayed for a long time, subacute eczema occurs. The skin lesions are mainly small papules, scales and crusts, with only a few papulovesicles or small blisters and erosions. There may also be mild infiltration, and the patient still feels severe itching.

3. Chronic perianal eczema may develop due to repeated attacks of acute and subacute eczema, and may also present as chronic inflammation from the beginning. The skin of the affected area is infiltrated and thickened, turning dark red and pigmented, with a rough surface and covered with a small amount of bran-like scales, or scabs due to scratching. Some cases have varying degrees of lichenification, which is localized and has clear edges. There may also be scattered papules and papulovesicles on the periphery. During acute attacks, there may be obvious exudate. The subjective symptoms also include obvious itching, which often occurs in paroxysms. Because the skin loses its normal elasticity and is more active, it may crack and cause pain in the affected area. The course of the disease is uncertain, prone to relapse, and difficult to heal.
