The symptoms of ARPC typically involve a rash with small, firm papules that are red-brown in color. They may be located anywhere on the body but are most commonly found on the lower legs, trunk and arms. The papules may also be pruritic and have a sandpaper-like texture. In some cases, localized edema, itching and pain may also be present.


ARPC can be difficult to diagnose as its symptoms are similar to other conditions such as eczema or psoriasis. A diagnosis is usually made based on physical examination of the affected area and ruling out other possible causes such as infections, contact dermatitis or allergy testing. A biopsy may also be taken from the affected area for further diagnosis and evaluation.


ARPC does not often respond well to treatment and there is no known cure at this time. However, treatment may include topical corticosteroids or antibiotics if an underlying infection is present as well as antihistamines for itching relief and barrier creams for protection against irritants or allergens which could worsen symptoms. In some cases ultraviolet light therapy may also be recommended as a way to reduce irritation and inflammation associated with ARPC lesions.
