How is frictional lichenoid eruption treated?
Frictional lichenoid eruption primarily affects preschool-aged children and is likely associated with substances they frequently contact—such as soil and sand—hence its colloquial name, “sand dermatitis.” It commonly occurs on the dorsal hands and forearms.

How is frictional lichenoid eruption treated?
1. General management: Eliminate the underlying cause and avoid unnecessary external irritants. Systemic treatment: For pruritus, oral antihistamines may be prescribed—e.g., cetirizine, loratadine, ebastine, or desloratadine.
2. Topical treatment: Topical corticosteroids—including alclometasone dipropionate ointment, hydrocortisone butyrate ointment, and calamine lotion—may be applied.

This condition is self-limiting. However, repeated exposure to the original irritant may trigger recurrent episodes; therefore, maintaining good hygiene is essential to minimize recurrence.

Frictional lichenoid eruption predominantly occurs during summer and autumn, especially in preschool-aged children aged 2–5 years, with a higher incidence among boys. Lesions typically appear on the dorsal hands, wrists, and forearms, though they may also involve the elbows, buttocks, and knees. The rash consists of pinhead- to millet-sized papules, pale red or skin-colored, sometimes slightly lichenified, occasionally with mild scaling—no vesicles or exudation are present. Lesions are usually symmetrically distributed but may be irregularly scattered. Symptoms are typically absent or limited to mild pruritus. The disease course is self-limiting, with spontaneous resolution occurring within 4–8 weeks. During summer and autumn, parents should exercise extra caution when children play outdoors—avoiding contact with sand and other abrasive materials to reduce mechanical friction. Bedding and clothing for infants and toddlers should be made from soft, non-irritating fabrics. We hope this information is helpful.
