Why Are There Tiny Grain-like Bumps on My Babys Hand? How Should They Be Treated?

If a child aged three to five or six years old has small bumps on their wrists with mild itching, it is suspected to be frictional lichenoid eruption, also known as childhood papular dermatitis or sand dermatitis. It is recommended to use ointment as prescribed by the doctor. This is a type of papular dermatitis that often occurs on the wrists, forearm, and other locations of children, which may be a non-specific skin reaction to external stimuli. It is generally believed that this condition occurs when children come into contact with certain objects or mechanical friction, such as playing with sand or toys. As children are active and have poor self-control, they may not pay attention to the way and posture of contact, resulting in frequent contact between exposed skin and frictional substances like sand and toys, leading to the development of a rash. Frictional lichenoid eruption is a common skin disease in preschool children during the summer and autumn seasons, with boys being more affected than girls. It is a non-specific skin reaction of children to external stimuli, manifesting as a temporary traumatic non-specific inflammatory reaction with scattered small papules on the wrists, forearms, elbows, and knees of the affected child, sometimes accompanied by mild lichenoid changes.

1. Pay attention to personal hygiene, maintain clean and dry skin, choose cotton close-fitting clothes, and avoid scratching, squeezing, etc.

2. Avoid frictional irritants such as sand. For preschool children, it is recommended to provide more supervision and reduce the opportunity for mechanical friction.

3. Relieve worries, enhance confidence, and avoid negative emotions that may trigger or worsen the condition.
