Plane juvenile warts, flat warts.
Self-limiting warts, which are particularly common in children and adolescents.
Almost exclusively children and adolescents. In adults, immunosuppression should be sought.
Infection caused by human papillomavirus types 3, 10, 28, 29 or 40, often triggered by scratching. Since UV-exposed areas of the body are mainly affected, especially the face, it can be assumed that sunlight is also of aetiological significance.
- Flat, 1-2 mm in size, sometimes hyperpigmented, usually multiple and striate papules on the face, dorsum of the hands, distal forearms and legs
- No pigmentation, featureless yellowish background with punctate vessels
- Clinic sufficient
- If necessary, biopsy with HPV typing
Decent marked changes. In addition to ballooned cells in the upper stratum granulosum and stratum corneum, acanthosis, papillomatosis, basket-weave hyperkeratosis and parakeratosis are to be expected.
Despite sometimes years of existence, spontaneous healing is possible within a few days.
