LocalizationThis section has been translated automatically.
Preferably on the feet (plantae, subungual, interdigital), other parts of the body (when lying on the ground) can also be affected.
Clinical featuresThis section has been translated automatically.
A few days after penetration of the fleas (1-100), formation of inflammatory, moderately painful to pea-sized, reddish, bulging papules or nodes. A black porus (= parasite) often appears centrally. Itching, pressure pain. Complicated are furunculoid abscesses.
The parasite reaches a size of up to 0.5 cm within 7-14 days. The rear end of the flea with the respiratory and genital openings protrudes from the skin. After ejection of the eggs (up to 300 eggs) and the dead flea, a dimple-like depression remains.
More rare are clinical pictures with disseminated strongly itchy papules on the contact surfaces.

General therapyThis section has been translated automatically.
First kill the sand flea with a swab soaked in ether, turpentine oil or paraffin, then remove the sand flea with a needle or fine tweezers. Occasionally an excision is necessary.
