Rash

Introduction Creeping eruption, also known as mobile larvae (migrans). More common in the tropics, Southeast Asia is not uncommon, and there are reports in the southeast of China. When the eggs in the feces hatch into infectious larvae, when the human body, especially the child, contacts the larva, it is ill by the skin. Symptoms appear several hours after the larva invades the skin. The larvae begin to consciously and slightly itch, also on the leather surface, and also have a strip-like shape. The mites of the cat hookworm, the hookworm, the horsefly, the horsefly, etc. can be found in the skin lesions.

Cause

(1) Causes of the disease

It is caused by infestation of human skin by aphids of Caenorhabditis elegans (cat hookworm), dog hookworms, and parasitic worms, horses, and horses. When the human body comes into contact with the soil contaminated by feces excretions of cats and dogs containing such aphids, or the uncooked meat containing such aphids, the disease can be caused by such aphids. Subcutaneous or subcutaneous tissue, so skin lesions are more common, occasionally invading the lungs and their internal organs, the aphids of the jawworm can still be parasitic in some freshwater fish and frogs, squid, etc., such as eating these uncooked Fish can also cause illness.

(two) pathogenesis

When the human body comes into contact with the soil contaminated by the feces excretion of cats or dogs containing such aphids, or the uncooked meat containing such aphids, eat these uncooked fish, frogs, squids . This disease can be caused. This kind of aphid is parasitic on the epidermis or subcutaneous tissue of the skin, so the skin lesions are more common, and occasionally the lungs and their internal organs are invaded. The larvae migrate in the lungs, causing an allergic reaction to the worms.

an examination

The skin has a reddish, tortuous, linear lesion, which is slightly raised on the leather surface and has a strip-like shape. The length is uncertain. Generally, the mites move about a few centimeters a day, and the lesions continue to advance, which can be as long as 15 to 20 cm. The old damage can tend to subside, and the mites can move for a few days or even months. Eat these uncooked fish, frogs and squids. Contact with feces of cats and dogs containing such aphids. The mites of cat hookworm, dog hookworm, horsefly, horsefly, etc. can be found in the skin lesions, and the diagnosis can be confirmed.

Differential diagnosis

The disease should be differentiated from hemorrhoids, schistosomiasis, filariasis, schistosomiasis, and dermatitis.

Under certain environmental conditions, the eggs develop into the third stage larvae and begin to infect the human body. Symptoms appear several hours after the larva invades the skin. The larva migrated in the skin and began to consciously itch. It also showed a harder and smaller lumps. As the mites moved under the skin, the skin showed a reddish, tortuous, linear lesion. The micro-uplifted on the leather surface. Striped. The length is uncertain. Generally, the mites move about a few centimeters a day, and the lesions continue to advance, which can be as long as 15 to 20 cm. The old damage can tend to subside, and the mites can move for a few days or even months. Sometimes mites often move with the nails, but they may be infected with suppuration, consciously intermittent tingling or itching, mostly in the exposed parts, but also in the buttocks and vulva.

It can be complicated by Loeffer syndrome, temporary and migratory infiltration of the lungs, up to 51% of eosinophils in the blood, and up to 90% in the sputum. It shows that the larvae migrate in the lungs and cause the body to be allergic to worms. reaction.
