Scabies And Pleva Similarities

Pityriasis Leichenoides et Variolaformis Acuta (PLEVA) is also called Mucha Habermann's disease. It is rarely found and affects the skin causing clusters of small, itchy bumps on the torso or upper extremities. It primarily affects the hands and arms. Since scabies also infects the skin with similar appearing rashes, PLEVA is often misdiagnosed as scabies.

Scabies and PLEVA Similarities:

The eruption of rashes in the skin is usually the first symptom of the disease as in the case of scabies. On healing, it leaves scares which look like spots found in the skin after chicken pox. Like scabies, PLEVA infected patients suffer from excessive itching and burning of the skin. Similarly, these rashes, in general, do not affect the face. Infected patients may also experience low fever, headache, discomfort and joint pain. Sometimes, PLEVA may cause blisters and mouth ulcers.

There is little known about the causes of PLEVA. It is not an infection spread by parasites and sometime is found to occur due to immune disorder. The disease mostly gets cured spontaneously, but in some cases, the infection recurs for many years. The duration of the disease may be longer in adults.

The treatment methods are also quite ambiguous. Antibiotics such as oral erythromycin or tetracycline are generally prescribed but they may not really work in curing PLEVA, hence it is advised to take simple precautions like not touching the affected skin and regulating the moisture in the affected areas. Topical steroids may be administered to reduce irritation. Phototherapy is another recommended treatment using artificial ultraviolet radiation treatment. Systemic steroids or methotrexate may be used to treat severe cases of PLEVA.
