Introduction
Introduction The erysipelas-like appearance is the clinical manifestation of erysipelas. Erysipelas is an acute inflammation of the skin and its reticular lymphatic vessels. Occurs in the lower limbs and face. Its clinical manifestations are acute onset, localized flaky rash with clear boundaries, bright red color, and a slight bulge, fading.

Mild abrasions or scratches, injuries outside the head, unclean umbilical cord ligation, vaccination, and chronic leg ulcers can all cause the disease.

Cause
Cause
The pathogen of erysipelas is group A B-type hemolytic streptococcus, occasionally caused by type C or c-type streptococci. It is often invaded by the damaged part of the skin or mucous membrane, and can also be infected by blood. Therefore, factors such as nasal inflammation, nose, ear, and foot solution often become the cause of erysipelas, and the pathogen can lurk in the lymphatic vessels to cause recurrence. Others such as malnutrition, excessive alcohol abuse, gamma globulin deficiency and renal edema can be the triggering factors for erysipelas.

Gram staining and bacterial culture of wounds and damaged swabs, blood anti-chain and blood leukocytes, lower limb erysipelas should be performed on the toe dandruff mycology, facial erysipelas should be performed by paranasal sinus radiography.

Eczema: It is a common inflammatory skin disease caused by a variety of internal and external factors in the epidermis and dermis. It is generally considered to be related to allergies.

Can occur in any part of any age, any season, but often in the winter recurrence or exacerbation of exudation tendency, chronic course, easy to recurrent.
