Photogallery. Pyoderma

Pyoderma is an acute (less often chronic) purulent inflammation of the skin, its appendages, and subcutaneous adipose tissue. Pyodermas are the most common skin diseases, accounting for 30–40% of all skin diseases. According to the etiology, staphyloderma, streptoderma, streptostaphyloderma are distinguished.

Staphyloderma is more common in men aged 45 to 65 years, who are diagnosed with 60–70% of all cases of the disease; streptoderma ― more often in women and children with delicate skin and a thin stratum corneum.

Along the course, pyoderma is divided into acute and chronic; according to the mechanism of occurrence into primary or secondary; according to the depth of the lesion into superficial, deep.

Staphyloderma is usually associated with sebaceous hair follicles; pathogen ― more often Staphylococcus aureus (facultative anaerobe, lives in the mouths of follicles, sebaceous and sweat glands). Streptoderma is mainly caused by β-hemolytic streptococcus (an obligate aerobe, present mainly on smooth skin, near natural openings and folds).
