Skin and subcutaneous infections.

Cutaneous infections most commonly are caused by Staphylococcus aureus and GABHS. Life-threatening complications can occur and are preventable with early diagnosis and specific therapy. Dermatophytoses frequently are seen in children and immune-compromised adults with poor hygiene. Sporotrichosis and nontuberculous mycobacteria are ubiquitous and can cause indolent granulomatous lesions. Vesicular and fleshy lesions are manifestations of cutaneous viral infections due to HSV, varicella-zoster virus, molluscum, and human papillomavirus.
