What Is Cellulitis?
Cellulitis is an infection of the skin and deep underlying tissues. Group A strep ( streptococcal ) bacteria are the most common cause. The bacteria enter your body when you get an injury such as a bruise, burn, surgical cut, or wound.

Your health care provider may take a sample or culture from your skin or do a blood test to identify the bacteria causing infection. Treatment is with antibiotics. They may be oral in mild cases, or intravenous (by IV) for more severe cases.
Pathophysiology, Underlying Causes & Clinical Presentation
Pathophysiologically, Cellulitis (ICD-10 L03.90) is driven by or latent viral in Cellulitis (L03.90: reactivation within sensory); Cross-referenced with NIH MeSH (Cellulitis), specialists in Bacterial, Viral & Fungal Infections monitor Targeted PCR / in Cellulitis (L03.90: Culture & Sensitivity) to gauge tissue recovery.
Common Symptoms & Clinical Signs
- • Swollen glands or lymph nodes
- • A rash with painful, red, tender skin. The skin may blister and scab over
- • Presentation of Cellulitis (L03.90): sore throat, productive in Cellulitis (L03.90: cough, sinus/ear pain,)
- • Secondary Cellulitis clinical sign: painful vesicular rash in Cellulitis (L03.90: in a dermatomal)
