eritematozus

Eritematozus is a term used in some medical texts to describe erythematous skin—redness caused by increased blood flow in the superficial layers of the skin. In English-language medical writing, the standard term is erythematous; eritematozus is a less common variant or translation-based form that may appear in non-English sources or older literature.

Erythema, or an erythematous change, presents as red patches or plaques on the skin or mucous membranes. The redness may be blanchable, meaning it fades with gentle pressure as superficial blood vessels refill, or nonblanching, depending on the underlying vascular change. It is a clinical sign rather than a disease itself, indicating inflammation, irritation, infection, or other processes that increase blood flow to the area.

Common causes include sun exposure (solar erythema), contact dermatitis, eczema or atopic dermatitis, infections (including viral rashes), drug reactions, rosacea, psoriasis, and physical trauma. Erythema can be localized or widespread and may be accompanied by warmth, itching, or discomfort.

Diagnosis is primarily clinical, based on the distribution, history, and associated symptoms. Investigations are guided by suspected underlying conditions. Management targets the cause and may include avoidance of irritants, use of moisturizers, sun protection, and anti-inflammatory treatments such as topical corticosteroids or non-steroidal agents when appropriate. Post-inflammatory erythema can persist after the initial inflammation has resolved.
