Redness of the skin is observed under the following conditions:
- When the brow temperature rises, the skin usually turns slightly pink due to the enlargement of small arteries and arterioles, which increases the heat transfer.
- In people with a labile autonomic nervous system, blushing and redness of the skin can alternate due to fluctuations in tone, and, consequently, blood filling of small arteries and arterioles of the skin.
- With erythrocytosis, the skin acquires a dark-cherry hue, which is associated with an increase in the blood erythrocyte content and specific gravity of the restored hemoglobin.
- On the palms, it is possible to detect bright red erythema in the elevation of the thumb and little finger (the so-called palmar erythema, or "liver palms"), which is observed in chronic liver diseases, systemic vasculitis.
- Hyperemia (reddening) of the skin, especially local, accompanied by pain, increased local skin temperature and swelling, is a classic symptom of the inflammatory process (eg, erysipelas).
- Redness of the skin can be observed with various infectious diseases, such as influenza.
