Most people with<unk>  have only mild redness and are never formally diagnosed or treated. No test for<unk>  is known. In many cases, simple visual inspection by a trained health-care professional is sufficient for diagnosis. In other cases, particularly when pimples or redness on less-common parts of the face is present, a trial of common treatments is useful for confirming a suspected diagnosis. The disorder can be confused or co-exist with acne vulgaris or seborrheic dermatitis. The presence of a rash on the scalp or ears suggests a different or co-existing diagnosis because<unk>  is primarily a facial diagnosis, although it may occasionally appear in these other areas. Classification<unk>  on the face Micrograph showing<unk>  as enlarged, dilated capillaries and venules located in the upper dermis, angulated telangiectasias, perivascular and perifollicular lymphocytic infiltration, and superficial dermal edema. Four<unk>  subtypes exist, and a patient may have more than one subtype: # Erythematotelangiectatic<unk>  exhibits permanent redness (erythema) with a tendency to flush and blush easily. Also small, widened blood vessels visible near the surface of the skin (telangiectasias) and possibly intense burning, stinging, and itching are common. People with this type often have sensitive skin. Skin can also become very dry and flaky. In addition to the face, signs can also appear on the ears, neck, chest, upper back, and scalp. # Papulopustular<unk>  presents with some permanent redness with red bumps (papules); some pus-filled pustules can last 1–4 days or longer. This subtype is often confused with acne. # Phymatous<unk>  is most commonly associated with rhinophyma, an enlargement of the nose. Signs include thickening skin, irregular surface nodularities, and enlargement. Phymatous<unk>  can also affect the chin (gnathophyma), forehead (metophyma), cheeks, eyelids (blepharophyma), and ears (otophyma). Telangiectasias may be present. # In ocular<unk> , affected eyes and eyelids may appear red due to telangiectasias and inflammation, and may feel dry, irritated, or gritty. Other symptoms include foreign-body sensations, itching, burning, stinging, and sensitivity to light. Eyes can become more susceptible to infection. About half of the people with subtypes 1–3 also have eye symptoms. Blurry vision and vision loss can occur if the cornea is affected. Variants Variants of<unk>  include: * Pyoderma faciale, also known as<unk>  fulminans, is a conglobate, nodular disease that arises abruptly on the face. *<unk>  conglobata is a severe<unk>  that can mimic acne conglobata, with hemorrhagic nodular abscesses and indurated plaques. * Phymatous<unk>  is a cutaneous condition characterized by overgrowth of sebaceous glands. Phyma is Greek for swelling, mass, or bulb, and these can occur on the face and ears.
