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 rosacea 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 rosacea is most commonly associated with rhinophyma, an enlargement of the nose. Signs include thickening skin, irregular surface nodularities, and enlargement. Phymatous rosacea can also affect the chin (gnathophyma), forehead (metophyma), cheeks, eyelids (blepharophyma), and ears (otophyma). Telangiectasias may be present. In ocular rosacea, 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 rosacea include:: 689 
Pyoderma faciale, also known as rosacea fulminans, is a conglobate, nodular disease that arises abruptly on the face. Rosacea conglobata is a severe rosacea that can mimic acne conglobata, with hemorrhagic nodular abscesses and indurated plaques. Phymatous rosacea 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. : 693

Treatment
The type of rosacea a person has informs the choice of treatment.
This suggests that the B. oleronius bacteria found in the mites could be responsible for the inflammation associated with the condition." Intestinal bacteria
Small intestinal bacterial overgrowth (SIBO) was demonstrated to have greater prevalence in rosacea patients and treating it with locally acting antibiotics led to rosacea lesion improvement in two studies. Conversely in rosacea patients who were SIBO negative, antibiotic therapy had no effect. The effectiveness of treating SIBO in rosacea patients may suggest that gut bacteria play a role in the pathogenesis of rosacea lesions. Diagnosis
Most people with rosacea have only mild redness and are never formally diagnosed or treated. No test for rosacea 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 rosacea is primarily a facial diagnosis, although it may occasionally appear in these other areas. Classification
Four rosacea subtypes exist, and a patient may have more than one subtype:: 176 
Erythematotelangiectatic rosacea 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.
