What is the difference between seb derm and rosacea

Pipkin explains. The absence of acne-like bumps is another big difference. Seborrheic dermatitis may be the most common skin condition to occur along with rosacea. It's estimated that between 25 and 28 percent of those with rosacea also have facial or scalp seborrheic dermatitis. Why does this happen and is there a connection?

Experts don't really know. Derick, MD, a board-certified dermatologist in Barrington, Ill. Both conditions together can cause a number of unattractive symptoms on the face — combined they can create increased redness, discomfort, and crusty lesions.

Treatment depends on your skin type, the severity of the condition and the part of your body where it occurs. Treatment on the face and body may include medications such as antifungal and steroid preparations that reduce inflammation and the build-up of scaling on the skin.

When seborrheic dermatitis appears with rosacea, a safe and effective antifungal alone may often be prescribed because the long-term use of topical steroids is associated with rosacea-like symptoms. This condition is known as steroid-induced rosacea. Treatment of seborrheic dermatitis of the scalp may include medicated anti-dandruff shampoos. Rosacea patients who suspect they may have this disorder are urged to see a dermatologist for diagnosis and appropriate treatment.

Several studies have demonstrated high prevalence rates of H pylori in rosacea patients, some even in comparison with age- and sex-matched controls. Laboratory studies and histopathologic examination via skin biopsy may be needed to differentiate between rosacea and rosacealike conditions.

Common Rosacealike Conditions. Systemic lupus erythematosus SLE is a chronic inflammatory disease that has protean clinical manifestations and follows a relapsing and remitting course. The affected skin generally feels warm and appears slightly edematous. The erythema may last for hours to days and often recurs, particularly with sun exposure. The malar erythema of SLE can be confused with the redness of erythematotelangiectatic rosacea.

Nevertheless, the color of the skin in SLE has a violaceous quality and may show a more abrupt cutoff, especially at its most lateral margins. Marzano et al 15 reported 4 cases in which lupus erythematosus was misdiagnosed as rosacea.

All 4 patients presented with erythema that was localized to the central face along with a few raised, smooth, round, erythematous to violaceous papules over the malar areas and the forehead. This presentation evolved rapidly and was aggravated by sun exposure. The patients were all treated with medication for rosacea but showed no improvement. These patients originally presented with limited skin involvement in the absence of any systemic sign or symptoms of SLE. Dermatomyositis DM is an inflammatory myopathy characterized by varying degrees of muscle weakness and distinctive skin erythema Figure 1 ; however, some patients lack muscular involvement and initially present with skin manifestations only.

Sontheimer16 described criteria for defining skin involvement in DM. With the exception of the heliotrope rash, facial erythema has drawn little attention in prior studies of DM-associated skin manifestations. Therefore, Okiyama et al17 performed a retrospective study on the skin manifestations of DM in 33 patients. The investigators observed that MVE in the seborrheic area of the face was most frequent.
