Seborrheic and Psoriasis

Psoriasis can occur simultaneously with seborrhoeic dermatitis, a more common scalp condition. This combination is referred to as Sebopsoriasis.

Seborrhoeic dermatitis has some differences from psoriasis. Its scale is usually diffuse throughout the scalp, as opposed to the raised, well defined plaques associated with psoriasis. It also tends to localize on the face and front of the chest. When these symptoms are combined with the symptoms of psoriasis, Sebopsorias results.

Sebopsoriasis has a more yellowish, greasy scale than the typical silvery, dry scale associated with psoriasis. It will occur not only on the scalp, but on the face and chest - similar to the pattern associated with that of seborrhoeic dermatitis. It is deeper red in color, has more defined margins, and a thicker scale than seborrhoeic dermatitis alone.
