Seborrheic Dermatitis and Psoriasis are distinct skin diseases but have many similarities that can occasionally overlap into a skin condition called Sebopsoriasis, which I encounter on a daily basis in both my The Woodlands dermatology and Conroe dermatology clinics. Sebopsoriasis is found on the scalp and face and usually occurs when seborrheic dermatitis is not effectively treated. Typically, seborrheic dermatitis begins as small circular plaques in the scalp with areas of unaffected skin. As the seborrheic dermatitis progresses, the plaques can become confluent and the entire scalp can be involved. As the scalp worsens, facial seborrheic dermatitis tends to worsen as well. Sebopsoriasis can be seen on other ares of the body as well. Thus, it is very important to treat Sebopsoriasis in order to return the patient towards the seborrheic dermatitis end of the disease spectrum.
