Sebopsoriasis is an overlap between two separate conditions: seborrhoeic dermatitis and psoriasis, in which features of both conditions co-exist. It can be thought of as a transitional condition between seborrhoeic dermatitis and psoriasis and has features of both conditions. It can also be seen across all age groups but is most common in childhood/adolescence and then increases in patients older than 50 years of age.
Like seborrhoeic dermatitis and psoriasis, the pathogenesis of sebopsoriasis is not fully understood.
The treatment for sebopsoriasis has overlap between the treatment for seborrhoeic dermatitis and that of psoriasis. Sometimes the response to treatment can help to determine if the patient is principally suffering from seborrhoeic dermatitis or psoriasis.
