Seborrhoeic psoriasis (Q91617): Difference between revisions

Seborrhoeic psoriasis (“sebopsoriasis”), so called because of its similarity in morphology and anatomical distribution to seborrhoeic dermatitis, may occur either in isolation or associated with plaque psoriasis elsewhere. Sites of involvement are the nasolabial folds, medial cheeks, nose, ears, eyebrows, hair line, scalp, pre-sternal and interscapular regions. Characteristically the lesions are thin, red and well-demarcated though in some cases they can be recognised as a form of psoriasis only by their association with more typical psoriasis elsewhere.
