It appears you have seborrhoeic dermatitis as the primary problem. LSC, if you have, is the secondary change, which has resulted from repeated and continual scratching. Topical steroids are the mainstay for treating lichenified lesions. However, one must try to control seborrhoeic dermatitis by non-steroidal medicines. These include ketoconazole, metronidazole, etc. The selection will depend upon the severity and extent of the disease and presence of other comorbid conditions. Once controlled, maintenance therapy may be required and the use of steroids may then become only occasional.
