How I manage seborrhoeic keratosis

RSC Leung 梁守中

Abstract
Seborrhoeic keratosis classically presents as longstanding, minimally progressive, well demarcated pigmented keratotic papule or nodule with a 'stuck-on' appearance. Fine clinical features of multiple small keratin or milia-like cyst on granular or cerebriform surface are best seen at dermoscopy. Topical steroid-antibiotic mixture and trauma protection help to relieve the symptoms of irritated seborrhoeic keratosis. Simple curettage followed by electro-desiccation under local anaesthesia is best for treating large truncal lesions. For smaller truncal lesions, cryotherapy is the treatment of choice. Carbon dioxide and Q-switched Nd:YAG lasers as well as intense pulsed light are used for facial lesions. For eruptive lesions, oral acitretin can be used.
