Patients with skin conditions, including male genital dermatoses, commonly present to their GP. They range from localised problems in the genital area to being part of a more generalised skin disorder. Penile dermatoses frequently affect men's physical and psychological wellbeing, with a deleterious effect on sexual function. They are usually benign, but can be premalignant and associated with a risk of penile cancer. Although rare, penile cancer has a high morbidity and mortality rate. This article reviews the clinical features of the important penile dermatoses for GPs, provides guidance on how to differentiate between benign and malignant dermatoses, advises on treatment options, and defines criteria for secondary care referral. Skin disorders are the most common reason for GP attendance in the UK (Schofield et al, 2011). Male genital dermatoses can be localised lesions and rashes, such as genital lichen sclerosus, or a manifestation of more generalised skin disease, such as psoriasis. The incidence and prevalence of male genital skin diseases are unknown. It is important to diagnose lichen sclerosus and penile pre-cancerous conditions, both of which are uncommon. A broad understanding of those dermatoses helps recognition and management, including appropriate referral to secondaiy care. Starting treatment promptly not only improves patients' physical, psychological and/or sexual wellbeing, but also can prevent progression of disease (Arya et al., 2013). This holds especially taie for pre-cancerous conditions and neoplastic lesions of the penis, where early recognition and onward specialist referral is crucial.
