Abstract:
The urological examination includes the inspection of the external male genitals. Harmless normal variants, such as heterotopic sebaceous glands and pearly penile papules must be differentiated from malignant and infectious manifestations. Lichen sclerosus et atrophicus is a frequent connective tissue disease that can lead to functional impairments and an associated high level of suffering for those affected. Both conservative and invasive treatment options are available. Sexually transmitted diseases, such as syphilis, are gaining increasing importance in routine clinical and daily practice due to the increasing incidence in recent years. An early diagnosis and treatment of malignant neoplasms, such as Queyrat's erythroplasia can be carried out by routine inspection of the genital skin.
