As dermatologists, we are responsible for all diseases and changes relating to the skin and mucous membrane. Traditionally, our field has also included the diagnosis and treatment of sexually transmitted diseases, which have substantially increased again during the past few years. These include for example syphilis and gonorrhoea, diseases caused by chlamydiae, viral diseases, such as condylomata (genital warts) caused by papillomaviruses, and fungal diseases. Please do not hesitate to contact us concerning complaints or questions related to this subject. Many diseases in this field can be treated relatively simply.
