The lesions of the skin are categorised in benign and malignant.
Benign lesions are the melanocytic naevi, epidermal cysts, haemangiomas, seborrhoic keratoses, veruccae vulgares (warts), lentigo solders (sunspots) but also not common lesions like syringomas, adenomas and benign penile papules.
Malignant lesions are the basal cell carcinoma, the squamous cell carcinoma and it’s precursor actinic keratoses and melanoma. Further not so common cancers are Merkel Cell Carcinoma, Kaposi Sarcoma and cancers of the adnexes of the skin.
Interventional dermatology or skin surgery is the field of dermatology responsible for the treatment of all bening and malignant lesions. This can be done with different ways i.e. Laser (CO2 laser, Pulse Dye Laser and Q-switched Laser 532/1064nm), cryosurgery or classical surgical excision.
Depending on the clinical and dermoscopical appearance of the lesion the appropriate methods are discussed before the intervention.
