Skin tumor surgery
The skin is the largest organ of the human body. Growths on its surface are called skin tumors, which may be benign and malignant. Some of the benign skin tumors are fibromas, dermatofibromas, cysts, warts, atheromas, lipomas, neuromas, etc. They need to be removed if they cause pain and functional impairment, or for aesthetic reasons. The most frequent malignant skin tumors are basocellular carcinoma, planocellular carcinoma, and melanoma; different types of sarcomas appear more rarely. Benign tumors are distinguished from malignant ones on the basis of clinical and pathohistological findings. Tumors are removed under local anesthesia, if possible by elliptical excision and direct closure of the wound by sutures. In the case of larger tumors, the damage must be reconstructed with the use of local flaps or skin grafts.
