[Recurrent skin tumors and their surgical management]

Recurrences of basal cell carcinomas and squamous cell carcinomas are possible in cases of radiation before surgical treatment. This inadequacy occurs in general, if the emphasis of the treatment was on the cosmetical point and therefore the necessary radical therapy had been neglected. Furthermore cicatrizing basal cell carcinomas are prone to recurrences, after only a macroscopical tumor extirpation had been carried out. In special cases of epidermal tumor recurrences our dermato-surgical proceedings are demonstrated. The repair of large skin defects, caused by surgical treatment, requires methods of plastic and reconstructive surgery. Should there be any doubt whether the therapy is radical enough, material for microscopical examination should be taken immediately.
