[Advanced basal cell carcinoma].

306 patients underwent extensive plastic surgery in the last five years for advanced basal cell carcinoma. In 12 patients either due to delay in presentation or due to inadequate treatment squamous cell carcinoma supervened. In all 12 cases reconstruction was very limited or impossible. Prostheses were used to mask those defects which could not be reconstructed. The infiltrative growth of these squamous cell carcinomas towards the brain could not be controlled. Eventually all the patients developed wide-spread systemic metastases.
