Use of artificial eye and conjunctival squamous cell carcinoma.

time of surgery may also cause dissemination of tumor cells in to the circulation leading to distant metastases. The seeding of cancer cells at distant sites can be stimulated by trauma and / or inflammation as damaged tissues provide a fertile soil for the development of metastases from haematogenously disseminated tumor cells. The treatment of tracheostomy site recurrence may require an extended total laryngectomy or high dose radiotherapy if the site was not included in the radiation ports. A method of delivering highdose radiation to the stomal area by implanting iridium applicators in the tracheostomy tube have been described in patients who have received full-course radiotherapy. Since only a few cases have been reported, specific recommendations cannot be provided, but a meticulous surgical technique, isolation of the surgical field with proper placement of drapes, change of instruments and gloves after removal of the specimen may theoretically reduce the risk of neoplastic implantations.
