Ishikawa T TI - Low doses of anticancer drugs increase susceptibility of tumor cells to lysis by autologous killer cells. HLA class II, neural cell adhesion molecule and B7 were not expressed on the cell surface before or after such treatment. TI - Aesthetic reconstruction of the tip of the nose. The nasal tip is a thin structure, often just 3 or 4 mm thick. Concern has been expressed regarding the seeding of viral DNA, in laryngeal papillomatosis, to other sites in the respiratory tract during treatment.
Controversy exists regarding the concept of seeding by the laser plume.
However, instrumentation and anaesthetic intubation are also strongly implicated in seeding DNA to the proximal respiratory tract. No cases of recurrent laryngeal papillomatosis and subsequent papilloma in the paranasal sinuses have been reported. Chondromyxoid fibroma is a rare benign tumour whose histological appearance may easily be misinterpreted as chondrosarcoma. It has a tendency to recur locally unless completely excised. A rare case of the tumour affecting the nasal bone with extension into the frontal and ethmoidal sinuses and impingement on the cribiform plate is presented.
