  • Abstract
  • Look Inside

 The surface view of malignant maxillary tumors (squamous cell carcinoma, undifferentiated adenocarcinoma and fibrosarcoma) was observed in detail by means of scanning electron microscope.

 The squamous cell carcinoma and undifferentiated adenocarcinoma showed a disorderly growth pattern. Their cell surfaces were irregular and roughly granulated. Metastasized fibrosarcoma showed abundant collagen fibers with decreased number of tumor cells.

 Intrarterial infusion of 5-FU and BUdR with 60Co irradiation in the maxillary region induced necrosis of tumor tissues. A large number of lymphocytes were invariably noted among the necrotized tumor cells. These lymphocytes were of T-type in appearance and it is probable that these cells might play an important role in acquiring cellular immunity that may lead to the destruction and disappearance of the malignant tumor cells.
