| Abstract: | Objective: To investigate the ultrastructural characteristics of oral malignant melanoma. Methods: Ultrastructure of oral malignant melanoma was observed in 5 cases with tranmission electron microscope. Results: There was plenty of microvilli like projections on the surfaces and typical melanosome in the cytoplasm. The junctions among cells were rarelly seen. In addition, the nucleolous were irregular and the number of them increased. Conclusion: Electron microcope observation may help to determine the malignent degree and metastasis in lymph node. |
