A case of lipoma which had developed in the 45 ulobuccal transitional portion of a 90-year-old man was reported. In addition to clinical findings, optical and electron microscopic observations, an EDX qualitative spot analysis was applied to the tumor. Optical microscopy: The tumor was covered with fibrous connective tissues and internally characterized by a complete increase in mature lipoma. Scanning electron microscopy; global lipocytes showed a stone-wall structure, and these cells were enclosed by ivy-like collagen fibers. Transmission electron microscopy: Tumor cells showed a membranate structure and the development of organelles in cells was heardly observed. EDX qualitative spot analysis: In an analysis of tumor cell membrane, the main constituent elements of the tumor were Cl, S, Ca, P and Mg, and in the liposome, the main constituent elements of the tumor were Si, Cl, S and Ca. For one year after the operation, these has been no recurrence of the lesion.
