Hemangioma is a common tumor in the oral and maxillofacial regions, but cases including phlebolith are relatively rare. We encountered a case of hemangioma with a phlebolith of the upper lip. The patient was a 77-year-old man with a tumor of the upper lip. The tumor was resected. It was 6×6×5mm in size, and the phlebolith was 4×3×3mm in size. Histopathological diagnosis indicated cavernous hemangioma.<BR>We analyzed the composition of the phlebolith using a computer aided microanalyzer (CMA) and an energy dispersive spectrometer (EDS). The EDS analysis revealed that the main components of the phlebolith were Ca and P, and the Ca/P ratio was 1.76. By the CMA analysis, neither Ca nor P was detectable in the center of the nuclear-like region of the phlebolith.
