title: Chorioepithelioma presenting as a bleeding gingival mass.
abstract: A case is reported in which a very malignant neoplasm appeared clinically to be a pregnancy tumor or a hemangioma. There was, of course, no question as to the cause of death in this particular case. It was of interest because of the rarity of the tumor, the metastasis to the oral cavity, and the fact that the final diagnosis was established from pathologic examination. The case demonstrates, with emphasis, the great importance of biopsy and routine pathologic examination of all tissue for accurate and correct diagnosis, regardless of its clinical appearance.
