    ABSTRACT: Retropharyngeal masses are benign or malignant. Because of their location, even the most benign lesion may behave in such a manner as to endanger life by compressing and obstructing the air and/or food passages. The case of an elderly woman whose life was endangered because of excessive hypercarbia, severe dysphagia, weight loss, and excessive daytime sleepiness secondary to a rare retropharyngeal benign mass, a lipoma, is presented. The literature is reviewed, and all the available cases are tabulated.

    ABSTRACT: ObjectivesMagnetic resonance (MR) imaging may provide some information as to the extent and tissue characteristics of a cancerous mass, but the imaging features of lesions in the floor of the mouth have not been sufficiently clarified. MR imaging features of tumescent lesions in this region were characterized, and the differential diagnoses are discussed. MethodsMR images of 12 patients with tumescent lesions in the floor of the mouth (three patients with squamous cell carcinoma, two with adenoid cystic carcinoma, one with hemangioma, one with schwannoma, one with lipoma, and four with ranula) were reviewed. The literature on the imaging features of tumescent disease in the floor of the mouth was searched using the Medline database. ResultsSix types of tumescent lesions in the floor of the mouth are presented. The differential diagnosis through a review of the references is discussed. Malignant tumors were demonstrated as ill-defined masses. MR images were good at showing the internal structures, such as fluid, hemorrhage, fat, nerves, calculus (phlebolith), cholesterol, and keratin, as different signal intensities. Therefore, MR images gave clues for the differential diagnosis. ConclusionMR images presented the distinctive features or the extent of the lesions and were therefore considered useful for a more accurate diagnosis prior to treatment.

    ABSTRACT: Nasopalatine are the most prevalent of non-odontogenic cysts in the oral cavity. Their origin, however, is still a source of controversy. We report the case of a patient with a mass in the anterior half of the hard palate following months of evolution, with a review of the literature.
