A 58-year-old man who had undergone kidney transplantation for chronic kidney failure in 1998 presented with a swelling in the floor of his mouth in June 2004. On transoral examination, a soft, nonpainful mass was observed in the left part of the floor of the mouth. The same lesion was also evident in the ipsilateral submandibular region. Lingual and hypoglossal nerve function was apparently normal, and there was no pathologic secretion from the Wharton duct. A cystic lesion, with regular shape, located anteriorly to an otherwise normal submandibular gland and displacing the sublingual gland was identified on ultrasound. Because the site and characteristics of the lesion were highly suggestive of a ranula, fine-needle aspiration cytology was not planned.
