Abstract
We report a case of 83-year-old male presenting with the mass composed of clustered bacteria and fungus found in the bilateral Rosenmtiller Fossae.The patient had been complaining of discomfort in the throat for one month prior to visit our hospital.Fiberscopic examination revealed a whitish mass residing in the left Rosenmtiller fossa with caseous appearance and a purulent substance in the right Rosenmtiller fossa.CT scan revealed a nodular mass with some calcification in the left Rosenmtiller fossa. The fiberscopic appearance of the lesion was strongly suggestive of nasopharyngeal carcinoma. However, careful cleaning of the nasopharynx disclosed well-developed Rosenmtiller fossae with normal mucosal surface, and bacteriological and histological examination defined the lesion to be clustered bacteria and fungus.It is speculated that the abnormally wide and deep Rosenmtiller fossae and the age-related reduction of local immunological defense mechanism had offered a good chance to the flora to grow massively.
