Median rhomboid glossitis: secondary to colonisation of the tongue by Actinomyces (a case report).
Median rhomboid glossitis is an inflammatory lesion of the tongue, now believed to be secondary to candidiasis. We document a case of median rhomboid glossitis with heavy colonisation by Actinomyces in a 60-year-old male. We propose that Actinomyces, like Candida, induces pseudoepitheliomatous hyperplasia of the mucosa of the tongue and florid inflammatory hyperplasia of the underlying connective tissue, resulting in the characteristic elevated lesion. Actinomyces has not earlier been implicated as a cause of median rhomboid glossitis.
