This report describes an unusual case of verruciform xanthoma of the posterior floor of the mouth that occurred within carcinoma in situ. The significance of this case is described in light of current theories on the etiology and management of verruciform xanthoma.
The authors present an example of mycosis fungoides which was initially diagnosed from a palatal biopsy. The distinctive nuclear morphology of the tumor cells, with a discussion of their diagnostic importance, is presented. The advantages of plastic-embedded formalin-fixed tissue are delineated.
The authors present three cases which created diagnostic problems. The etiology of these is, in the authors' experience, unique and not generally known. It is suggested that this etiology be considered whenever palatal erythema, ecchymoses, or petechiae are seen.
