[Focal mucosal hyperplasia of the appendix (author's transl)].

On a 20-year-old male patient and on a 67-year-old female patient, we incidentally detected as histologicbioptic findings after routine appendectomy a focal mucosal hyperplasia of the appendix. Basing on these cases we give a survey on the literature pertaining to these rate cases of mucosal alterations of the appendix published up to now, and discuss the problems of these mucosal hyperplasias.
