[Carcinoma adenoids cysticum--dispensary case]

In the article the dispensary case of carcinoma adenoids cysticum, highly rare disease of the mandibula is discussed. Clinical and an X-ray examinations revealed many similarities of this disease with cystic radicularis. The correct diagnosis could not be set until histopathological findings of the tissue taken at marsupialization were known. 69 years old female patient was further radically treated in the clinical hospital, where the removed mandibula was replaced by the reconstruction plate. In the literature this disease is presented merely as a metastasis. In the conclusion the accurate and complex examination as well as the necessity of the pathohistological examination of each tissue taken at the oral surgery is stressed.
