title: [Hereditary head and neck tumors].
abstract: Hereditary paraganglioma, Gorlin-Goltz syndrome and Fanconi anemia are among the rare hereditary tumor syndromes of the head and neck. Patients with hereditary paraganglioma often develop multiple tumors of the glomus caroticum and glomus jugulotympanicum. The corresponding genetic defects of the mitochondrial succinate dehydrogenase complex induce autonomous tumor cell growth. In patients with Gorlin-Goltz syndrome basal cell carcinomas and keratocystic odontogenic tumors usually occur much earlier than in patients with sporadic tumors. The associated germline mutations are located in the patched gene which is a modulator of the cell cycle. Fanconi anemia represents a chromosomal instability syndrome which is characterized by early onset of pancytopenia, i.e. bone marrow failure and subsequent development of acute myeloid leukemia and/or squamous cell carcinomas, especially of the head and neck. A total of 13 different gene clusters have been identified in 2 DNA associated complexes which play an important role in DNA repair mechanisms.
