[Hereditary bone tumors].

Abstract

Hereditary bone tumors are rare and result from mutations affecting cell cycle regulation (e.g. retinoblastoma syndrome/RB1 and Li-Fraumeni syndrome/TP53, Gardner syndrome/APC), energy metabolism (enchondromatosis/IDH1/2), complex signaling cascades (multiple hereditary exostoses/EXT1/2) and DNA integrity (Rothmund-Thomson/RECQL4, Werner/WRN and Bloom syndromes/BLM). The majority of syndromes are incompletely understood and can lead to multiple benign tumors, of which some might undergo secondary malignant transformation over time (enchondromatosis: enchondromas, multiple hereditary exostoses: osteochondromas, Gardner syndrome: osteomas) or bone sarcomas, primarily osteosarcomas as primary (Li-Fraumeni, Rothmund-Thomson, Werner and Bloom syndromes) or secondary manifestation (retinoblastoma syndrome) of the disease. Some syndromes additionally predispose to the development of a variety of other malignant tumors during life. Compared to sporadically occurring tumors, syndrome-related neoplasms can differ in the time of manifestation, site and histology, which can help in recognizing a specific tumor predisposition syndrome.
