Adamantinoma of Long Bones OMIM

Description: Adamantinoma of the long bones is a rare, low-grade malignant neoplasm of unknown histogenesis, which affects mainly the tibia of young adults (Keeney et al., 1989). Sozzi et al. (1990) demonstrated a translocation t(7;13)(q32;q14) in a lung metastasis from an adamantinoma of the tibia in a boy who showed the same translocation constitutionally (in normal fibroblasts and lymphoid cells). The identical translocation was found in his normal father. The breakpoint in chromosome 13 was in the same region as that in retinoblastoma (180200). The level of esterase D was normal in the patient and his parents.
