Chondromas may be classified into two  broad types based on their location: enchondromas ([[tumor]] grows within the bone and expands it) and ecchondroma (tumor grows outward from the bone).<ref name=rt>Chondroma. Wikipedia. https://en.wikipedia.org/wiki/Chondroma Accessed on January 4, 2016.</ref>
Chondroma may be classified according to location of the outgrowth into 3 groups that include [[enchondroma]], [[periosteal chondroma]] and synovial chondroma.

Overview

Chondroma may be classified according to location of the outgrowth into 3 groups that include enchondroma, periosteal chondroma and synovial chondroma.

Classification

  • Chondroma may be classified according to location of the outgrowth into 3 groups:[1][2][3]
  • Another classification for chondroma which is used less commonly is based on their anatomic locations:[4][5][6]
