While there are no direct synonyms for the term "Ollier Disease", it is also referred to as Ollier's disease, Multiple enchondromatosis, or Enchondromatosis with multiple enchondromas. These alternative terms depict the condition's nature and the presence of multiple cartilage tumors. Ultimately, regardless of the synonym used, all these terms describe the same medical condition characterized by the growth of benign bone tumors throughout the skeletal system.
