Final answer:
Multiple enchondromas and hemangiomas indicate Maffucci syndrome, a disorder involving benign cartilage tumors and vascular growths linked to endochondral ossification and embryonic hemangioblasts.
Step-by-step explanation:
The condition described by multiple enchondromas and hemangiomas is known as Maffucci syndrome. This rare, non-hereditary disorder involves the growth of multiple enchondromas (benign cartilage tumors in the bones) and soft tissue hemangiomas (non-cancerous growths caused by an abnormal build-up of blood vessels).
Enchondromas develop from sheets of mesenchymal connective tissue during a process called endochondral ossification, where bone forms by replacing hyaline cartilage. Hemangiomas are related to embryonic stem cells called hemangioblasts that originate in the mesoderm, a layer of cells during embryonic development, and can give rise to both blood vessels and pluripotent stem cells.
