Diaphyseal Aclasis is also known as:
1. External Chondromatosis Syndrome
2. Multiple Cartilaginous Exostoses
3. Multiple Exostoses
4. Multiple Exostoses Syndrome
5. Multiple Osteochondromatosis
Diaphyseal Aclasis is a relatively rare abnormal condition that affects the skeletal system.
Characterized by multiple exostoses or bony protrusions, it is inherited as a dominant trait.
Approximately half of the children of an individual with diaphyseal aclasis display varying degrees of its symptoms.
Evident involvement is diffuse, with the long bones usually affected more severely and more frequently than the short bones.
The malignant change is more frequent compared to the solitary exostosis.
