clinic
Since they usually do not cause any symptoms, they are often only discovered by chance when the bone has increased in size. They are often detected in the X-ray image , where they are shadowy and sharply delimited. With their ivory color, they often stand out from the rest of the bone tissue. Under the microscope , mature and completely mineralized bone tissue with layers arranged in lamellae can be seen.
Osteomas can indicate intestinal polyposis ( Gardner syndrome ).
