Chondroma: Symptoms, Diagnosis and Treatment

Chondroma is a bone tumor that is composed of hyaline cartilage. Normally hyaline cartilage is located at the ends of bone where they form joints. In this tumor the cartilage is present inside the bone. The part of bone located close to the joint is usually involved.

The tumor is usually seen between the ages of 20 to 40 years. Affects males and females equally. The most common location of the tumor is the upper part of the humerus or arm bone.

These tumors are of two types

  • those located eccentrically in the bone are called Chondroma (common in large bones)
  • those located in the centre of the bone called Enchondroma

Enchondromas are usually found in the small bones of the hand and feet.

Most usual symptom is the presence of swelling or the sensation of a lump which is fixed to the underlying bone. Pain may appear as the tumor grows and impinges on the surrounding structures. The tumor may remain symptomless and may go undetected. Such tumors may be found when a x ray is taken for some other condition.

Diagnosis is by x rays. X rays show the tumor as an area of decreased density within the involved bone. The remaining bone may be thinned out and expanded.

Treatment of this condition is by surgery. During surgery the whole tumor is removed along with a rim of normal bone. The defect that remains is then filled with a bone graft. If a rim of normal bone is not removed then it is highly probable that the tumor may grow again.

Incidentally discovered tumors that have no symptoms require no treatment except for regular observation.

My compliments to you and your website. It provides the necessary knowledge and guide to bridge the gap caused by the bits of (mis)information given on most sites. Your website provides a short course on the subject. It not only guides the user, it also provides fundamental knowledge for researching the topic. Giving the user a remarkable and unmatched understanding of their topic. An ounce of knowledge makes for a better patient. I've been longing for a website such as yours. A website that is filled with information a layman can use. Its Not too complicated that it discourages the user.

Thank You for bridging the gap for me and for everyone else.
