Where are chondrosarcoma located?

Where are chondrosarcoma located?

Chondrosarcoma primarily affects the cartilage cells of the femur (thighbone), arm, pelvis, or knee. Although less often, other areas (such as the ribs) may be affected. Chondrosarcoma is the second most common type of primary bone cancer. A primary bone cancer is one that starts from bone.

Can you get cancer in thyroid cartilage?

Primary chondrosarcoma of the thyroid cartilage is a rare malignancy. Chondrosarcoma of the larynx is also uncommon, comprising only 1% of laryngeal malignancies (1), of which approximately 20% arise from the thyroid cartilage, the second most common site after the posterior lamina of the cricoid cartilage (2).

What are the muscles attached to the oblique line of thyroid cartilage?

The oblique line is a line on the thyroid cartilage. It marks the upper lateral borders of the thyroid gland. Two muscles originate along the line, the thyrohyoid muscle and inferior pharyngeal constrictor. The sternothyroid inserts along the line.

What type of cancer is chondrosarcoma?

Chondrosarcoma is a type of bone cancer that starts in cartilage cells. Cartilage is the smooth connective tissue that protects the ends of bones and lines most joints. Chondrosarcoma is the second most common type of primary bone cancer in adults.

What is a tumor composed of cartilage called?

Listen to pronunciation. (kon-DROH-muh) A rare, slow-growing tumor that is made up of cartilage and forms on or in bones or soft tissue. It is not cancer.

What is a cartilage tumor?

Cartilage tumors, also known as chondrogenic tumors, are a type of bone tumor that develop in cartilage, and are divided into non-cancerous, cancerous and intermediate locally aggressive types.

Can thyroid cartilage grow?

The thyroid cartilage typically grows larger during the teenage years, especially in boys, and is seen as a secondary sexual characteristic.

What is the thyroid cartilage attached to?

hyoid bone
The thyroid cartilage is the largest cartilage of the larynx and is composed of hyaline cartilage. It sits beneath the hyoid bone to which it connects by the thyrohyoid membrane. Inferiorly it articulates with the cricoid cartilage.

What is the thyroid attached to?

Anatomy Overview The thyroid attaches to the trachea via a consolidation of connective tissue, referred to as the lateral suspensory ligament or Berry’s ligament. This ligament connects each of the thyroid lobes to the trachea.

Where does chondrosarcoma start?

Chondrosarcoma is a rare type of cancer that usually begins in the bones, but can sometimes occur in the soft tissue near bones. Chondrosarcoma happens most often in the pelvis, hip and shoulder. More rarely, it can happen in the bones of the spine.

What does chondrosarcoma look like?

The lytic lesion usually appears well-defined, associated with endosteal scalloping, and cortical thinning or thickening. High-grade tumours show irregular margins. Calcifications of the tumoral matrix may be punctate, flocculent, or have a ring-like pattern, they can be small, or disseminated, dense or subtle.

Can chondrosarcoma metastasis?

Approximately 22%–32% of patients with chondrosarcoma develop metastasis. The rate of metastasis is related to histological tumor grade. Moreover, patients with large tumors, pelvic lesions, high-grade tumors, and local recurrence have been reported to be at high risk for metastasis and poor survival.

What cancers are linked to thyroid cancer?

People who have or had thyroid cancer can get any type of second cancer, but they have an increased risk of developing:

• Breast cancer (in women)
• Prostate cancer.
• Kidney cancer.
• Adrenal cancer.

How often does thyroid cancer spread to bones?

Of the 887 patients with thyroid carcinomas treated at author’s hospital, 44 patients (5.0%) had bone metastases. The overall prevalence rate was similar to previous reports (3.8%–4.2%).7,11 Female patients (75%) were also more common than male (25%) as in previous reports (female, 82.7%; male 17.9%).

What muscles attach to thyroid cartilage?

The internal surface of the thyroid cartilage is covered by a mucous membrane. The angle serves as the attachment point for several laryngeal ligaments and muscles such as the thyroepiglottic, vestibular and vocal ligaments as well as the thyroarytenoid, thyroepiglottic and vocalis muscles.

What is the thyroid cartilage commonly called?

the Adam’s apple
function in larynx … front set of plates, called thyroid cartilage, has a central ridge and elevation commonly known as the Adam’s apple.

When does thyroid cartilage appear?

The thyroid cartilage is a part of the laryngeal cartilaginous complex and may undergo calcification or endochondral ossification (or both), thereby becoming visible radiographically. Usually, ossification is visible only in individuals over the age of 20 years.
