What could a bony hard lump on front side of clavicle be?
1. Exostosis: This is a benign bone growth that projects from the surface of the clavicle. It is usually painless and does not require treatment.
2. Subperiosteal hematoma: This is a collection of blood beneath the periosteum, the membrane that covers the bone. It can occur after an injury or trauma to the clavicle and may feel like a hard bump.
3. Osteoid osteoma: This is a benign bone tumor that is characterized by the formation of new bone tissue. It can cause pain and swelling, and may be felt as a hard lump on the front of the clavicle.
4. Infection: An infection of the clavicle, such as osteomyelitis, can cause inflammation, swelling, and pain. In some cases, it may also lead to the formation of a hard lump.
5. Malignant tumor: While less common, a hard lump on the front of the clavicle could also be a sign of a malignant tumor, such as osteosarcoma or chondrosarcoma. These types of tumors typically cause pain, swelling, and other symptoms.
If you are concerned about a bony hard lump on the front side of your clavicle, it is important to see a doctor for evaluation. The doctor can perform a physical examination and may order imaging tests, such as X-rays or MRIs, to determine the cause of the lump and recommend appropriate treatment.
