Summary
Extraosseous osteosarcoma is a rare neck tumor. Surgical resection is the primary treatment, but this case highlights the potential for aggressive recurrence and the need for accurate diagnosis via incisional biopsy.
Area of Science:
- Oncology
- Pathology
- Surgical Oncology
Background:
- Extraosseous osteosarcoma (ESOS) in the head and neck is exceptionally rare, with limited literature documenting such cases.
- This report details a new instance of a large, high-grade ESOS situated in the neck region.
Observation:
- A 74-year-old female presented with a right-sided neck tumor, surgically resected.
- Histopathology confirmed osteoblastic ESOS. Initial PET-CT showed no distant metastasis.
- Adjuvant radiotherapy was administered; however, disease progression was noted in the cavernous sinus within 3 months, leading to death.
Findings:
- Incisional biopsy is crucial for diagnosing ESOS and distinguishing it from other soft tissue tumors that produce bone.
- Complete surgical resection is the current gold standard for treating ESOS.
Implications:
- The case underscores the aggressive potential of head and neck ESOS despite initial treatment.
- Accurate diagnosis and complete resection are vital, but vigilance for recurrence is necessary.
- Further research into adjuvant therapies may be warranted for high-grade head and neck ESOS.

01:26Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:19Veins of Head and Neck
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

01:26Muscles of the Anterior Neck
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...
01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:17Gross Anatomy of Bone
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...

01:19Muscles that Move the Head
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
