Summary
Diffuse-type tenosynovial giant cell tumor (D-TSGCT) rarely invades the temporal bone from the temporomandibular joint. This report details three rare cases, offering potential surgical insights for similar rare D-TSGCT presentations.
Area of Science:
- Oncology
- Pathology
- Neurosurgery
Background:
- Diffuse-type tenosynovial giant cell tumor (D-TSGCT) is a benign proliferative disease of synovial tissue.
- Involvement of the temporal bone by D-TSGCT originating from the temporomandibular joint (TMJ) is exceptionally rare.
Purpose of the Study:
- To report three rare cases of D-TSGCT originating from the TMJ and invading the temporal bone.
- To discuss the surgical management and outcomes for these rare cases.
- To provide potential surgical strategies for similar rare D-TSGCT presentations.
Main Methods:
- Case series reporting three patients with D-TSGCT.
- Surgical excision of the tumors.
- Post-operative follow-up to assess recurrence.
Main Results:
- Three cases of D-TSGCT originating from the TMJ invading the temporal bone are presented.
- Tumor invasion involved the middle ear, carotid foramen, or temporal lobe in the reported cases.
- Complete surgical removal was achieved in all three cases, with no recurrence observed during follow-up periods of 30, 20, and 7 months.
Conclusions:
- D-TSGCT originating from the TMJ and invading the temporal bone is a rare clinical entity.
- Complete surgical resection appears to be an effective treatment, leading to favorable outcomes.
- This case series may offer valuable surgical insights for managing similar rare D-TSGCT cases.

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...

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
