Giant Cell Tumor of the Synovial Pod of the Third Toe on the Right Foot: Report of a Case.

BACKGROUND

The giant cell tumor of the tendon pod is a benign neoplasia that can be present in any bone or tendon pod. Its etiology is unknown. Nevertheless, it is related to a chronic inflammatory process. It usually occurs in women between the third and fifth decade as a palpable and painless mass and slow growth, although it can be deformed and lead to limb loss.

CASE PRESENTATION

In this report, we present the case of an 11-year-old male patient, which began on June 21, 2020, with a blunt trauma. An ultrasound was performed, reporting compatible data with synovial sarcoma. Magnetic resonance was requested, with mass evidence in soft tissues in central and planting portions. A surgical procedure with a split and biopsy of the mass was carried out. The specimen was sent to the Pathology Department, leading to a diagnosis of a giant cell tumor of the tendon pod.

CONCLUSIONS

The giant cell tumor of the tendon pod is rare. However, in some cases, it is crucial to consider it as a differential diagnosis. The surgical management of this entity has proven to reduce recurrence rates.
