Giant Cell Tumor of the Patella Tendon Sheath Presenting as a Painful Locked Knee.

Panagopoulos A, Tsoumpos P, Tatani I, Iliopoulos I, Papachristou D - Am J Case Rep (2015)

Bottom Line: Clinical examination revealed lack of extension by approximately 20°.Histological examination showed a tendosynovial giant cell tumor of the patella tendon sheath.At the latest follow-up, 2 years postoperatively, there was no local tumor recurrence.

ABSTRACT

Background: The giant cell tumor of the tendon sheath (GCT-TS) is a benign proliferative synovial tumor manifesting as an intra-articular solitary nodule. When it involves the infrapatellar fat pad it can present acutely as a painful locked knee.

Case report: A 26-year-old white male presented with a 2-week history of painful locking in his right knee. Clinical examination revealed lack of extension by approximately 20°. To help establish the diagnosis, an MRI scan of the right knee was performed, showing a large (5×4×2 cm), oval, well-circumscribed mass with a low-intensity homogenous signal. The size of the mass prohibited the removal by arthroscopy and we therefore proceeded with an open arthrotomy. Histological examination showed a tendosynovial giant cell tumor of the patella tendon sheath. At the latest follow-up, 2 years postoperatively, there was no local tumor recurrence.

Conclusions: These rare tumorous lesions should be included in the differential diagnosis of painful locking knee, especially in the absence of definite traumatic history.

Mentions: Based on the history, physical examination, laboratory studies, imaging studies, and histologic picture, a diagnosis of giant cell tumor of the tendon sheath (GCT-TS) was confirmed. Clinical follow-up was performed at 3, 6, 12, and 24 months, during which the patient remained totally asymptomatic. Two years post-operatively an MRI confirmed the disease-free condition (Figure 5).
