Giant-cell tumour of the tendon sheath. 1981

P K Parekh

An unusual case of giant-cell tumours of the tendon sheath (syn. Pigmented villonodular tenosynovitis or fibrous xanthoma) of a long thumb flexor is presented. The unusual features are: two distinctly different tumours of almost similar size and shape arising from the tendon sheath at its either ends but with a segment of normal tendon sheath in between and presence of early malignant changes in the distal tumour with a benign proximal one, confirmed microscopically. Lastly, radiograph showed definite bony involvement in the proximal phalanx of the thumb. On extensive review of the literature, I found reports of rare presentation of malignant changes and bony erosion, but none had these various features.

D013717	Tenosynovitis	Inflammation of the synovial lining of a tendon sheath. Causes include trauma, tendon stress, bacterial disease (gonorrhea, tuberculosis), rheumatic disease, and gout. Common sites are the hand, wrist, shoulder capsule, hip capsule, hamstring muscles, and Achilles tendon. The tendon sheaths become inflamed and painful, and accumulate fluid. Joint mobility is usually reduced.	Tenosynovitides
