Tubercular Tenosynovitis of Extensor Tendons of Ankle : A Case Report.

Introduction: India being an endemic region for Tuberculosis (TB) has a high incidence of musculoskeletal TB with various presentations. Tenosynovitis is a rare presentation and few cases have been reported involving the hand and wrist but isolated involvement of extensor tendons at the ankle is even rarer and unreported.

Case Report: Thirty-five-year-old female patient presenting with a dumbbell-shaped swelling over the anterolateral aspect of right ankle with mild dull aching pain.

Peeled off water chestnut in the knee.

Fibroma of tendon sheaths (FTS) is an uncommon soft tissue tumour which arises from the synovial sheath of tendons. We report a histologically proven case with intrarticular 'fibroma of tendon sheath' originating from the joint capsule of the knee, an even rarer entity, in a middle-aged female presenting with knee pain, swelling with limited range of motion. MRI and arthroscopy studies revealed an intra-articular mass originating from the synovial membrane with lobulated contours.
