Bilateral synovial chondromatosis in the knee joint with both intra and extra-articular diseases.

Synovial chondromatosis is a rare disease of unknown etiology. It usually occurs unilaterally in the large joints like the knee, but may occur in the shoulder, elbow, hip, ankle and temporomandibular joints. The disease is usually intracapsular, but can also be extracapsular on rare occasions. The diagnosis of synovial chondromatosis is given after an anamnesis, physical examination and radiographic examination. However, the diagnosis is obtained after histological examination of the synovial tissue. We report an unusual presentation of bilateral synovial chondromatosis in the knee joint, with both intra and extracapsular localization. never described in the literature. Although synovial chondromatosis is described as a benign disease, it can be very destructive and debilitating. These lesions can mimic a malignant tumor and present a diagnostic problem.

Neglected rupture of the quadriceps tendon in a patient with chronic renal failure (case report and review of the literature).

Spontaneous ruptures of the quadriceps tendon are infrequent injuries, it is seen primarily in patients with predisposing diseases such as gout, rheumatoid arthritis and chronic renal failure. A 32-year-old man had a history of end stage renal disease and received regular hemodialysis treatment for more than 5 years. He was admitted in our service for total functional impotence of the right lower limb with knee pain after a common fall two months ago. The radiogram showed a ''patella baja" with suprapatellar calcifications. The ultrasound and MRI showed an aspect of rupture of the quadriceps tendon in its proximal end with retraction of 3 cm. Quadriceps tendon repair was performed with a lengthening plasty, and the result was satisfactory after a serial rehabilitation program. The diagnosis of quadriceps tendon ruptures needs more attention in patients with predisposing diseases. They should not be unknown because the treatment of neglected lesions is more difficult. We insist on the early surgical repair associated with early rehabilitation that can guarantee recovery of good active extension.

Bifocal musculoskeletal tuberculosis in upper limb: Unusual case.

Bifocal musculoskeletal tuberculosis is a rare presentation of the disease. The following report documents the case of a 28-year-old Moroccan man presenting simultaneously with a swelling of the palm of the hand and the sternoclavicular joint. The HIV serology and hepatitis (B, C) serology were negative, as well as the tuberculin skin test. The radiographs of both locations were normal. The histopathology confirmed the diagnosis. The antibacillary chemotherapy produces excellent results. It is therefore indispensable to bear in mind the possibility of such atypical presentations of tuberculosis when making a rapid and pertinent diagnosis and prescribing the appropriate treatment.
