Isolated Flexor Tenosynovitis as the Sole Manifestation of Rheumatoid Arthritis: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Chronic volar wrist swelling is a diagnostic challenge, particularly in tuberculosis-endemic regions, where both infectious and inflammatory causes must be considered. Rheumatoid tenosynovitis, an extra-articular manifestation of rheumatoid arthritis (RA), can mimic infectious tenosynovitis, especially in seronegative patients. Case Report: We report a case of a 44-year-old male presenting with progressive pain and swelling over the volar aspect of the right wrist for 2 months. Clinical findings of a local rise in temperature, tenderness, and limitation of range of motion suggested flexor tendon tenosynovitis, with differential diagnoses including abscess, tuberculous tenosynovitis, Giant cell tumours, or inflammatory arthritis. Ultrasound and magnetic resonance imaging revealed tendon sheath thickening and features of median nerve compression. The patient had elevated inflammatory markers, but rheumatoid factor and anti-cyclic citrullinated peptide were negative. Excision biopsy and synovectomy with median nerve decompression were performed. Surgical exploration revealed hypertrophied synovium around the flexor tendons. Histopathology confirmed a rheumatoid nodule, establishing the diagnosis of rheumatoid tenosynovitis despite negative serology. The patient's recovery was uneventful postoperatively. Conclusion: This case highlights the importance of considering rheumatoid tenosynovitis in the differential diagnosis of chronic wrist swelling, even in seronegative individuals. In ambiguous cases, surgical intervention not only alleviates symptoms but also allows for definitive diagnosis through histopathology. A multidisciplinary and vigilant approach is crucial to prevent misdiagnosis and preserve hand function in such presentations.
