Bilateral upper limb lymphoedema associated with psoriatic arthritis: a case report and review of the literature
Lymphoedema is an unusual extra-articular feature of rheumatoid arthritis and has rarely been described in psoriatic arthritis. We report a 41-year-old man with psoriasis and psoriatic arthritis who developed bilateral lymphoedema of the upper extremities. Lymphoscintigraphy showed absent lymphatic drainage in the right arm and a subnormal increase in lymphatic flow under manual exertion in both arms. Colour Doppler ultrasound studies did not reveal venous or arterial abnormalities. Conservative management and therapy with cyclosporin (for worsening arthritis) resulted in partial resolution of the lymphoedema and improvement of flow parameters on the right side upon repeat lymphoscintigraphy.
