title: [Dermatological manifestations of synovial cysts of the lower limbs (author's transl)].
abstract: Two cases of synovial cysts of the knees are reported. Thier emergeing point located far away from the joint they originate from can make the diagnosis be difficult. Puncture allows to remove synovial fluid and to inject a radio-active iodine compound to realise a cystography. The radiography of the joint demonstrates an already existing joint disease. The atypical aspects of synovial cysts are emphasized on the basis of then two cases such as pseudo-phlebitic, pseudo-arteritic, inflammatory and fistulised. The presentation of synovial cysts of the legs is frequently dermatological. The diagnosis must be suspected in order to avoid a dermatological biopsy.
