Rare systemic diseases such as amyloidosis can mimic inflammatory rheumatic diseases. Because of their poor prognosis, physicians should rule them out at the onset of inflammatory rheumatism. We report a case of AL amyloidosis misdiagnosed as rheumatoid arthritis. ⋯ Amyloid light-chain amyloidosis arthropathy is probably underdiagnosed. A review of amyloid arthropathy associated with multiple myeloma found that 33% of patients had been misdiagnosed with rheumatoid arthritis.

The diagnosis of bilateral papilledema implies emergency medical care to look for intracranial hypertension and arteritic ischemic neuropathy. However, other causes must also be mentioned, including drugs. Too often underrated because of their usual benignity, drug side ophthalmological effects can be severe and are typically bilateral. ⋯ Bilateral edematous optic neuropathy is a known side effect of amiodarone, uncommon but to be known because of the large number of patients benefiting from this treatment.

Spondyloarthritis include articular (axial, peripheral or enthesitic) and extra-articular manifestations. We reported three cases of limb lymphedema associated with a spondyloarthritis. ⋯ Limb lymphedema is a rare extra-articular manifestation of spondyloarthritis. Its course appears to be independent of joint disease. Its management is specific and should be associated to that of the rheumatologic disorder.
