[Polymyalgia rheumatica and pulmonary cancer: paraneoplastic syndrome].

An 83-year-old lady was admitted for bilateral pain and weakness of the shoulder and hip girdles. These symptoms suggested a Polymyalgia rheumatica (PMR) but there was no response to corticosteroids. A pulmonary adenocarcinoma without any metastasis was then diagnosed. The excision of this tumor was followed by prompt and complete recovery. The erythrocyte sedimentation rate became normal within a few days, also. Such an issue seems to prove that PMR may occasionally be associated with neoplasia. This association appears anecdotal in the literature and remains without clear explanation.
