Sites of distant metastases mainly include contralateral lung, lymph nodes, brain, bones, adrenal glands and liver; skeletal muscles metastases (SMMs) are less common. Psoas muscle and diaphragm metastases are mainly found during autopsy, as their involvement commonly is asymptomatic. We report a case of a 60-year-old female, suffering from non-small cell lung cancer (NSCLC), with refractory lower back pain, as expression of malignant psoas syndrome (MPS). MPS is a rare and difficult-to-treat cancer-pain syndrome, unresponsive to majority of analgesic therapy, related to psoas muscle metastasis; it is usually caused by different tumors such as uterus, ovary, bladder, prostate, colon-rectum, lymphoma, melanoma and sarcoma and represents an uncommon finding in NSCLC patients.\u00a0<\/jats:p>","DOI":"10.4081\/monaldi.2019.1012","type":"journal-article","created":{"date-parts":[[2019,4,5]],"date-time":"2019-04-05T20:24:47Z","timestamp":1554495887000},"source":"Crossref","is-referenced-by-count":3,"title":["Non-small cell lung cancer presenting as \u201cpsoas muscle syndrome\u201d"],"prefix":"10.4081","volume":"89","author":[{"given":"Mariano","family":"Mollica","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rosalba","family":"Maffucci","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sabrina","family":"Lavoretano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gaetano","family":"Rea","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco Saverio","family":"Cerqua","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luigi","family":"Aronne","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Bianco","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabio","family":"Perrotta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2549","published-online":{"date-parts":[[2019,4,5]]},"container-title":["Monaldi Archives for Chest Disease"],"original-title":[],"link":[{"URL":"https:\/\/www.monaldi-archives.org\/index.php\/macd\/article\/download\/1012\/889","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.monaldi-archives.org\/index.php\/macd\/article\/download\/1012\/889","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,26]],"date-time":"2020-03-26T20:13:00Z","timestamp":1585253580000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.monaldi-archives.org\/index.php\/macd\/article\/view\/1012"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,4,5]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2019,3,29]]}},"URL":"https:\/\/doi.org\/10.4081\/monaldi.2019.1012","relation":{},"ISSN":["2532-5264","1122-0643"],"issn-type":[{"value":"2532-5264","type":"electronic"},{"value":"1122-0643","type":"print"}],"subject":[],"published":{"date-parts":[[2019,4,5]]}}}
