There was a female predominance (79%). The mean age was 50 years. The main features were polyadenopathies (10 patients: 41.7%), cutaneous involvement (10 patients: 41.6%), inflammatory polyarthralgia (8 cases: 33.3%), general symptoms (6 patients: 25%), uveitis (6 cases: 25%), cholestasis (3 cases) and kidney involvement (2 cases). Lymphopenia, hypercalcemia, and hypercalciuria were observed each one in 12.5% of the cases, and high angiotensin converting enzyme (ACE) level in 38.5% of the cases. The histological proof was required in all the patients. Statistically significant associations identified were mainly hepatic involvement with general symptoms (p=0.035), peripheral lymphadenopathies (p=0.035) and kidney damage (p=0.022), and cutaneous involvement with articular manifestations (p=0.032). Systemic corticosteroids were used in half of the cases, with a good outcome in 21 cases, and recurrence in two cases. One patient was lost to follow up. The comparison to the form with mediastino-pulmonary involvement showed less lymphadenopathies (p=0.001), less lymphopenia (p=0.006), and less frequent use of corticosteroids (p=0.044).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion.<\/jats:bold>\n                    Our series was characterized by the frequency of the pure extra-thoracic form and the diversity of the systemic manifestations.\n                  <\/jats:p>","DOI":"10.2478\/rjim-2021-0012","type":"journal-article","created":{"date-parts":[[2021,4,6]],"date-time":"2021-04-06T06:08:18Z","timestamp":1617689298000},"page":"312-317","source":"Crossref","is-referenced-by-count":1,"title":["Pure extra-thoracic sarcoidosis: about 24 cases"],"prefix":"10.2478","volume":"59","author":[{"given":"Donia","family":"Chebbi","sequence":"first","affiliation":[{"name":"Department of Internal Medicine , Hedi Chaker University Hospital , Sfax , Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sameh","family":"Marzouk","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine , Hedi Chaker University Hospital , Sfax , Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mouna","family":"Snoussi","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine , Hedi Chaker University Hospital , Sfax , Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nessrine","family":"Regaieg","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine , Hedi Chaker University Hospital , Sfax , Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nawrez","family":"Gouiaa","sequence":"additional","affiliation":[{"name":"Department of Histology , Habib Bourguiba University Hospital , Sfax , Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raida","family":"Ben Salah","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine , Hedi Chaker University Hospital , Sfax , Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chifa","family":"Damak","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine , Hedi Chaker University Hospital , Sfax , Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Faten","family":"Frikha","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine , Hedi Chaker University Hospital , Sfax , Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tahia","family":"Boudawara","sequence":"additional","affiliation":[{"name":"Department of Histology , Habib Bourguiba University Hospital , Sfax , Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zouhir","family":"Bahloul","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine , Hedi Chaker University Hospital , Sfax , Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2021,8,26]]},"reference":[{"key":"2026042914164929248_j_rjim-2021-0012_ref_001","doi-asserted-by":"crossref","unstructured":"1.
