Therefore, we aimed to identify the most common causes of peripheral lymphadenopathy in hospitalized children and to determine the clinical, laboratory and ultrasound characteristics that enable fast, easy and accurate etiological diagnosis. We performed a cross-sectional study including 139 children who were hospitalized because of peripheral lymphadenopathy. Ultrasound of lymph nodes was performed in 113 (81.3%) patients. Lymphadenopathy was generalized in nine (6.5%) patients. Malignant etiology was established in only three (2.2%) patients. Bacterial lymphadenitis, infectious mononucleosis (IM) and cat scratch disease (CSD) were diagnosed in 66 (47.5%), 31 (22.3%) and 29 (20.9%) patients, respectively. Bacterial lymphadenitis was significantly associated with neutrophilia (p &lt; 0.01), and increased C-reactive protein levels (p &lt; 0.01). IM was associated with pharyngitis (p &lt; 0.01), leukocytosis without neutrophilia (p = 0.03) and increased blood liver enzyme levels (p &lt; 0.01). CSD was associated with recent contact with a cat (p &lt; 0.01), absence of a fever (p &lt; 0.01) and normal white blood cell count (p &lt; 0.01). Thorough history and clinical examination in combination with a few basic laboratory tests enable fast and accurate differentiation between the most common etiologies of lymphadenopathy in children to avoid unnecessary procedures and hospitalizations.<\/jats:p>","DOI":"10.3390\/children10101589","type":"journal-article","created":{"date-parts":[[2023,9,24]],"date-time":"2023-09-24T10:40:22Z","timestamp":1695552022000},"page":"1589","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Association between the Clinical, Laboratory and Ultrasound Characteristics and the Etiology of Peripheral Lymphadenopathy in Children"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0577-8925","authenticated-orcid":false,"given":"Vojko","family":"Berce","sequence":"first","affiliation":[{"name":"Department of Pediatrics, University Medical Centre Maribor, Ljubljanska ulica 5, 2000 Maribor, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nina","family":"Rataj","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University Medical Centre Maribor, Ljubljanska ulica 5, 2000 Maribor, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maja","family":"Dori\u010d","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University Medical Centre Maribor, Ljubljanska ulica 5, 2000 Maribor, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandra","family":"Zorko","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University Medical Centre Maribor, Ljubljanska ulica 5, 2000 Maribor, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tja\u0161a","family":"Kolari\u010d","sequence":"additional","affiliation":[{"name":"Community Health Center Velenje, Vodnikova cesta 1, 3320 Velenje, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"216","DOI":"10.1542\/pir.34.5.216","article-title":"Lymphadenopathy","volume":"34","author":"Sahai","year":"2013","journal-title":"Pediatr.
