Most patients (69%) had multifocal disease. In addition to classic risk factors such as oral contraceptive use and obesity, 35% had a history of neoplasm and 15% had glycogen storage disease. Next\u2010generation sequencing was performed on 13 HCAs; germline testing was available in 1 patient with familial adenomatous polyposis. While molecular testing had limited impact on reclassification, it was valuable in cases with ambiguous IHC profiles and in guiding management of patients with atypical or syndromic presentations by excluding variants associated with malignant potential.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Paediatric HCAs arise in diverse clinical contexts and may require individualized treatment planning.
