This case report presents a 30-year-old Palestinian woman with NF1 who experienced severe abdominal pain and melena, leading to the diagnosis of a jejunal GIST, which was surgically removed. Postoperative imaging revealed cervical and thoracic lesions. A follow-up PET scan indicated hypermetabolic masses in the thyroid and chest. Subsequent surgery confirmed the diagnosis of PTC and neurofibromas, with whole exome sequencing identifying a likely pathogenic variant in the NF1 gene. This case demonstrates the value of comprehensive evaluation and genetic counseling for NF1 patients due to the risk of multiple tumors, which points to careful monitoring for early detection and management. To our knowledge, this instance is the first reported case of concurrent GIST and PTC in a patient with NF1.<\/jats:p>","DOI":"10.3389\/fonc.2025.1529765","type":"journal-article","created":{"date-parts":[[2025,7,10]],"date-time":"2025-07-10T05:31:38Z","timestamp":1752125498000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case
