It is predominantly observed in patients with end\u2010stage renal disease (ESRD) who are undergoing dialysis and typically presents with painful cutaneous ulcers. We report an exceptional case of gastric mucosal CUA in a dialysis\u2010dependent ESRD patient, presenting with severe upper gastrointestinal bleeding in the absence of preceding skin lesions. Histopathologic examination of gastric biopsies confirmed vascular calcification consistent with CUA. Despite medical intervention, the patient\u2019s course was complicated by poor treatment adherence and subsequent fatal outcome. This case underscores the importance of maintaining high index of suspicion for atypical, visceral presentations of CUA in high\u2010risk ESRD patients. This case was previously presented as a poster at the National Kidney Foundation 2025 Spring Clinical Meeting.<\/jats:p>\n                  <jats:p>\n                    <jats:bold>Trial Registration:<\/jats:bold>\n                    ClinicalTrials.gov identifier: NCT02278692\n                  <\/jats:p>","DOI":"10.1155\/crin\/3967671","type":"journal-article","created":{"date-parts":[[2025,12,11]],"date-time":"2025-12-11T10:55:06Z","timestamp":1765450506000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Calciphylaxis in the Upper GI Tract in an ESRD Patient: An Atypical Presentation and Review of Literature"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4969-3488","authenticated-orcid":false,"given":"Pallavi","family":"D.
