We present a case of primary diaphragmatic IPT-like FDCS in a woman in her 70s who was incidentally found to have a subdiaphragmatic mass during routine follow-up. Preoperative imaging suggested a hepatic tumor. However, laparoscopic exploration revealed that the lesion originated from the diaphragm. The tumour was completely resected with partial diaphragmatic excision, followed by primary closure. Histopathological examination demonstrated characteristic inflammatory features, and in situ hybridization revealed Epstein\u2013Barr virus\u2013encoded RNA, confirming the diagnosis of IPT-like FDCS. The patient had an uncomplicated postoperative recovery and remained free of disease recurrence at 30\u00a0months after surgery. This case underscores the need to include diaphragmatic tumors when evaluating atypical hepatic dome lesions that lack the characteristic imaging features of hepatic malignancy.<\/jats:p>","DOI":"10.1093\/jscr\/rjag167","type":"journal-article","created":{"date-parts":[[2026,3,21]],"date-time":"2026-03-21T16:35:18Z","timestamp":1774110918000},"source":"Crossref","is-referenced-by-count":0,"title":["Primary
