Description
Wenfeng Xu, Hao Tang, Ying Chen, and four colleagues report a four-year wrong diagnosis in this two thousand twenty-three case report. A sixty-five-year-old man carried a stomach tumor diagnosed as adenocarcinoma and received chemotherapy combined with PD-L1 immunotherapy. Doctors believed it worked, yet the tumor never shrank and his symptoms never truly improved. A repeat biopsy at the authors' hospital, checked by form, markers, and genome sequencing, gave a different answer: an epithelioid gut stromal tumor.
Epithelioid stromal tumors make up about twenty percent of these tumors and mimic poorly differentiated adenocarcinoma and lymphoma under the microscope, a known diagnostic trap. The authors draw two lessons. Tissue doctors should lean on site, form, and the right markers for this tumor family. Clinicians should judge response by symptoms and lab proof rather than trusting a tissue label too far.
