Core Tip	Cancer of unknown primary (CUP) is a metastatic cancer whose origin site remains undetermined after comprehensive examinations. Abdominal lymph node metastasis, a common clinical manifestation of CUP, is prone to diagnostic errors because the tissue of origin is often incompletely identified. We report a case where the initial diagnosis was early gastric cancer with abdominal lymph node metastasis. After relevant re-examination, the metastatic lymph nodes were determined to originate from prostate cancer. This emphasizes the importance of diagnostic awareness of suspicious metastatic lesions and the significance of multidisciplinary diagnosis and treatment.
