To present a case of primary malignant mesothelioma originating from the greater omentum in a patient without asbestos exposure and discuss diagnostic complexities.
Observed a 71-year-old male with recurrent diarrhea, abdominal distension, and weight loss.
Conducted abdominal contrast-enhanced CT, revealing 'cake-like' thickening of the omentum and massive peritoneal effusion.
Performed laparoscopic palliative tumor resection and drainage of peritoneal effusion.
Postoperative pathology and immunohistochemistry confirmed diagnosis of epithelioid mesothelioma.
Administered anti-infective therapy, nutritional support, and anti-tumor treatment with stable disease control at follow-up.
Patient diagnosed with epithelioid mesothelioma based on immunohistochemistry findings.
Stable disease control achieved at three-month follow-up after individualized treatment.
Highlighting the importance of recognizing symptoms as potential indicators of rare mesothelioma.
