A 33-year-old woman with fever and abdominal distension was admitted to our hospital. An enhanced computed tomography scan showed intraperitoneal abscess in the lower abdomen. We wanted to perform percutaneous drainage but because there was a risk of intestinal damage, we first administered antibiotic therapy. A diagnosis of appendiceal carcinoma was obtained by colonoscope, and ileoceal resection and D3 lymph node dissection were performed. The patient was under 50 years of age, so we performed the test of microsatellite instability (MSI), which microsatellite stable (MSS), so this case had no relationship with Lynch syndrome. The lymph node examination indicated metastasis, so we treated her with postoperative adjuvant chemotherapy. She has remained in good health, without clinical evidence of recurrent disease for 3 months after the operation. The young - onset appendiceal carcinoma is comparatively rare, and we discuss this case in connection with the published literature.
