Asymptomatic low-grade appendiceal mucinous neoplasm: A case report

Figure 1 Enteroscopy. A raised mass with a smooth surface measuring 3.0 cm was observed in the cecum.

Figure 2 Abdominal computed tomography. A: Markedly thickened and dilated appendix with visible cystic shadows; B: Appendix wall showed a slight enhancement following the contrast enhancement procedure.

Figure 3 Intraoperative view. A: Significantly dilated appendix; B: Linear cutter/stapler was used to laparoscopically resect the appendix and portions of the cecum.

Figure 4 Appendix. A: 12 cm in length; B: 4 cm in width.

Figure 5 Postoperative pathology. The tumor had invaded the entire appendix with mucus accumulation in the apical part of the appendix and the sub-plasma layer of the appendiceal body. The resection margins were negative (hematoxylin–eosin, × 200).
