Abstract

Even if grade 1 neuroendocrine tumors (NET) have low malignant potential, they may still be associated with lymph node metastasis. While the World Health Organization (WHO) classification requires determination of the grade of malignancy and presence of metastasis, it is also useful to evaluate tumor diameter, extent of invasion, and histological characteristics(cell variant, nuclear atypia, and ductal invasion). The authors present 2 cases of rectal NET excised by laparoscopic surgery. Considerations for surgical indications in rectal NET are made based on these case reports.
