Lymphoid aggregate polyp.

Our binary approach (serrated vs adenoma) and surveillance model means that any polyp, including normal and lymphoid aggregates proximal to the sigmoid will be categorized as an SRL (serrated vs. adenoma) by our CNN. This strategy therefore biases toward OP-shortened surveillance intervals and discordance with TP.Lymphoid hyperplasia. Lymphoid hyperplasia is an increase in the number of normal cells contained in the lymph nodes. These cells are called lymphocytes.
