Crypt abscess	Aggregates of neutrophils, fibrin, and sloughed epithelial cells within a partially ruptured colonic gland
Erosion	The superficial destruction of a surface by stimuli such as inflammation
Hyperplasia	Abnormal increase in the volume of a tissue or organ caused by the formation and growth of new normal cells
Infiltration	The pathological accumulation of immune cells in tissue
Scoring system	0, no lesion; 1, mild; 2, moderate; 3, strong
