Rectal biopsy was taken with the impression of ulcerative colitis r/o IBD with the recommendation of fluid and electrolyte and antibiotics with follow histology and laboratory tests for differential diagnosis and treatment (Figure 1).

Note: Due to the loss of elastic tension and to formalin shrinkage, the measurements in the gross description may be less than those taken at the time of surgical removal (Figures 2 and 3).
