VERMIFORM APPENDIX, APPENDECTOMY: | |||
- APPENDIX WITH LYMPHOID HYPERPLASIA AND FOCAL MUCOSAL EROSIONS. | |||

===Micro=== | |||
The sections show appendiceal wall with focal mucosa erosions and several intraluminal | |||
neutrophil clusters. Lymphoid hyperplasia is present. Fecal material is present within | |||
the lumen of the appendix. | |||
There are no neutrophils within the muscularis propria. There is no serositis. There is | |||
no distortion of the crypt architecture. No granulomas are identified. No cryptitis is | |||
identified. | |||
====Alternate==== | |||
The section show appendiceal wall without increased numbers of neutrophils. The | |||
appendiceal lumen has cellular debris and inflammatory cells. The mucosa has prominent lymphoid tissue | |||
with germinal centre formation. | |||
No intraluminal pathologic micro-organisms are seen. There is no serositis. There is no | |||
distortion of the crypt architecture. No granulomas are identified. No cryptitis | |||
is identified. | |||
