Answer

The fissure is not usually excised; therefore, no pathology specimen is available for examination. When it is excised, the tissue typically exhibits nonspecific inflammation. If some of the muscle is accidentally excised with the fissure, the internal sphincter usually demonstrates fibrosis.
