Radiation proctitis - Chronic
•
Repopulation of the mucosal
cells occurs in the later stage of
the acute phase
•
The severity of the damage to
supportive connective tissue
limits the degree of

•
Fibrosis of the underlying
connective tissue causes
patchy ischemia of the mucosa,
which may cause ulceration
•
Local trauma or infection
often precipitates these ulcers
