Multiple Rectal Ulcers (88 of 110)
Case description
Pseudopolyposis is probably the most common local
complication of ulcerative colitis. The reported incidence
varies from 12,5% to 74%, depending on the diagnostic
criteria employed and patients groups studied.
Pseudopolyps represent polypoid edematous mucosal tags,
regenerative mucosal islands between areas of ulceration
or heaped-up granulation tissue covered by glandular
epithelium (Dukes, 1954) They may be seen in the active
or quiescent phase of the disease and can be diffuse or
local in distribution. There is a direct relation between
severity and extension of the disease and the incidence of
pseudopolyposis, although the outcome of severe attacks
of ulcerative colitis in the presence of pseudopolyps has
been found to be more favourable.
