A Case of Pyoderma Gangrenosum with Rectal Polyp



Abstract
Since the classical description of pyoderma gangrenosum by O¢¥Leary, Brunsting and GoecXerman in 1930, a considerable number of reports of this clinical entity has appeared.
Pyoderma gangrenosum is a painful, ulcerative disease of the skin. The ulcers are highly characteristic in clinical feature as necrotic pus covered lesions having purple colored and elevated border with red halo. Frequently, the ulcers heal with a cribriform type of scar.
Its pathogenesis is not understood clearly.
We present a case of pyoderma gangrenosum developed on the leg in a 11-year old boy occurring with rectal polyp, the association of which is very rare in world wide. And this case has the evidence of cell mediated immunity impairment characterized by no response to mumps antigen and purified protein derivatives, and not to be activively sensitized by DNCB.
