Which statement best describes the appearance of peristomal PG ulcers?

• A. Ulcers are full-thickness, circular, well-defined with red to purplish margins and may be undermining
• B. Ulcers are shallow and heal quickly
• C. They do not exude any fluid
• D. They are only found on intact skin

Answer: (A)

Peristomal pyoderma gangrenosum ulcers around a stoma are deep, full-thickness lesions with distinctive violaceous, undermined margins. They often appear circular or round around the stoma and have red to purplish borders as the necrotic tissue and inflammatory response create a violaceous rim. These ulcers tend to enlarge quickly and may exude fluid, reflecting their inflammatory and destructive nature. They are not shallow, they don’t heal rapidly, and they occur on peristomal skin rather than on intact skin. This combination of depth, shape around the stoma, and violaceous undermined margins is the hallmark described, making that option the best fit.
