What is a primary cause of hyperplasia/pseudoverrucous lesions?

• A. Chronic irritation and prolonged skin exposure to urine and moisture
• B. Usually from too large of an opening cut in skin plate with high liquid output stomas
• C. Bacterial infection
• D. Allergic reaction to adhesives

Answer: (A)

Chronic irritation from moisture exposure is the primary driver of hyperplasia and pseudoverrucous lesions. When urine or other effluent continually sits on the peristomal skin, the area becomes macerated and inflamed. In response, the skin undergoes epithelial thickening and proliferation, producing raised, wartlike or plaque-like papules—these are the pseudoverrucous lesions. This pattern is a reaction to ongoing irritant contact, not primarily an infection or an allergy. Leaking or poorly fitting appliances that allow continuous moisture to reach the skin increase the risk, since they sustain the irritant exposure. While bacterial infection or an allergic contact dermatitis can irritate the skin, they don’t explain the characteristic proliferative, wartlike lesions caused by long-term irritation. Preventing and treating these lesions focuses on stopping the moisture exposure—improving the appliance seal, managing output, and protecting or barriering the skin—and addressing any infection or allergy if present.
