Alkaline encrustations are often associated with which of the following?

• A. Pseudoverrucous lesions, alkaline urine, or concentrated urine that pools
• B. Hypersensitive reaction to adhesives
• C. Low urine output
• D. High moisture skin

Answer: (A)

Alkaline encrustations happen when skin is in prolonged contact with urine that is both alkaline and concentrated, especially if urine pools under the ostomy appliance. The high pH drives mineral salts to precipitate on the skin, forming crusty encrustations. Chronic exposure also often leads to pseudovercous lesions, which are raised, irritated skin changes from ongoing urine irritation. So the strongest, most direct association is with pseudovercous lesions and alkaline or concentrated urine that pools. The other factors describe different skin issues but don’t explain the mineral crusting pattern seen with this condition.
