Imiquimod-Associated Localized Skin Ulceration in a Patient With Uncontrolled Diabetes

BACKGROUND: Human papillomavirus, one of the most common viral infections worldwide, frequently manifests as condyloma acuminata, or anogenital warts. First-line treatment of this condition includes the use of imiquimod, a topical immunomodulator. CASE: We describe a case of a localized skin ulceration necessitating surgical debridement after the use of topical imiquimod for 24 hours in a patient with uncontrolled type 2 diabetes mellitus. After debridement, the patient's wound healed appropriately, with regular wound clinic visits and diabetes education. CONCLUSION: Health care professionals should use caution when prescribing imiquimod in patients with uncontrolled type 2 diabetes mellitus.
