MMS: Mohs micrographic surgery INTRODUCTION The overall infection rate after Mohs micrographic surgery (MMS) is low, with 1 study estimating it to be 3.2% for sutured wounds and 6.8% for second intention wounds. Risk factors for infection after MMS include malnutrition, older age, diabetes, immunosuppression, and extensive inflammatory skin disease. Surgical sites on the ears, lower extremities, and lips are considered high-risk sites for postoperative surgical site infections. In a study of positive culture findings following MMS, infections were most commonly caused by Staphylococcus aureus (45.4%) and Pseudomonas aeruginosa (10.8%), along with other gram-positive and gram-negative species. To our knowledge, no cases of delayed infections of the ear have been reported following MMS. Herein, we present 2 such cases of delayed ([30 days) P aeruginosa infections after MMS on the ear.
