A Case of Mohs Micrographic Surgery for Facial Porocarcinoma in an Adolescent and Literature Review

Introduction Eccrine porocarcinoma (EPC), the most common malignant tumor of the eccrine sweat glands, accounts for approximately 0.005%–0.01% of all skin malignancies. However, a standard treatment for EPC is currently lacking. Many previous studies demonstrated that it mainly occurs in the elderly and is extremely rare in adolescents. Here, we report a case of Mohs micrographic surgery for facial porocarcinoma in an adolescent patient. Case A 19‐year‐old male adolescent was admitted to the hospital with a 6‐month history of a gradually enlarging itchy brown mass in the right nasolabial sulcus. After a pathological examination of the skin biopsy in the outpatient department, he was admitted to the hospital for Mohs surgery. Postoperatively, the wound defect was repaired using a local flap. Results The patient recovered well after the surgery, and no recurrence was observed after 35 months of follow‐up. Conclusion Our case demonstrated the effective early diagnosis and surgical intervention of EPC.
