Abstract
Skin and soft tissue lesion removal contributes significantly to both academic and private plastic surgery practices. When encountering various types of dermatologic diseases, it is crucial for a plastic surgeon to exercise caution and consider further medical evaluation before proceeding with local excision of any abnormal skin growth, especially those that involve the face in the pediatric or adolescent population. In this case report, we discuss the case of a child who presented with a primary cutaneous skin lesion involving the left nasal ala, which was ultimately diagnosed as B-cell acute lymphoblastic leukemia. This case is reported to highlight B-cell acute lymphoblastic leukemia for plastic and reconstructive surgeons so that it can be included in the differential when encountering fast growing cutaneous lesions of the face in children.
