Cutaneous ulcerations of the scalp are infrequent and pose a diagnostic challenge. Infectious origins, malignant diseases, vasculitides, neutrophilic dermatoses, and trigeminal trophic syndromes should be considered.1 This report describes a patient with alopecia and an ulcer in the occipital region of the scalp, which developed following atlanto-axial fixation surgery of the cervical spine resulting in C2 nerve dysfunction. Cutaneous complications of atlanto-axial fixation surgery have been so far underreported in the dermatological and the orthopedic literature.1-3
