Facial lesions represent a large proportion of consultations to the dermatologist and the otolaryngologist. Fortunately, most of these lesions are found in typical locations, have typical morphological features, or both. Those that do present atypically can cause frustration for both patient and physician. The potential for misdiagnosis can then lead to unnecessary procedures and suffering. We report an unusual presentation of a cutaneous odontogenic sinus in a patient who underwent several surgical procedures before the accurate diagnosis was made. This case serves as a reminder to all physicians to continually reassess atypical lesions when conservative, and more drastic, treatment protocols fail.
