Mohs micrographic surgery is a reliable outpatient surgical method of removing skin cancer. The method includes tissue excision in thin layers, colour-coding of excised specimens, accurate orientation of excised tissue through construction of tissue maps, and microscopic examination of horizontal frozen sections. Selected basal and squamous cell carcinomas are treated most commonly by this method, however, a variety of less common tumors are also amenable to treatment. Mobs micrographic surgery offers the highest cure rates for selected malignancies while maintaining maximal preservation of normal tissue and important anatomic structures.
