Basal cell carcinoma of the nose = The anatomic distribution of these tumours is depicted in Figure 3. The most frequent location for these malignancies was the nasal ala (31.5%). The next most common area was the nasal tip (26.6%) followed by the lateral nose (20.7%), dorsum (10.8%) and alar groove (9.8%). Skin tumours occurred infrequently at the nasal root (0.3%) and columella (0.3%).
