Atypical "Rodent Ulcer" Basal Cell Carcinoma

These lesions are moist ulcers which may not have the characteristic rolled, translucent border of a nodular Rodent Ulcer or Basal Cell Carcinoma BCC. Often, they are much larger than the pre-auricular lesion seen here, and represent neglected lesions.

The typical basal cell carcinoma appears as a small, pearly, dome-shaped nodule with small visible blood vessels (telangiectasias).
