Slow growing lesion becomes suspicious
Most of these are a uniform light brown colour and are simple solar lentigines. However when you start to see variations in the colour within a pigmented facial lesion it is time to be wary. This lesion on the ear has been developing for five years. It now has varying colours and an irregular edge. A large shave biopsy showed that it was still melanoma in situ, i.e. there was no invasive component, however it required removal of the ear lobe. A full excisional or large shave biopsy is much better than a punch biopsy in properly diagnosing these pigmented lesions.
