History:

 This lesion was noted on the ear during a routine skin check. Patient was not aware of it. The dermatoscopy showed an irregular blue black structureless lesion with some peripheral grey dots as peppering, an excentric area of regression and some white clods.

The histology was reported as an in situ melanoma with some dermal regression. It was excised with 5 mm clinical margins after the initial narrow excision biopsy.
