Another elderly gentleman with an "ugly duckling" lesion on the right shoulder. The pattern at 10 o'clock is reticular ( an important comment because the new lesion has arisen in a solar lentigo and this narrows down the Dx ). The rest of the lesion has no specific pattern so it is termed chaotic. The important area to look at is between 6 and 7 o'clock where there is grey pigment ( ie in the dermis) and means that a Melanoma has to be included in the differential diagnosis.

This lesion is on the arm of an elderly lady. It appeared two weeks ago and grew rapidly. It has a central keratin plug and the blood vessels are spiral and looped in response the stretching effect the rapid growth has on them. This is most likely to be a Keratoacanthoma. The differential diagnosis is with an SCC. A diagnosis is important so the options are to remove completely or to shave the top for histology and curette and cauterize the base. Histology - Unable to differentiate between a Keratoacanthoma and a Squamous Cell Carcinoma - this type of report is common for these lesions and means that if it has not been removed completely , it needs to be watched very closely.
