Description: Close up

History:

 This lesion was noted during a routine skin examination in a patient with a past history of melanoma. The coiled vessels suggested it might be an area of Bowen's disease. I was concerned it might be an amelanotic melanoma but the latter usually has polymorphic vessels.

The histology showed a mildly irritated seborrhoeic keratosis.
