A dusky blue mark, but not a bruise
THIS has not resolved like a bruise over the past two months and two others have appeared medially to it. The white area is a graft donor site to close a melanoma excision site lower down on this leg.
The grey-blue lesions are in-transit melanoma metastases. Histologically they looked like blue naevi but review confirmed their true nature. When a patient has had a melanoma, any blue naevus-like lesion should be viewed with concern. Dermatoscopically melanoma metastases can look very similar to blue naevi.
Always biopsy these
