Invasive melanoma in the donor and recipient sites of a Hutchinson's freckle transplanted in a split skin graft.
An extraordinary case of synchronous development of invasive melanoma in the donor and recipient sites of a split skin graft is reported. The histological features suggest transplantation of a Hutchinson's melanotic freckle (lentigo maligna) at operation 10 years previously as the probable cause. The case is particularly interesting in that the invasive melanoma at both sites was at a similar stage despite a considerable difference in exposure to sunlight in the long postoperative period, perhaps discounting this factor as a precipitating cause of melanoma in Hutchinson's melanotic freckle (lentigo maligna melanoma).
