[Keratoacanthoma over the donor site of a laminar skin graft].
We present a case of keratoacanthoma type II in a 38-year-old female patient, which developed in the thigh over the donor site of a laminar skin graft, six weeks after the procedure. The graft was utilized to cover the defect secondary to the resection of a melanoma. The possible role played by mechanical trauma in the development of this tumor, rare under such circumstances, is discussed. Similar previously published cases are reviewed.
