We describe a boy who developed a dark brown colored nodule in an area of lymphangioma circumscriptum following repeated local injuries. The nodule showed the clinical and pathologic features of solitary angiokeratoma. It is possible that previous injuries predisposed the lesion to the development of solitary angiokeratoma.
