Abstract
A 74-year-old man had sustained a penetrating lead pencil injury to his right lower leg at the age of fifteen. A dark gray macule occurred that remained unchanged for fifty-eight years. An enlarging black nodule appeared in this area, simulating a melanoma, when the patient was seventy-three years old. Histologic examination revealed exogenous pigment and a foreign body reaction.Entities:
