Intravascular endothelial hyperplasia, or Masson’s tumor, is a benign vascular lesion with no well-defined pathogenesis. The response to vascular damage is believed to be one of the main reasons for its development. It is a typically painless injury, solitary, with slow evolution. This report aims to describe a case of Masson’s tumor in an unusual place, the hallux nail matrix, and discuss its main characteristics.
