We experienced a case of congenital arterio-venous malformation in apalmar aspect of the wrist joint region. This case rarely had symptoms and the lesion was limited in extent by angiography. We could perform total excision of this lesion for the uncommon malformation of limited extent. Postoperatively this legion has improved without recurrence. Previously published literature about congenital A-V malformation is reviewed.
