It is well known that up to 2% of chronic @entity75 can transform into @entity5 . Most of them are @entity957 ( @entity957 ) and, more occasionally, @entity1491 ( @entity1491 ). The incidence of @entity320 ( @entity320 ) is extremely low. To the best of our knowledge, there are only 23 such cases reported in the literature. We report here three cases of @entity320 arising on burn scars and analyze the 23 cases reported previously. Case 1: a 74-year-old Japanese @entity1 sustained a @entity130 on about 54% of his whole body surface when he was accidentally bathed in boiling oil at the age of 37 years old. Some small @entity5 developed on the burn scar on his right lumbar region. A wide excision of the @entity5 was performed. Case 2: a 51-year-old Japanese @entity1 was injured on her right forearm and face by deep burns from a flame when she was 7 months old. She presented with a rapidly growing, painless black nodule on the dark @entity272 on her right forearm. She was treated with a wide excision followed by a full-thickness skin graft. Intravenous administration of one unit of @entity1012 every week has been continued. Case 3: a 73-year-old Japanese @entity1 was burned on her left leg and hand from a flame when she was 6 years old. A nodular lesion appeared within the @entity1066 two months previously and it was growing rapidly. This lesion was ulcerated on the top of its central area and was slightly reddish without any @entity2118 . The @entity1 was treated with a wide excision and a split-thickness skin graft. The 5-year survival rate of @entity320 in an old burn scar is 53.6%. It is suggested that the prognosis of @entity189 is not worse than that of @entity189 .
