Hemangiosarcoma subsequent to radiotherapy for a hemangioma in infancy.
A case is presented of a 31-year-old white man who developed a hemangiosarcoma in the very place where 30 years ago a hemangioma had been treated by radiotherapy. The rarity of such an occurrence is attested to by the fact that only two similar cases were found in the English medical literature.
