title: Cotyledonoid hydropic intravenous leiomyomatosis: a new variant leiomyoma.
abstract: OBJECTIVE
  We present the histopathological findings of a series of six cases of a benign uterine smooth muscle tumour with an unusual growth pattern.
  
  
  RESULTS
  All cases have the appearances of the recently described dissecting (cotyledonoid) leiomyoma. In addition, three of these lesions demonstrate the features of intravenous leiomyomatosis with varying degrees of hydropic degeneration.
  
  
  CONCLUSIONS
  This combination of phenotypes has not previously been described within the literature; therefore we propose that these are classified as examples of 'cotyledonoid hydropic intravenous leiomyomatosis', a new variant of unconventional leiomyoma.
