title: Intravascular angiomatosis in female urethral mass. Masson intravascular hemangioendothelioma.
abstract: A case of Masson intravascular hemangioendothelioma hitherto undescribed in the female urethra is reported. The condition has bizarre histopathologic appearances which sometimes pose a problem in differentiating it from angiosarcoma. Recognition of the condition, particularly in a female urethra which is not an infrequent site of vascular lesions such as caruncles and varices, is therefore emphasized to avoid unnecessary drastic treatment.
