Abstract
|
|
|
A case of alveolar soft part sarcoma accurring in the abdominal wall in a 28 year old
woman is reported. The mass was slowly growing during past 5 years to become hen
egg sized. The lesion was suggested for a sort of malignant vascular neoplasm,
clinically, on the basis of preoperative arteriographic findings, showing highly
vascularized irregular mass fed by the right deep circumflex iliac artery with subsequent
rapid venous drainage of pooled blood.
Grossly, the mass was firm and measured 4.5×4.0×2.5㎝. The tumor was relatively
well circumscribed except for areas where it blended into surrounding skeletal muscle.
cut surface showed pinkish gray in color with multifocal hemorrhagic microcystic
appearances.
Microscopically, tumor showed organoid arrangement of lobules separated by numerous
delicate vascular septa. Individual tumor cell contained p.4.5. positive crystalline granules
in the cytoplasm and prominent nucleolus.
Brief comments on the histogenesis of this tumor, especially in relation to the
vascular smooth muscle cell are made.
