Abstract
|
|
|
Primary angiosarcoma of the greater omentum is extremely rare. We present a case of angiosarcoma arising from the greater omentum in a 56-year-old-woman. She was admitted due to abdominal mass that had found 20 days prior. Abdominal CT scan
showed
an
ill-defined lobulated, well enhanced mass in the right lower abdomen. An omentectomy including the tumor was performed.
Histopathological examination showed the excised tumor to be an angiosarcoma. Immunohistochemical studies were strongly positive for vimentin, Factor VIII-relative antigen, and CD34 staining, but were negative for CD68, S-100 protein, and
cytokeratin
staining. The clinical presentation, course and treatment of the patient are discussed.
