Angiosarcoma with Synchronous Cutaneous and Small Bowel Involvement: A Report of a Rare Presentation.

ABSTRACT

Angiosarcomas are mesenchymal neoplasms of vascular origin that represent approximately 2% of soft tissue sarcomas. We discuss the case of a 75-year-old female who had presented with a purple nodular rash along the bilateral nasolabial folds. Upon further work-up, she was diagnosed with angiosarcoma, with the confirmed involvement of multi-focal sites. These included biopsy proven sites of the face and duodenum along with the radiographic involvement of the lungs, liver, and osseous tissue. We report this unique presentation of a rare malignancy and the treatment course with radiation, paclitaxel, and bevacizumab. We also discuss the implications of her co-morbid liver cirrhosis and gastric antral vascular ectasia (GAVE) in terms of its influence on the development of the angiosarcoma and treatment response.
