Key result
A retained gauze sponge left behind during a nephrectomy 38 years earlier resulted in the development of an epitheloid angiosarcoma of the splenic capsula.
Case Report (n=1)
This case report provides evidence supporting the concept of inert foreign body tumorigenesis following a retained surgical sponge.
Retained sponges may rarely cause delayed angiosarcoma; leaves open generalizability of foreign-body tumorigenesis.
A case of an epitheloid angiosarcoma of the splenic capsula is reported. This tumour developed in close relation to a gauze sponge, which was accidentally left behind 38 years earlier during a left-sided nephrectomy. The tumour probably arose from pluripotential mesothelial stem cells within the splenic capsula, with subsequent mesothelial to endothelial metaplasia and neoplastic transformation. Clinical, radiological, peroperative and pathological features of this angiosarcoma add to the validity of the concept of inert foreign body tumorigenesis.

Keymeulen et al. (2004) conducted a case report in Epitheloid angiosarcoma of the splenic capsula (n=1). Retained gauze sponge (foreign body) was evaluated on Development of epitheloid angiosarcoma. A retained gauze sponge left behind during a nephrectomy 38 years earlier resulted in the development of an epitheloid angiosarcoma of the splenic capsula.
