Abstract

BackgroundGastro-Intestinal stromal tumours (GISTs) are rare and our understanding of their natural history and optimal treatment are continually evolving. Port site metastasis after laparoscopy for a GIST is an extremely rare phenomenon.Case presentationWe report a case with relevant imaging and discuss factors that may have contributed to the development of this isolated metastasis.ConclusionPercutaneous methods of sampling GIST tumours for analysis should be avoided if at all possible. When necessary, prophylactic measures should be utilised to minimise the risk of seeding.

Highlights

Gastro-Intestinal stromal tumours (GISTs) are rare and our understanding of their natural history and optimal treatment are continually evolving
Computed Tomography (CT) scanning demonstrates a 13 cm multi-loculated mass adjacent to the anterior wall of the stomach radiologically suspicious for a Gastro-intestinal stromal tumour (GIST)
The advanced nature of the tumour increased the risk of a port site metastasis (PSM) but as far as we know, the port did not enter the peritoneal cavity at the site of an existing peritoneal metastasis

Summary

Introduction

Gastro-Intestinal stromal tumours (GISTs) are rare and our understanding of their natural history and optimal treatment are continually evolving. This case report of a port site metastasis following laparoscopy for a malignant GIST is, to our knowledge, only the second documented case. Computed Tomography (CT) scanning demonstrates a 13 cm multi-loculated mass adjacent to the anterior wall of the stomach radiologically suspicious for a Gastro-intestinal stromal tumour (GIST).
