Cutaneous metastasis at a surgical drain site after gastric cancer resection

Cutaneous metastasis from intra-abdominal malignant solid tumours such as gastric adenocarcinoma is very rare. Here, we report the case of a 76-year-old male patient with a T4N2M0, poorly differentiated, signet-ring cell gastric carcinoma, who underwent potentially curative resection of the tumour and developed cutaneous metastasis at the site of the surgical drain 4 months after the operation while he was on chemotherapy. The lesion involved the skin and the subcutaneous fat only. A CT scan revealed local recurrence at the resection bed but no distant metastases. The patient died 1 month later. It is concluded that the development of cutaneous metastasis after gastric carcinoma resection indicates tumour recurrence or disseminated disease and is associated with poor prognosis.
