The most common metastatic sites of
gastric cancer are
liver,
lung,
bone and
adrenal gland. However,
skin metastases from
gastric cancer are relatively rare. We herein
report a case of advanced
gastric cancer with perianal
skin metastasis in a 70-year-old
male. On
admission, patient presented with epigastric
pain.
Endoscopy and abdominal CT scan demonstrated the stage IV
gastric cancer. He had one painless nodule on perianal
skin area,
biopsy of that lesion showed a feature of poorly differentiated
adenocarcinoma clinically from the
stomach. We suspected that the perianal lesion was originated from
gastric cancer.
