Scrotal wall metastasis as the first manifestation of primary gastric adenocarcinoma.

Metastases to the scrotal wall are very rare, and being the initial manifestation of occult primary tumours is even rarer. We report on a patient presenting with painless scrotal swelling, attributed to a solid extra-testicular mass found on ultrasonography. Subsequent investigations and surgical exploration revealed it to be a scrotal wall metastasis from an occult gastric primary. To our knowledge, this is the first report of a scrotal wall metastasis from gastric adenocarcinoma. The ensuing discussion and literature review highlight the diagnostic challenges posed by an extra-testicular scrotal metastasis from an occult primary tumour.
