Cutaneous Metastases from Gastric Cancer Following a Multimodal Radical Therapeutic Approach: A Case Report and Literature Review

Cutaneous metastases from gastric adenocarcinoma represent a rare and aggressive manifestation, particularly when they occur after radical treatment. This article presents an exceptional case of a 48-year-old man who developed multiple cutaneous metastases just four months after a subtotal gastrectomy and adjuvant chemotherapy for gastric adenocarcinoma. This cutaneous metastatic dissemination, indicative of a particularly aggressive nature, led to the initiation of first-line treatment with trastuzumab and FOLFOX. This case highlights the necessity of heightened vigilance for atypical skin lesions in patients with a history of gastric cancer and underscores the therapeutic challenges associated with this unusual complication.
