Abstract:
Cutaneous metastasis of colorectal cancer is uncommon. Therefore, in this case study, we present a unique case of cutaneous metastasis of signet ring adenocarcinoma. The patient presented with generalized asymptomatic subcutaneous nodules 2 years after primary tumor diagnosis. Skin metastasis appeared 3 months before the liver and lung metastasis. However, the patient died 4 months later. Therefore, clinicians should observe signs of distant metastasis of colorectal cancer to enhance survival and improve outcomes.
