Incidental gastric signet-ring cell carcinoma metastasis to the skin in basal cell carcinoma.

The skin is an unusual location for métastases from visceral carcinoma, and cutaneous métastases from gastric carcinoma are rare. Cutaneous métastases display various clinical features, but usually occur as non-specific firm nodules. However, no cases of occult métastases from gastric carcinoma have been reported. We describe here a patient with clinically unapparent cutaneous metastasis fi^om gastric signet-ring cell carcinoma that was diagnosed as an incidental finding in an excision performed for unrelated basal cell carcinoma (BCC) of the upper eyelid.
