Abstract
A case of gastric cancer metastasized to the breast and skin in a 37-year-old female is reported.
Two months after total gastrectomy for a poorly differentiated adenocarcinoma of the stomach, a subcutaneous nodule appeared on the left anterior chest wall. Multiple nodules appeared on the anterior chest wall including the right breast and abdominal wall, successively. Though total mastectomy was carried out because of marked enlargement of the right breast mass, she died four weeks after the operation. The histological examination of the resected mass revealed metastasis of the gastric cancer.
From the findings that no metastatic lesion was detected in the liver nor the lung, multiple lymph nodes were swollen around the abdominal aorta, cancer cells were observed in the lymphatic vessel of the resected breast, and skin metastasis appeared only on the anterior chest and abdominal wall, lymphatic metastatic route was speculated in this case.
As the metastases to the breast and skin are the extensive progress of the gastric cancer, chemotherapy should be selected firstly, and then a plan of the later treatment should be decided in consideration of the effect of the chemotherapy.
