Perigastric Lymph Node Metastasis from Papillary Thyroid Carcinoma in a Patient with Early Gastric Cancer: The First Case Report

다국어 초록 (Multilingual Abstract)

Distant metastasis from papillary thyroid carcinoma (PTC), particularly from papillary thyroid microcarcinoma, is rare. We present a caseof perigastric lymph node metastasis from PTC in a patient with early gastric cancer and breast cancer. During post-surgical follow-upfor breast cancer, a 56-year-old woman was diagnosed incidentally with early gastric cancer and synchronous left thyroid cancer. Therefore,laparoscopic distal gastrectomy with lymph node dissection and left thyroidectomy were performed. On the basis of the pathologicfindings of the surgical specimens, the patient was diagnosed to have papillary thyroid microcarcinoma with perigastric lymph nodemetastasis and early gastric cancer with mucosal invasion. Finally, on the basis of immunohistochemical staining with galectin-3, thediagnosis of perigastric lymph node metastasis from PTC was made. When a patient has multiple primary malignancies with lymphnode metastasis, careful pathologic examination of the surgical specimen is necessary; immunohistochemical staining may be helpful indetermining the primary origin of lymph node metastasis.
