[Breast Cancer Metastasis to the Mesentery Diagnosed Via Laparoscopic Biopsy-A Case Report].

Breast cancer can metastasize to organs all over the body, but isolated mesenteric metastases are rare. A 72-year-old female, with a history of invasive lobular carcinoma of the breast treated with breast-conserving therapy and axillary lymphadenectomy 7 years previously and 5 years of endocrine therapy, presented with asymptomatic elevated serum carcino- embryonic antigen. Computed tomography(CT)revealed no obvious distant metastasis, but showed increased adipose tissue density around the pancreas suggestive of acute pancreatitis.

A 73-year-old man presented with anemia, and gastroscopy showed a nonpigmented tumor in the esophagogastric junction. The result of the tumor biopsy initially suspected poorly differentiated adenocarcinoma. However, additional immunohistochemical examination revealed malignant melanoma.
