1.  Parotid Gland Metastasis of Breast Cancer: Case Report and Review of the Literature 
Breast Care  2011;6(6):471-473.
Parotid gland metastasis in breast cancer is extremely rare, and only 14 cases have been reported between 1982 and 2010.
Case Report
A 67-year-old female patient was diagnosed with invasive lobular carcinoma of the left breast. Although clinical staging was T1N3M1 (stage IV), the tumor experienced a complete response to chemotherapy. We therefore performed a mastectomy followed by radiotherapy, and continued administration of trastuzumab. However, 11 months later, the patient complained of a swelling in the left parotid gland. Histology following a partial parotidectomy revealed a parotid gland metastasis from the breast.
Treatment with capecitabine in addition to trastuzumab, which is one of the strategies applied in HER2-positive breast cancer, was effective in our patient. Analysis of the 14 cases of parotid gland metastasis from the breast reported between 1982 and 2010 revealed that the metastasis may occur not by direct lymphatic but by hematogenous spread.

2.  Granular cell tumor of the common bile duct: A Japanese case 
Granular cell tumor (GCT) of the biliary system is rare. It is reported that it occurs more commonly in young black women. We report here our seldom experience of a Japanese case in whom icterus was found as a first symptom just after a caesarean operation. A 36-year-old Japanese woman developed icterus after delivery by the Caesarean operation. A surgical operation was performed without can deny that there was a tumor-related change in a bile duct as a result of examination for various images. As a result of pathological evaluation, GCT was diagnosed. By the preoperative organization biomicroscopy result, it was not able to be attachd a right diagnosis. It was thought that this tumor, although rare, should be considered as one of the causes of biliary stenosis in the younger population.
