metastasis from a malignant tumor to the palatine tonsils is rare, accounting for only 0.8% of all tonsillar tumors, with only 100 cases reported in the english-language literature. various malignant lung carcinomas may metastasize to the tonsils. a few cases of tonsillar metastasis from neuroendocrine lung carcinoma have been reported. a 67-year-old female underwent a right tonsillectomy becau...

OBJECTIVES To investigate the role of functional visceral fat activity assessed by preoperative F-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in colorectal cancer (CRC) for predicting regional lymph node (LN) or distant metastasis. METHOD We evaluated 131 patients with newly diagnosed CRC. They all underwent pre-operative 18F-FDG PET/CT and surgery....

background: phyllodes tumors are uncommon neoplasms of the breast. data about their outcome is limited. this study aims to evaluate patients diagnosed with phyllodes tumors in terms of local recurrence, distant metastasis and overall survival. methods: we retrospectively reviewed the medical records of 129 women with phyllodes tumors who referred to our center from 1999 to 2013. clinical and pa...

BACKGROUND The correlation between primary tumor volume and nasopharyngeal carcinoma (NPC) UICC 2002 T classification, N classification and distant metastasis after radiation therapy was discussed to provide further evidence for the inclusion of tumor volume into the TNM classification staging system. METHODS Between February 2001 and December 2008, 666 patients with NPC treated with intensit...

Distant metastasis is the most important prognostic factor in nasopharyngeal carcinoma (Zhang et al., 1989; Tang et al., 2010; Pan et al., 2012; Peng et al., 2013). Generally, 30% patients with NPC will eventually develop distant metastasis, but only one-sixth patients with metastasis are diagnosed at their initial diagnosis, and another one-third are identified within 3 months after diagnosis ...

BACKGROUND This study identified sex differences in progression of cutaneous melanoma. METHODOLOGY/PRINCIPAL FINDINGS Of 7,338 patients who were diagnosed as an invasive primary CM without clinically detectable metastases from 1976 to 2008 at the University of Tuebingen in Germany, 1,078 developed subsequent metastases during follow up. The metastatic pathways were defined in these patients a...

Gastrointestinal (GI) tract metastasis of primary breast cancer is very rare. We present a patient with small bowel obstruction from distant metastasis of primary breast cancer. Each characteristic features of concern of GI tract distant metastasis from many pervious studies has been reported differently. We should remember that GI tract metastasis may coexist when patients with breast cancer h...
