Although recent studies suggest that high intakes of meat and heme iron are risk factors for several types of cancer, studies in relation to esophageal adenocarcinoma (EAC) are scarce. Previous results in the European Prospective Investigation into Cancer and Nutrition (EPIC) based on a relatively small number of cases suggested a positive association between processed meat and EAC. In this study, we investigate the association between intake of different types of meats and heme iron intake and EAC risk in a larger number of cases from EPIC. The study included 481,419 individuals and 137 incident cases of EAC that occurred during an average of 11 years of follow-up. Dietary intake of meat (unprocessed/processed red and white meat) was assessed by validated center-specific questionnaires. Heme iron was calculated as a type-specific percentage of the total iron content in meat. After adjusting for relevant confounders, we observed a statistically significant positive association of EAC risk with heme iron and processed meat intake, with HR: 1.67, 95% CI: 1.05-2.68 and HR: 2.27, 95% CI:1.33-3.89, respectively, for comparison of the highest vs. lowest tertile of intake. Our results suggest a potential association between higher intakes of processed meat and heme iron and risk of EAC.

Serous cystadenomas of the pancreas have been classified as benign exocrine tumors. There have been rare cases of malignant behavior, and in exceptional cases, coexisting neoplasms have been reported. We report a case of a coexistent neuroendocrine tumor identified within a serous cystadenoma in a 78-year-old woman, which was discovered incidentally after complete resection of the tumor. Given the unpredictable metastatic potential of neuroendocrine tumors of the pancreas, we advocate complete resection of all pancreatic cystic tumors, combined with careful sampling of the pathological specimen to rule out a coexistent potentially malignant neoplasm.

A 37-year-old black woman with nephritis secondary to systemic lupus erythematosus, steroid-induced diabetes mellitus, and hypertension presented with fever, nausea, vomiting, and right upper quadrant abdominal pain with distension. Abdominal computed tomography (CT) scan revealed a colonic mass, and CT- guided fine-needle aspiration demonstrated birefringent crystalline material. After several weeks of antibiotic therapy, the patient underwent laparoscopic examination followed by extended right hemicolectomy for a large mass in the subserosa of the transverse colon. Pathological examination of this mass revealed it to be a gouty tophus. To our knowledge, no case of tophaceous gout presenting as an intestinal mass has previously been reported

This article explores 3 aspects of breast diagnosis that are currently under investigation and about which our thinking has recently undergone considerable reshaping. The trend toward more frequent evaluation of clinically subtle lesions has suggested that it might be necessary to understand thefine-needle aspiration (FNA) presentation of proliferative breast disease. Efforts to do so, as well as our suggestions for additional studies and their potential limitations open this discussion. Following this section, the increasingly useful method of intraoperative cytology for evaluation of resected breast masses is considered in detail. In the final section, optimization of nonoperative sampling by combination of mammography, ultrasonography, fine-needle aspiration, and core biopsy is discussed and illustrated.

Fine-needle aspiration of the breast has become increasingly important as the standard of care for the evaluation of a breast lump. In this chapter the authors present a detailed discussion of breast masses, the basics of palpation and aspiration, and the evaluation of FNA smears in both benign and malignant breast disease.
