Appendiceal mucinous neoplasms: controversial issues.
Low grade appendiceal mucinous neoplasms can spread to the peritoneum as pseudomyxoma peritonei even though they are not obviously invasive in the appendix. During the past several decades, several problematic issues surrounding this enigmatic tumor have been debated in the literature, including appropriate nomenclature for the appendiceal tumors and their peritoneal metastases. In this article...
متن کاملMucinous appendiceal neoplasms: preoperative MR staging and classification compared with surgical and histopathologic findings.
OBJECTIVE The objective of our study was to determine the accuracy of MRI in the preoperative staging and classification of mucinous appendiceal neoplasms and to describe the MRI features that are useful for selecting patients for surgical resection. MATERIALS AND METHODS Twenty-two patients underwent preoperative MRI including T1-weighted, T2-weighted, immediate gadolinium-enhanced, and dela...
متن کاملMucinous appendiceal neoplasms. Do we all speak the same language?
Appendiceal tumors are unusual entities representing around 1% of the appendicectomies, and 0.5% of the gastrointestinal neoplasms (1). The mucinous adenoma is one of the most prevalent primary appendicular neoplasms, more frequent in middleaged women. The diagnosis is usually a casual finding in the anatomopathologic study after an appendicectomy performed in a patient with clinical suspect of...
متن کاملImmunoexpression of napsin a in renal neoplasms
BACKGROUND Immunohistochemistry (IHC) for napsin A has been widely used to support a diagnosis of lung adenocarcinoma with high sensitivity. In this study, we evaluated immunoreactivity for napsin A in a broad spectrum of renal neoplasms by using tissue microarrays (TMA). METHODS Duplicate TMA of 159 surgically excised renal neoplasms of various types were constructed. IHC for napsin A was pe...
متن کاملFactors in intraductal papillary mucinous neoplasms of the pancreas predictive of lymph node metastasis.
BACKGROUND Little is known about the frequency of lymph node metastasis (LNM) in intraductal papillary mucinous neoplasms (IPMNs), and we have not been able to determine how much lymph node dissection is necessary in individual cases. The aim of this study was to investigate the predictive factors for the LNM in IPMNs. METHODS Medical records of 120 patients pathologically diagnosed as having...
