The incidence of renal cell neoplasms has been increased in worldwide as well as in Korea. Even though the World Health Organization (WHO) Classification of renal tumors (2004) is currently used, new entities require to be added in the updated classification because of recent modification with our understanding of the molecular biology and different clinical behavior of new renal tumors. In this review, recently described tumors and candidate entities will be discussed. It is of importance to know these new entities for the proper diagnosis, treatment, and their prognosis.
Intraductal Carcinoma of the Prostate Gland: Recent Advances
Jae Y. Ro,Mukul K. Divatia 연세대학교의과대학 2016 Yonsei medical journal Vol.57 No.5
Intraductal carcinoma of the prostate (IDC-P) is characterized by prostatic carcinoma involving ducts and/or acini. The presence of IDC-P is usually associated with a high-grade Gleason score, large tumor volume, and adverse prognostic parameters, includingextraprostatic extension and seminal vesicle invasion. When present, IDC-P is associated with worse outcomes, regardless of treatment status. IDC-P is included in a broader diagnostic category of atypical cribriform lesions of the prostate gland. This categoryof lesions also includes high-grade prostatic intraepithelial neoplasia (HGPIN), urothelial carcinoma involving prostatic ducts or acini, and prostatic ductal adenocarcinoma, amongst other intraductal proliferations. Differentiating between these entitiesis important as they have differing therapeutic and prognostic implications for patients, although differential diagnosis thereof is not always straightforward. The present review discusses IDC-P in regards to its morphological characteristics, molecularfeatures, and clinical outcomes. Given the current state of knowledge, the presence of IDC-P should be evaluated and documentedcorrectly in both radical prostatectomy and needle biopsy specimens, and the clinical implications thereof should be taken into consideration during treatment and follow up.

Sarcomatoid carcinoma is a rare carcinoma which arises from upper respiratoy system, gastrointestinal tract, urinary tract and skin. Sarcomatoid carcinoma of larynx is rare so pathogenesis, clinical behavior, treatment and prognosis of it is being debated. Treatment of sarcomatoid carcinoma of larynx is similar to squamous cell carci-noma of larynx. We report a case of recurred sarcomatoid carcinoma after surgical treatment and postoperative radiotherapy.

<P>Using face annotation for effective management of personal photos in online social networks (OSNs) is currently of considerable practical interest. In this paper, we propose a novel collaborative face recognition (FR) framework, improving the accuracy of face annotation by effectively making use of multiple FR engines available in an OSN. Our collaborative FR framework consists of two major parts: selection of FR engines and merging (or fusion) of multiple FR results. The selection of FR engines aims at determining a set of personalized FR engines that are suitable for recognizing query face images belonging to a particular member of the OSN. For this purpose, we exploit both social network context in an OSN and social context in personal photo collections. In addition, to take advantage of the availability of multiple FR results retrieved from the selected FR engines, we devise two effective solutions for merging FR results, adopting traditional techniques for combining multiple classifier results. Experiments were conducted using 547 991 personal photos collected from an existing OSN. Our results demonstrate that the proposed collaborative FR method is able to significantly improve the accuracy of face annotation, compared to conventional FR approaches that only make use of a single FR engine. Further, we demonstrate that our collaborative FR framework has a low computational cost and comes with a design that is suited for deployment in a decentralized OSN.</P>
