Most bladder tumors are derived from the urothelium. Benign mesenchymal tumors are rare. Leiomyomas account for less than 0.43% of all bladder tumors. Genitourinary leiomyomata may arise in any anatomic structure containing smooth muscle. They have been reported to involve single or multiple organs. Since they may also mimic malignant lesions, they should always be considered in the differential diagnosis of any pelvic mass, with a possibility of being asymptomatic and discovered incidentally by radiographic imaging. We, herein, report a case illustrating clinical and pathological features in particular immunohistochemistry, and discuss its etiology and differential diagnosis.
ÖzetAmaç: Serviks kanseri, gelişmekte olan ülkelerde kadınlarda kansere bağlı ölümlerin önde gelen nedenidir. Bu makalede, bölümümüze başvuran kadın hastaların klinik parametrelerini değerlendirerek, smear sonuçları ile karşılaştırmak istedik. Gereç ve Yöntem:Kadın doğum polikliniğimize 2010-2011 yılı arası başvuran 1101 kadının Bethesda sistemine göre değerlendirilen smear sonuçları, retrospektif klinik verilerle değerlendirildi. Bulgular:Yaş arttıkça enflamasyon tanısının normal izlenmesine oranla anlamlı olarak azaldığı (p=0.001), akıntı-ağrı şikayetinin anlamlı olarak arttığı (p<0.0001), kanama ve kitle hissi şikayetinin değişmediği saptandı (sırasıyla, p=0.978 ve 0.688). Mann-Whitney U testi ile rahim içi araç (RİA) varlığı durumunda aktinomiçes enfeksiyonunun, RİA yokluğu durumuna oranla anlamlı olarak arttığı gözlendi (p<0.0001). Pap smear sonuçlarına bakıldığında, önemi bilinmeyen atipik skuamöz hücreler/düşük dereceli skuamöz intraepitelyal lezyon (ASC-US/LSIL) oranı %11.1 olduğu tespit edildi.Sonuç: Servikovajinal tarama yönteminin, en güvenli ve en kolay tarama yöntemi olduğunu ve gereği halinde doku biyopsisi ile erken tanı şansının daha da yükseleceğini umuyoruz.
Background: Colon cancer is one of the most common cancers worldwide. Apoptosis is a necessary physiological process for cell elimination which is very important both cellular homeostasis and cell proliferation and differantiation. Dysregulation can lead to uncontrolled cell growth and tumor development. Survivin, a member of the IAP family, plays a key role in promotion of cell proliferation as well as inhibition of apoptosis in cancer cells. The aim of this study was to investigate whether specific genetic polymorphisms of survivin could be associated with colon cancer development and progression in a Turkish population. Our study is the first to our knowledge to investigate the relationship between colon cancer risk and survivin gene polymorphisms. Materials and Methods: The relation between colon cancer and survivin -31 G/C (rs9904341), -241 C/T (rs17878467) and -625 C/G (rs8073069) polymorphism in promotor site of survivin gene associated with apoptosis was investigated using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results: Individuals with -31C allele and CC genotype were found to have a higher risk of developing colon cancer (OR=13.4, p=0.01). The -241 CT genotype considerably increased the risk of colon cancer (OR=12.0, p=0.0001). However, there was no significant varaition of the survivin -625 C/G polymorphism among colon cancer patients and controls in our study. Conclusions: This study provides the first evidence that survivin -31 G/C and -241 C/T SNP significantly contribute to the risk of colon cancer in the Turkish population.
Basal cell carcinoma (BCC) is a malignant neoplasm derived from nonkeratinizing cells that originate from the basal layer of the epidermis and it is the most common type of skin cancer in humans. Giant BCC (i.e. greater than 5 cm in diameter) is quite rare and comprises 0.5 percent of all BCC. Despite the high incidence of BCC, metastasis of this tumor is rare, with rates ranging from 0.0028% to 0.55% of all BCC cases. In this case, the tumour reached a giant size and had a pulmonary metastasis.,We aimed to emphasize that although BCC's are usually indolent; the importance of adequate surgery and chemoradiotherapy should always be considered in indicated cases. Keywords: Basal cell carcinoma, metastasis, giant size, adequate surgery ÖzetBazal hücreli karsinom (BHK) epidermisin bazal tabakasından kaynaklanan ve nonkeratinize hücrelerden oluşan en yaygın cilt tümörüdür. Dev BHK (yani çapı 5 cm'den büyük) oldukça nadirdir ve tüm BHK'ların %0,5' ini oluşturmaktadır. BHK insidansı yüksek olmasına rağmen, bu tümörün metastaz oranı tüm vakaların %0,0028-%0,55 arasında değişmektedir. Bu vakada tümör dev boyuta ulaştı ve akciğer metastazı vardı. Burada, BHK'lar genellikle yavaş seyirli olmasına rağmen gerekli vakalarda yeterli cerrahi ve kemoradyoterapinin önemini vurgulamak istedik.Anahtar sözcükler: Bazal hücreli karsinom, metastaz, dev çap, yeterli cerrahi Geliş tarihi
The DBM + TCP + HA combination should not be used for graft repair, although it was thought to be a good combination in the early weeks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
