Schwannomas are usually benign rare tumors that originating from Schwann cells of peripheral nerve sheaths. Presentation is generally varied and changed in a non-specific range from abdominal mass, flank pain to incidental findings. Herein we report 2 cases of retroperitoneal giant schwannomas with different clinical presentations, of whom one presented with vague abdominal pain, palpable abdominal mass for 4 years, swelling and bilateral hydronephrosis that caused by giant abdominal mass; the other one presented with right flank pain, rectal hemorrhage and lower extremities edema. Two patients were treated by complete surgical excision of masses. The histological and immunohistochemical diagnosis was reported as benign schwannoma. Both of patients are doing well and had no recurrence in 9 years and 28 months follow-up, respectively.
Hydatidosis is an endemic parasitic disease in Mediterranean region, Middle east, Australia, parts of Africa, Latin America and Turkey. The cysts are mostly evident in the liver or lungs, while urinary tract involvement is uncommon, comprising only 2-4 % of all cases. Isolated renal involvement is extremely rare. Its diagnosis may be difficult because of nonspecific complaints and absence of pathognomonic laboratory findings except from hydatiduria. Although radiological studies have a more important role in the diagnosis, they cannot always show a specific sign or lesion for hydatid disease. Herein we present a rare case with isolated renal hydatid cyst mimicking a renal mass treated with right radical nephrectomy. Isolated renal cyst hydatid should be considered in differential diagnosis of both cystic and solid renal masses.
Objective: The aim of this study was to evaluate the effect of gender on oncologic results in patients who have undergone radical cystectomy due to bladder cancer. Materials and methods:We retrospectively reviewed data from 460 patients who had radical cystectomy due to bladder cancer in our clinic. A total of 420 of the patients were men, and 40 patients were women. We evaluated the tumor type, tumor stage, tumor grade, lymph node involvement status, complications and survival rates of the females. These parameters were compared to male cystectomy data. Results:The median age of male and female patients was 60.59±8.966 and 63.2±7.816, respectively (p= 0.076). In total, 79.4% of the males and 70.3% of females had transitional cell cancer (p= 0.192). The detection frequencies for pT1, pT2, pT3 vs. pT4 stage tumors in males and females was 18%, 34.2%, 33.4% vs. 14% and 2.8%, 33.3%, 41.7%, 22.2%, respectively. The percentage of the lymph node involvement in female and male patients was 48.5% and 23.9% (p= 0.02). The grade 3 tumor involvement in female and male patients was 80.6% and 72.7% (p= 0.621). In females, the bladder-confined tumor percentage was 22.2% and males rate was 48.3% (p= 0.04). In terms of overall complications, no significant differences were found between males and females. Disease-specific survival (DSS) was 115±42.2 months in males and 18±2.14 months in females. Three-year DSS was 61.4% in males and 15.3% in females (p= 0.013). Median overall survival was 47±11.789 months in males and 18±1.581 months in females. Three-year overall survival was 53.2% for males and 11.4% for females. A significant difference was found between males and females (p= 0.013). Conclusion:In this study, we found that females present worse disease specific and overall survival rates than males due to poor prognostic factors such as lymph node involvement and the higher prevalence of extravesical disease in female patients.Key words: Bladder cancer; gender; radical cystectomy. ÖZETAmaç: Bu çalışmanın amacı mesane tümörü nedeniyle radikal sistektomi yapılan hastalarda cinsiyetin onkolojik sonuçlara etkisini değerlendirmektir. Gereç ve yöntem:Kliniğimizde mesane tümörü nedeniyle radikal sistektomi uygulanan 460 hastanın verileri retrospektif olarak incelendi. 420 erkek ve 40 kadın hasta çalışmaya dahil edildi. Kadın sistektomi olgularının tümör tipi, tümör evreleri, tümör derecesi, lenf nodu tutulum oranları, komplikasyonlar ve sağ kalım verileri değerlendirildi. Bu parametreler açısından erkek sistektomi olgularıyla karşılaştırıldı. Bulgular: Erkek hastaların yaş ortalaması 60.59±8.966, kadın hastaların yaş ortalaması ise 63.2±7.816 idi (p= 0.076). Erkek hastaların %79.4'ü transizyonel hücreli kanser iken kadın hastalarda bu oran %70.3 idi (p= 0.192). Kadın hastalarda pT1, pT2, pT3 ve pT4 evrelerinde tümör saptanma sıklığı sırasıyla %2.8, %33.3, %41.7, %22.2 iken erkeklerde bu oranlar sırasıyla %18, %34.2, %33.4 ve %14 idi. Lenf nodu tutulumu açı-sından olgular değerlendirildiğinde kadın hastalarda lenf notu tutul...
