Retroperitoneal ganglionörom
Nöroblastom, ganglionöroblastom ve ganglionörom sempatik sinir sistemini oluşturan, değişik derecelerde olgunlaşmış, primordial nöral krest hücrelerinden köken alan heterojen bir grup tümördür. Abdominal distansiyon, sol üst kadran ağrısı ve daire şikayetleriyle başvuran 12 yaşındaki erkek hastaya yapılan tetkikler sonucu rastlantısal olarak primer retroperitoneal ganglionörom saptanmıştır.Neuroblastoma, ganglioneuroblastoma and ganglioneuroma are tumors of varying maturity derived from the primordial neural crest cells that form the sympathetic nervous system. A primary extraadrenal retroperitoneal ganglioneuroma was found incidentally in a 12-year-old boy during a series of examinations for abdominal distension, left upper quadrant pain and diarrhoea
A case of urachal malacoplakia that seems like urachal cancer
Background: Urachal masses observed in adults should be considered malignant unless they are confuted. It is very difficult to differentiate between malignant or benign lesions, including especially calcified foci and solid areas. Case Report: Our case was a 63-year-old male patient who was diagnosed as Behçet’s Disease 26 years ago. Upon clinical examination, he was also diagnosed with adenocarcinoma of prostate. He was examined by computerized tomography to define the stage of prostatic adenocarcinoma. The existence of a hypodense multiseptated cystic lesion with irregular margins and solid areas located between anterosuperior of bladder and umbilicus was reported. Hence, the lesion was evaluated as urachal carcinoma and locally advanced prostate cancer by the urooncology council. Resection of the mass, partial cystectomy and pelvic lymphadenectomy were performed as one of the surgical approach options in urachal carcinoma. After pathological examination, the mass was diagnosed as malakoplakia and metastasis of prostate adenocarcinoma was also detected in the right obdurator lymph nodule. In the literature, case reports of urachal malakoplakia are extremely rare. It is also interesting to note the absence of specific clinical symptoms for the urachal mass and the existence of concomitant adenocarcinoma in our case. Conclusion: Malakoplakia can only be diagnosed by pathological examination. Particularly, urachal malakoplakia should also be taken into consideration in the differential diagnosis of lesions which include solid areas and are located in the urachus.

Case Report of An Incidental Unicentric Castleman Disease
DergiPark: 889347tmsjAims: To emphasize the hardship of diagnosing Castleman disease and present a potential treatment method. Case Report: A sixty-three-year-old male patient was admitted to the outpatient clinic with an attack of acute cholecystitis. The patient’s abdominal computed tomography revealed an incidentally detected lipid dense solid mass (64x53x37 mm) at the level of right renal hilum with 29x13 mm solid components in the middle. The patient was admitted to the urology department and underwent surgery where the mass was totally excised due to suspicion of a malignancy (liposarcoma). Histopathological examination later on resulted with unicentric Castleman disease, hyaline vascular subtype. Conclusion: Since unicentric Castleman disease has an asymptomatic clinical course and is quite rare, it is necessary to rule out many potential possibilities before reaching a proper diagnosis. However, unicentric Castleman disease usually exhibits a good prognosis after the removal of the affected lymph node. Still, Castleman disease should be a candidate considered in the differential diagnosis of patients with incidentally discovered lymphadenopathy. On the whole, for a better understanding of underlying pathophysiology, there still lies a gap to be filled with knowledge acquired through further studies
Protective Effect of Quercetin Against Renal Toxicity Induced by Cadmium in Rats
Objective: The aim of the present study was to examine the protective effect of quercetine (QE) against cadmium (Cd)-induced renal toxicity. Material and Methods: A total of 24 male Wistar albino rats were divided into three groups: control, Cd-treated and Cd-treated with QE; each group containing 8 animals. The Cd-treated group was injected subcutaneously with CdCl2 dissolved in saline in the dose of 2 ml/kg/day for 30 days, resulting in a dosage of 1 mg/kg Cd. The rats in the QE treated groups were given QE (15 mg/kg body weight) once a day intraperitoneally starting 2 days prior to Cd injection during the study period. Results: The renal histology in Cd-treated rats showed mesangial expansion, thickening of capsular basement membranes, glomerular basement membranes and tubular basement membranes, characterized by an increase in periodic acid Schiff (PAS)-positive areas as compared with control animals. With the QE treatment, despite the presence of only a few swollen glomeruli, we noticed a marked protection of renal structure when compared with the Cd-treated rats. Furthermore, QE pretreatment resulted in increased proliferating cell nuclear antigen (PCNA) immunoreactivity and decreased the activity of Terminal Transferase dUTP Nick End Labeling (TUNEL). Conclusion: These findings suggest that QE may attenuate Cd-induced renal toxicity
