Malignant neoplasm arising from ileal ureter used for ureteral reconstructive surgery is an exceedingly rare event. Ureteroileoplasty was being performed since the beginning of the last century, but it was described more extensively in literature during the 1950s.1,2 Recurrent urinary infections, chronic renal failure, urolithiasis, anastomotic stricture, metabolic acidosis and chronic dilation of the graft had been described as late complications of ureteroileoplasty.3,4 Herein, we describe history, imaging and pathologic findings of a small bowel adenocarcinoma arising from ileal ureter in a woman of 78 year-old, subjected to ureteroileoplasty about forty years earlier...

OBJECTIVE: To evaluate the histopathological correlation of recently described subclassification of Bosniak category 3 cysts (3s and 3n). MATERIALS AND METHODS: A total of 106 patients who underwent partial/radical nephrectomy due to a complex renal cyst (≥Bosniak 3) were retrospectively reviewed. All the scans of the patients were reevaluated by two experienced uroradiologists. Bosniak 3 cysts were reclassified as 3n (nodularity on the cyst wall/septae) and 3s (septated cysts without nodularity) as described in a recently published paper...

OBJECTIVE: To quantify the use of downstream studies following staging bone scans in patients with muscle-invasive bladder cancer. Bone scans may be obtained in high-risk bladder cancer patients prior to radical cystectomy to exclude bone metastases. However, false positive bone scans can occur, resulting in the need for additional studies. PATIENTS AND METHODS: Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified 4404 patients diagnosed with muscle-invasive bladder cancer from 2004-2011...

Alveolar soft part sarcoma (ASPS) is a rare malignancy with high rates of metastasis at presentation, defined by an unclear cellular origin and a unique unbalanced ASPSCR1-TFE3 translocation (der(17)t(X:17)(p11:q25))1 . ASPS is insensitive to chemotherapy and has been reported to involve the bladder only twice in the pediatric literature; once as a primary malignancy2 , and once as a secondary malignancy after cytotoxic chemotherapy3 . Herein, we report the third case of pediatric bladder ASPS in a female patient who received cytotoxic chemotherapy for low-risk neuroblastoma...

Prostate-specific-membrane-antigen (PSMA) is a transmembrane protein with significantly increased expression in the cells and metastases of prostate carcinoma (PCa). PSMA-expression correlates with higher serum levels of prostate-specific-antigen (PSA) and a higher Gleason Score (GS). This finding has led to the development of novel imaging modalities such as 68Ga-/18F-labeled PSMA PET/CT and PET/MRI. This article reviews the literature pertaining to various new imaging technologies for the management of PCa...

OBJETIVES: To assess if 'tumour budding' (TB) behaves as a poor prognostic factor in muscle-invasive bladder carcinoma (MIBC). TB is the presence of tumour cells isolated or in small groups of fewer than five cells located at the tumour invasion front. MATERIAL AND METHODS: Retrospective study of 106 patients with MIBC who underwent radical cystectomy. A cytokeratin AE1/AE3 immunostaining was applied to identify and quantify TB by the 'hot-spot' method. The variables evaluated were: age, gender, TNM stage, associated CIS, differentiation degree, tumour size, tumour location, lymphatic, venous or perineural invasion, p53, Ki67, molecular subtype (basal/luminal) and chemotherapy...
