Objective: Bilateral renal cell carcinoma (RCC) is an extremely rare renal tumor, even more infrequently with two different types of pathology. Methods: We present a case of bilateral RCC with simultaneous retroperitoneal laparoscopic nephron-sparing surgery (RLNSS) in a 56-year-old male patient. Results: The postoperative histopathologic examination indicated that the left was clear cell carci...
RATIONALE Renal hybrid oncocytic/chromophobe tumors (HOCTs) are benign tumors containing a mixture of cells with features of chromophobe renal cell carcinoma (CHRCC) and renal oncocytoma (RO). Sporadic HOCT, which means HOCT occurs in patients without Birt-Hogg-Dubé syndrome (BHDS) or renal oncocytosis, is extremely rare. In this article, we would report a new case of a patient with both sporad...
Renal oncocytomas and chromophobe renal cell carcinomas (RCCs) share a common phenotype and both originate from the intercalated cells of the collecting duct. This makes it very difficult to differentiate between the two tumors immunohistochemically. Therefore, we studied the results of immunohistochemistry focusing on certain characteristic structures that are occasionally present in renal onc...
Birt-Hogg-Dubé syndrome (BHDS) is an autosomal dominant inherited disorder characterized by clinical features of skin lesions, pulmonary lesions and renal tumor. The gene responsible for this syndrome is located on chromosome 17p11.2 and designated as FLCN. In this article, we review renal tumors associated with BHDS with a focus on clinical and pathobiological aspects. Renal tumors often occur...
OBJECTIVE To determine the type of malignant renal tumours subjected to radical nephrectomy at a tertiary care urology unit using the 2004 WHO classification for renal tumours. METHODS It was an observational study conducted at Department of Urology, AFIU Rawalpindi, from October 2008 to September 2010. The study included 92 patients with malignant renal tumours of both genders aged above 15 ...
PURPOSE The chromophobe subtype of renal cell carcinoma (chRCC) has generally been associated with a better prognosis than the clear cell type; however, debate continues as to absolute prognosis as well as the significance of certain prognostic variables. We investigated the significance of pathologic stage and a recently proposed chromophobe tumor grading (CTG) scheme in predicting chRCC outco...
