Tubulocystic carcinoma (TCC) of the kidney is a unique, rare, and recently recognized neoplasm. Although originally considered a low-grade collecting duct carcinoma, TCC is now considered to be a distinct entity. TCC should be considered in the differential diagnosis of cystic renal neoplasms. We report a case of TCC arising in the left kidney.

renal transplantation is considered one of the best long-term therapies for chronic renal failure, but unfortunately the incidence of malignancy significantly increases in renal transplant recipients. we analyzed nine cases of malignancy in 200 renal transplant recipients occurring in a 12-year follow-up in imam hospital of tehran university, tehran, iran. according to this study, the organ mos...

Primitive  neuroectodermal  tumor  (PNET)  of  kidney  is  an  extremely  rare  renal  neoplasm  with only about fifty reported cases in literature.  Presumably,of neural crest origin, these tumors behave  aggressively  and  carry  a  poor prognosis.  We  report  a  case  of  22-year  old  female  patient complaining of left loin pain with recurrent hematuria for last 3 months. On clinical ex...

Primary osteosarcoma of the kidney is a very rare neoplasm with a very poor prognosis and unclear histogenesis. Only 20 cases have been reported in the literature. It has a strong tendency to recur locally and spread to distant sites. We present the clinical case of a 79-year-old man affected by a primary osteosarcoma of the kidney presenting with substantial retroperitoneal tumor hemorrhage. L...

Renal angiomyolipoma is an uncommon, benign neoplasm. Although it is seen in association with tuberous sclerosis, the majority (80%) occur in isolation. Isolated tumours predominantly occur in middle aged females, and mostly arise from the right kidney [1]. Larger tumours are known to be associated with a significant risk of rupture (traumatic or spontaneous) resulting in haemorrhagic complicat...

Reported is the case of a 17-year-old girl with a multicystic tumor in the middle of the right kidney. Partial nephrectomy revealed an epithelial neoplasm with multilocular cystic renal cell carcinoma pattern. The cells exhibited strong nuclear reactivity for TFE3 protein and supported the diagnosis of Xp11 translocation carcinoma of the kidney. A similar case has not been found in the literatu...

Malignant rhabdoid tumors (MRT) of the kidney are rare in children and even less common in adults, with only six previously reported adult cases. We present the case of a 60-year-old man with an MRT arising in the left kidney with extensive pulmonary micrometastases and thromboembolism resulting in thrombotic pulmonary microangiopathy (pulmonary tumor embolism syndrome). MRT is an extremely agg...

OBJECTIVE The present study aimed to establish reference intervals for serum cystatin C (Scys-C) stratified by stages of chronic kidney disease, explore factors influencing Scys-C and compare the performance of Scys-C with serum creatinine (Scr) in the young and elderly. METHODS A total of 800 participants, 516 young (<60 years) and 284 old (≥60 years) subjects were included in this study. Sc...
