Multiple neoplastic intracerebral aneurysms associated with renal cell carcinoma

a patient with multiple myeloma and renal cell carcinoma

the coexistence of two malignancies is rarely seen. a little association between hematologic malignancies especially multiple myeloma and renal cell carcinoma has been reported in the recent past. several case series revealed a bidirectional association between these two malignancies which may be due to the common risk factors, similar cytokine growth requirements and clinical presentation. her...

Sarcomatoid Chromophobe Renal Cell Carcinoma with Heterologous Component

Clear cellrenal cell carcinoma (RCC) is the most common malignant renal tumor in adults, while chromophobe RCC (CRCC) is the third most common. Any subtypes of RCC can undergo sarcomatoid differentiation, but heterologous differentiation in sarcomatoid area is very rare in RCC. Here a61-year male is presented with hematuria and palpable mass. Clinicoradiologically, RCC was considered and left r...

Paraneoplastic Glomerulopathy Associated with Renal Cell Carcinoma

Renal cell carcinoma is often associated with paraneoplastic syndromes caused by the secretion of tumor cell products such as hormones, cytokines, growth factors and tu‐ mor antigens, which show manifestations including impaired glucose metabolism, hy‐ percalcemia, hypertension, Cushing syndrome, polycythemia, thrombosis, eosinophilia, leukemoid reactions and amyloidosis [1]. It has been report...

Retroperitoneal fibrosis associated with renal cell carcinoma.

Retroperitoneal fibrosis is a rare condition. It is idiopathic or secondary to various diseases including autoimmune diseases and atherosclerosis [1]. Although its pathogenesis is unknown, it is now considered that immune responses may play an important role in this disease [1]. Retroperitoneal fibrosis is also seen in metastatic carcinomas from many organs as a desmoplastic reaction [1]. Howev...
