Upper gastro-intestinal bleeding - Rare presentation of renal cell carcinoma

Renal cell carcinoma (RCC) constitutes 2-3% of all adult malignancies and often diagnosed incidentally. Classical tried of RCC now rarely seen, it behaves unpredictably and having diverge range of clinical manifestation including paraneoplastic syndromes. Upper gastrointestinal (GI) bleeding due to stomach metastasis of RCC is uncommon and to the best of our knowledge, only few cases are reported in world literature and most of them were diagnosed during follow-up after complete treatment of RCC but in our case, it was the primary manifestation of disease. Our case also demonstrates the importance of imaging in undiagnosed cases of upper GI bleeding.

Unusual Renal Tumors — Report of Four Cases

Collecting duct carcinoma, plasmocytoma and malignant fibrous histocytoma are rare but aggressive tumors of the kidneys. We present four cases we have recently encountered in our practice. In most of the cases imaging did not help in the pre-operative diagnosis. Surgery is the mainstay of treatment when recognized early. Clinician should be aware about these rare varieties of renal tumors whose prognoses may be worse than that of renal cell carcinoma. The Annals of African Surgery, Volume 6, 2010
