Abstract :

Aims: An overall assessment of the clinical behaviors ,histopathological features of non clear cell tumours of kidney Materials andMethods: Retrospective evaluation of uncommon renal neoplasm in a tertiary care center. Twenty cases of uncommon renal tumors were diagnosed in our institution . Results: Out of 20 cases, fifteen were seen in adults and five in pediatric age group.rare cases in pediatric age group were 2 cases of clear cell sarcoma (CCS) , one case of rhabdoid tumor , one case of congenital mesoblastic nephroma , one case of multilocular cystic nephroma .Among the adults there were four cases of chromphobe renal cell carcinoma ,three cases each of papillary renal cell carcinoma and renal medullary carcinoma,two cases of oncocytoma,one case each of metanephric adenoma,primitive neuroectodermal tumour and leiyomyosarcoma. Conclusion: The clinical presentations of these uncommon renal tumors are similar to that of clear cell renal carcinoma tumor. Thus, preoperative diagnosis is difficult even with modern imaging techniques. Some of these tumors (CCS, rhabdoid tumor) are rapidly progressing and have a poor outcome. Hence, early intervention in the form of complete surgical resection of the tumor (whenever possible) and postoperative chemo/radiotherapy are imperative for fruitful outcome.
