Background: Collecting duct carcinoma of the kidney is one of the rare malignancies of the kidney but highly aggressive one arising from distal part of the nephron in medulla. Early diagnosis may help in prolonged survival of the patients. Objective: To know the clinical, radiological and histopathological features of collecting duct carcinoma helping in early diagnosis and treatment in further patients. Methods: An institution based retrospective study of five patients including follow up period of minimum 6 months was performed. Result: A total of 5 cases (4 males and 1 female) were analysed with average age of 56.4 years with range from 48 to 65 years. All patients were having flank pain with 2 of them also having history of haematuria. None of the patients were having hypercalcemia.CECT abdomen and pelvis was done in 4 patients while MRI abdomen and pelvis along with Doppler of renal vein with IVC was done in one. Of all the tumours three were solid and rest two were complex solid and cystic with average size of 4.7 cm. In 4 patients tumours were arising from central portion of renal parenchyma while in 1 arising from pelvic –ureteric junction radiologically. Regional lymph nodes were enlarged in 4 patients. Radical nephrectomy was performed in 4 patients while one patient underwent nephroureterectomy with bladder cuff excision. On HPE all were confirmed CDC with regional LNs and renal sinus involvement in 4 cases. 2 cases were showing involvement of renal pelvis along with breach of renal capsule while one was having ureteric extension. On IHC all 5 cases were CK19 +ve, 4 cases were CK7+ve while one was negative. Conclusion: CDC of kidney exhibits diverse but some special clinicopathological features which may help in early diagnosis/suspect and early treatment. As it is one of the aggressive malignancies with poor outcome early treatment may prolong the survival..
