A rare case report of primary renal squamous cell carcinoma

Abstract

Primary renal squamous cell carcinoma is a very rare entity. Only few cases are reported in the world literature. Most of the patients present at a late stage resulting in poor prognosis. We report a 44 year old female who presented with a history of lump in right flank accompanied with a dull intermittent pain for 2 months duration which intensified in the last 15 days. Antecedent risk factors like renal calculi, analgesic use were absent. Computed Tomography (CT) examination revealed a mass arising from the superior pole of kidney with extension to the posterior segment of liver. Histopathology following nephrectomy showed histological features of well differentiated squamous cell carcinoma.
