Renal Myxoma- A Rare Variety of Benign Genitourinary Tumour

Abstract

Renal myxomas are rare neoplasms and very few cases have been reported in literature. Here we report a renal myxoma in a 48- year-old lady with hypothyroidism who presented with abdominal pain. She was found to have a mass lesion of 67 x 61 x 74 mm with exophytic component in the right kidney on ultrasonography and computed tomography. Right radical nephrectomy was performed due to suspicion of malignancy. Grossly the resected kidney showed a gelatinous, semi-translucent mass involving the mid and lower poles. Microscopy revealed marked hypocellular appearance of loose myxoid tissue with foamy histiocytes. Tumour cells were reactive for vimentin. At eight months of follow-up, patient is doing well.
