Renal cystic masses are although known to occur frequently with varied diverse presentation and symptoms, we report here
an exceptionally unusual case in which epidermoid cyst was diagnosed of the left kidney in a 46-year female. She came with the
presenting complaints of intermittent pain, dull in nature in the left loin for 8 months. Radiological Imaging was advised which
revealed a cystic lesion of left kidney that was thought to be neoplastic. CT guided biopsy was performed from multiple areas of
the cyst bearing kidney to ascertain the nature preoperatively. Histopathological evaluation concluded it be an epidermoid cyst
of kidney which is very rarely encountered with only a few reported cases in the literature. Better clinical awareness and timely
preoperative diagnosis is essential to prevent radical surgery.
