A 38-year-old male presented with right hypochon-dralgia and backache for two rears. Plain X-ray KUB showed a radio-opaque calculus in the left renal area. Urinalysis and culture were negative. IVU (after a nor-mal serum urea and creatinine report) showed the char-acteristic tooth-like calcification to be situated above and medial to the upper pole of left kidney which itself is de-formed and pushed downwards. CT scan with contrast showed a mass of approx. 6.5 x 6.5 cm with central hypodense area and surrounding dense wall adherent to the adjacent retroperitoneum and major vessels. A solid calcified element (dermoid plug) was seen projecting into the cavity. On exploration, the para-adrenal mass was found to be adherent to the aorta and adjacent struc-tures. The offensive cheesy content was first removed, followed by gradual and careful separation of the wall in parts, thus avoiding injury to the major vessels. The wall contained several abortive tooth structures, hair shafts and skin-like lining. Histopathology showed sev-eral ectodermal structures (tooth, hair follicles, sweat and sebaceous glands etc), but no immature element. The patient recovered uneventfully and is doing well at present.
