Giant cavernous hemangioma in renal graft: a case report.
BACKGROUND
We present a case of giant cavernous hemangioma in renal graft tumor; we have not found any cases described in literature.


METHODS
Patient transplanted from a deceased donor, 8 years previous to her admission due to deterioration in renal function, observing a 12-cm renal mass in the front face of the renal graft, which displaces it, provoking obstructive uropathy. On ultrasonography and computed tomography, it is seen as a complicated, cystic lesion. Tumorectomy with a good functional recovery of the graft was carried out. A histopathologic study showed a mass with extensive adherences to the perirenal adipose tissue and a cross section showed a spongy appearance with blood clots in the centre, microscopically formed by vascular channels, lined by a layer of endothelial cells, and filled with blood.


CONCLUSIONS
Giant cavernous hemangioma in renal graft tumor has not been previously described. Given its benign condition, nephron-sparing surgery should be carried out if possible.
