PURPOSE
Ectopic immature renal tissue (EIRT) is a rare entity, with few cases described in the literature. Its difficult diagnosis as
well as potential association with extra-renal Wills tumor makes the clinical orientation of these patients a difficult and
important issue.
MATERIAL AND METHODS
We report a case of a 1 year old boy that underwent right orchiopexy because of an inguinal testis. During the
procedure we identified a dark, firm, small mass adherent to the spermatic cord. Complete resection of the ectopic
tissue was accomplished and sent for hystopatological analyses. The surgical procedure underwent without any
complication.
RESULTS
The tissue was compatible with EIRT, with no malignant transformation. The post-operative period was uneventful.
There were no other findings on physical exam and clinical and imagiological follow-up was the treatment of choice.
CONCLUSIONS
EIRT is a rare entity, with scarce literature on the matter. Until now there have been few case reports in the literature of
EIRT, and even fewer cases identified in the inguinal canal. To our knowledge, there is only one report of EIRT in the
spermatic cord associated with extra-renal Wilm's tumor (ERWT).
We present one of the few cases of EIRT in the inguinal canal. What we know from previous studies is that the
histological analysis of EIRT and the diagnosis between EIRT and ERWT is a difficult one to make and bares clinical
implications. So whenever an ectopic mass is encountered in the spermatic cord during inguinal surgery, it should be
excised for hystopatological analyses.
