Ectopic immature renal tissue in gubernaculum associated with undescended testis of a 1-year-old child: A case report.

ABSTRACT

RATIONALE Ectopic immature renal tissue (EIRT) is extremely rare in congenital malformations. Moreover, the fundamental pathogenesis of EIRT is still unclear and controversial. PATIENT CONCERNS The right scrotum of a 1-year-old man was found empty for a period of 1 month. B-ultrasonography revealed normal bilateral kidneys and a hypoechoic nodule in the right groin. DIAGNOSES Based on B-ultrasonography, surgery and pathological examination, we concluded a case of abnormally located and EIRT in the inguinal canal. INTERVENTIONS: After pathological diagnosis, the patient was not treated with drugs. OUTCOMES: One year after the operation, the patient recovered. LESSONS EIRT in gubernaculum is extremely rare. Because of the potential risk of malignant transformation, it is necessary to diagnose and treat it early.
