Abstract

We report an unusual presentation of a Wilms' tumor in an 8-month-old child, incidentally detected by ultrasonography for an umbilical granuloma. A patent vitellointestinal duct anomaly required surgical excision in the same sitting as the nephroureterectomy. The case is reported for the unusual coexistence and the management implications.

Introduction

Umbilical granuloma is common in infants and usually responds to common salt local application. It is to be borne in mind that not all umbilical lesions are granulomas and when not responding to treatment getting ultrasonography (USG) to rule out vitellointestinal duct (VID) or urachal anomalies is prudent.[1] In the index case, the USG also picked up a Wilms' tumor in the right kidney which has not been reported in literature previously.

Case Report

A full-term male child had a persistent red fleshy mass at the umbilicus not responding to local application of antibiotic ointment and silver nitrate. He was well with no complaints other than a minimal serosanguinous discharge from the umbilicus. At 7 months of age, he was referred for surgical excision of the umbilical mass. An USG of the abdomen done just before referral, however, picked up a large right renal tumor. A Wilms' tumor was diagnosed on fine-needle aspiration cytology at our center. Contrast-enhanced computed tomography of the abdomen revealed a 9 cm × 6 cm × 8 cm tumor arising from the lower pole of the right kidney [Figure 1]a. The tumor showed a significant reduction in size after four cycles of chemotherapy with Actinomycin D and vincristine. At laparotomy, a broad-based Meckel's diverticulum with a patent duct leading up to the umbilical granuloma [Figure 1]b was found. Wedge resection of the Meckel's diverticulum was done along with a right radical nephroureterectomy. The child had an uneventful postoperative period. Histopathology confirmed triphasic Wilms' tumor [Figure 2]. He is doing well at 6 months of follow-up.

Discussion

Wilms' tumor is the most common childhood abdominal malignancy forming 6% of all childhood cancers with a 5-year survival rate of nearly 90%.[2] Presenting features include abdominal mass, pain, hematuria, and fever. In the normal population, there is a 2% incidence of VID anomalies which may remain silent throughout life. The spectrum of anomalies includes fistula, sinus tract, cyst, mucosal remnants, and congenital bands. A study of 16 infants with VID revealed the most common presentation to be patent VID with visible bowel loop and/or fecal discharge with an umbilical granuloma seen only in 12.25% of patients.[3]

Intra-abdominal malignancy is known to cause umbilical deposits in adults, also called Sister Mary Joseph's nodule, secondary to spread through the lymphatics and venous channels draining along the abdominal wall.[4] This phenomenon is not known in children, and the umbilical mass, in this case, was soft and granulomatous as opposed to hard and skin covered. It would appear that the two conditions existed coincidentally but the persistence of the granuloma at 7 months age led to the USG detection of the VID and the renal tumor which could be excised in the same sitting without any additional morbidity.

Wilms' tumor is less frequent in infants but associated with a better prognosis.[5] Due to an association with favorable histology, they may be treated with surgical resection alone. Early detection is possible if frequent well-child check-ups are done in the 1st year of life. If our case did not have the associated granuloma, he may have presented later with metastasis. A literature search of surgical conditions that preceded the diagnosis of Wilms' tumor revealed only one report of a 5-year-old that presented with a perforated appendix and was detected to have a renal mass on imaging. The child underwent an appendectomy followed by an open biopsy of the renal mass which revealed Wilms' tumor.[6]

Conclusion

This is an unusual presentation of Wilms' tumor in an infant which has not been reported before. It is hoped that early management will improve the long-term outlook for this patient.
