Ossifying Renal Tumor of Infancy: Laparoscopic Treatment and Literature Review

Abstract

We present an unusual case of a rare ossifying renal tumor of infancy. A 6-month-old male initially presented with gross hematuria and without any palpable abdominal mass. Renal ultrasound and MRI showed a right lower pole, calcified, endophytic renal mass. Laparoscopic radical nephrectomy was performed without complications. Pathology demonstrated an ossifying renal tumor of infancy. We report this case, in addition to a review of the literature for similar cases, to highlight a rare renal tumor in infancy that can be managed laparoscopically.

Ossifying renal tumor of infancy: A case report

“…A safe laparoscopic nephrectomy in children with ORTI has been reported. 5 However, in specific cases, a radical nephrectomy may be considered necessary such as observed in our patient due to the persistence of arterial hypertension. Subsequently, a prolonged follow-up is imperative to ensure the absence of recurrence.…”

Ossifying renal tumor of infancy: a case report

“…Microscopically, the tumor has three main components: an osteoid core, osteoblast-like cells, and spindle cells. The central part of the tumor was an osteoid core, which is the typical morphological feature of this tumor, and the proportion and maturity of the osteoid core increased with age ( 5 ). Focal osteoblast-like cells were seen between the osteoid core, which were polygonal with large nuclei and abundant cytoplasm.…”
