Challenges in Diagnosing Rare Retroperitoneal Tumors: A Case Report of Extrarenal Giant Angiomyolipoma.

ABSTRACT:

Introduction

Extrarenal angiomyolipomas are extremely rare tumors, with only isolated reports in the literature. Their diagnosis is challenging as these lesions are often misdiagnosed as more common retroperitoneal tumors. This report presents a case of a retroperitoneal extrarenal angiomyolipoma, emphasizing its clinical, imaging, and histopathological features to facilitate accurate diagnosis and avoid errors.

Case presentation

A 58-year-old male with a history of benign prostatic hyperplasia presented with progressive abdominal distension and weight gain. Imaging studies revealed a giant retroperitoneal mass displacing the left kidney and abdominal aorta. A core needle biopsy initially suggested a well-differentiated liposarcoma T4N0M0, leading to neoadjuvant chemotherapy
