Renal inflammatory myofibroblastic tumor: A case report

Area of Science:

• Urology
• Pathology
• Oncology

Background:

• Inflammatory myofibroblastic tumor (IMT) is a rare neoplastic proliferation characterized by myofibroblastic spindle cells and an inflammatory infiltrate.
• IMT can occur in various locations within the genitourinary system, including the bladder, prostate, and kidney.

Observation:

• A 59-year-old male presented with abdominal pain, gross hematuria, and a renal mass.
• The patient underwent a partial nephrectomy for the renal mass.

Findings:

• The final pathological diagnosis was renal inflammatory myofibroblastic tumor.
• Preoperative diagnosis of renal IMT remains challenging despite advancements in imaging modalities.

Implications:

• Accurate diagnosis of renal IMT necessitates a combination of clinical interpretation, thorough histologic examination, and immunohistochemical studies.
• Definitive diagnosis is crucial for appropriate patient management and treatment planning for renal IMT.
