A Medical Marvel And Complex Clinical Scenario: The Largest Documented Case of Renal Metastasis from Pleomorphic Adenoma, Weighing 13.5 kg.

Abstract

Renal masses weighing as much as 13.5 kg are uncommon in the era of radiological imaging. A 52-year-old male presented with a left renal and parotid tumor with a history of parotidectomy 30 years back. He had an open radical nephrectomy followed by total parotidectomy. The patient had an uneventful recovery without any complications. The histopathology report of the renal tumor came as pleomorphic adenoma, while parotidectomy as carcinoma ex pleomorphic adenoma. This case highlights the indolent nature of pleomorphic adenoma presenting as delayed, huge renal metastasis. The thorough evaluation, accurate diagnosis, surgical excision of the tumor, and long-term close surveillance in pleomorphic adenoma are essential.
