Rare Vocal Cord Metastasis From Prostate Adenocarcinoma on 68Ga-PSMA PET/CT: A Diagnostic Mimic.

Source: PubMed, NCBI / U.S. National Library of Medicine

Malignant laryngeal lesions are most commonly primary tumors, predominantly squamous cell carcinoma. Metastatic involvement of the larynx is extremely rare. Among metastatic tumors, renal cell carcinoma, melanoma, lung cancer, and breast cancer represent the most frequent primary sources, whereas metastasis from prostate adenocarcinoma is exceptionally uncommon. Here, we present a case of vocal cord metastasis from prostate adenocarcinoma that was initially detected on 68Ga-PSMA PET/CT and remained clinically silent for a prolonged period.
