An Unusual Case of Lymphadenophaty of The Retropharyngeal Space in Recurrent Maxillary Sinus Carcinoma: Case Report

Retropharyngeal lymph nodes (RPLNs), particularly the lateral group known as Rouvière’s nodes, represent an uncommon but clinically significant pathway for metastatic dissemination in head and neck malignancies. Their deep anatomical location, limited clinical accessibility, and exclusion from standard neck dissection procedures make their assessment challenging. Although frequently associated with nasopharyngeal and oropharyngeal carcinomas, metastatic involvement secondary to maxillary sinus carcinoma is rare. We report the case of a 72- year-old male with a history of squamous cell carcinoma of the maxillary sinus previously treated with definitive radiotherapy and concurrent chemotherapy.
