The purpose of this study was to evaluate the spectrum of the Waldeyer’s ring tumor pathology. Waldeyer’s ring is a ringed arrangement of lymphoid tissue that surrounds nasopharynx and oropharynx. It consists of a pharyngeal tonsil, two tubal tonsils, two palatinal tonsils in the oropharynx, and lingual tonsil. The tonsils are made of heterogeneous tissues, therefore inside the tonsils proliferations could be neoplastic or reactive nature. The participants in our retrospective research were one thousand one hundred thirty patients with histopathology report of tumors of the Waldeyer’s ring. Seven hundred eleven where male and four hundred nineteen were female. The research was conducted at the Clinic for Otorhinolaryngology and Maxillofacial Surgery of the Clinical Center of Serbia from January 1, 2007 to December 31, 2017. The collected data was analyzed by descriptive and analytical statistic methods. It was found that the highest percent of participants developed reactive follicular hyperplasia (51,2%), 25.9% percent squamocellular carcinoma, 8.4% undifferentiated non keratinizing nasopharyngeal carcinoma, and 8.0% nonHodgkin lymphoma. The most malignant tumors were found among male participants over 60 years of age. The majority of malignant tumors grew in oropharynx. The most common tumor was squamous cell carcinoma.
