A concealed giant peritonsillolith masquerading as oropharyngeal tumor.

Tonsillolith is defined as concretion of calcified materials in the crypt of palatine tonsil. Small tonsillolith is relatively common and can occur up to 10% of the population but due to the asymptomatic nature of this condition, most cases go unreported. Symptomatic patients can present with foreign body sensation, halitosis, sore throat, odynophagia and in certain cases even dysphagia or referred ear pain. Large or giant tonsillolith are fairly uncommon. Calculi found in the peritonsillar space or also known as peritonsillolith are even rarer. Peritonsillolith was first described in 1975 and since then there are only few literatures describing this entity. A giant peritonsillolith that is properly concealed by tonsil substance or mucosa may present as oropharyngeal mass that mimics tumor. We report an extremely rare case of giant peritonsillolith that underwent diagnostic tonsillectomy and surgical excision.
