Large tonsillolith mimicking peritonsillar abscess: a case report.

A case of large tonsillolith is described. A 26-year-old male presented with a history of recurrent throat infections. A diagnosis of peritonsillar abscess was made. A tonsillolith was spontaneously expelled on admission. A tonsillectomy was subsequently performed. The tonsillolith was yellowish-gray, measured 30 x 26 x 16 mm, and weighed 8.5 g, which was the largest reported case in Japan. Chemical analysis revealed the stone to consist of calcium phosphate.
