Benign hamartomatous polyp of the palatine tonsil.

A rare and possibly unique benign polypoid tumour of the palatine tonsil is described. It contained the two basic tissue types of the tonsil--lymphoid and epithelial--in the characteristic close anatomical relationship of tonsillar tissue. The features of this rare lesion lend support to the hypothesis that benign tumours of the tonsil may be hamartomas of tonsil or branchiogenic remnants rather than true neoplasms.
