Cartilaginous choristoma of tonsil: A hidden clinical entity
A 24-year-old male presented to the Ear, Nose, and Throat (ENT) Department with history of recurrent sore throat, pain, fever, and painful swelling. On examination, tonsils were persistently enlarged and white flakes were present on the tonsil. A clinical diagnosis of tonsillar keratosis was made. Tonsillectomy was performed and the specimen was sent for histopathological examination. Both the specimens from the right and left tonsils measured approximately 3 cm × 2 cm × 1.5 cm. Cut-section was grey in color and gritty to cut. Microscopic examination revealed lining of stratified squamous epithelium which at places had invaginated into the deeper tissues forming blunt ended crypts []. The subepithelial region contained numerous lymphoid follicles showing follicular hyperplasia with adjacent fibrocollagenous tissue. Numerous islands of mature cartilage were seen embedded in the fibrocollagenous tissue []. A diagnosis of cartilaginous choristoma was given.
