Cartilaginous choristoma of tongue: A rare case report

Choristomas are proliferation of normal cells or tissue in an abnormal location. Choristomas of oral soft tissue are rare lesions. Different tissues can occur in the oral cavity as choristomas. It can be cartilage, bone, salivary gland, glial and thyroid tissue. Choristomas with the proliferation of chondroid tissue are termed as cartilaginous choristomas. In oral cavity, they are most frequently seen in tongue followed by buccal mucosa and soft palate. We report a case of 40-year-old female presenting with hard lobulated swelling on the left lateral border of the tongue. Fine-needle aspiration cytology was performed which showed only myxoid stroma. Histopathological examination of excised specimen of the same showed lobules of mature hyaline cartilage. Thus, a diagnosis of cartilaginous choristoma was made.
