Purpose: This article analyzes osseous lesions in the tongue with rega
rd to the clinical and histologic features and discusses the pathogene
sis and terminology of these lesions. Materials and Methods: Thirty-ei
ght cases of lingual osseous lesions were retrieved from the English l
anguage literature, and two new cases were added. Results: The lesions
had a female predilection, with a female-to-male ratio of 2.3:1. Mean
age of the patients at time of diagnosis was 31.4 years. The lesions
were located in the posterior third of the dorsum of the tongue in 67.
5% of the cases, in the lateral margins in 25%, and in the mid-third o
f the tongue in 7.5%. Size ranged from 0.5 to 5.0 cm. Duration of the
lesions ranged from several months to 50 years. In eight cases, there
was information that the lesions had increased in size. Histologically
, the lesions appeared a well-circumscribed mass of vital bone under t
he surface epithelium. The two new cases, when examined by polarized l
ight, showed a mixture of woven and mature bone. Conclusion: The osseo
us lesions of the tongue represent a heterogeneous group of lesions in
which some may represent a developmental malformation, and others may
be a reactive lesion after trauma or irritation. Some lesions behave
as true neoplasms and others as choristomas. It is suggested that the
descriptive term ''osseous tumorlike lesion of the tongue'' may be mor
e appropriate for this group.
