Bony hamartoma of the inferior orbital rim in a patient with tuberous sclerosis.

flective, with a regular structure and moderate sound attenuation. This tumorwascharacteristicof pleomorphicadenomainseveralways. The patient had a painless change in appearance for at least 1 year. The lesionwasoval,wellcircumscribed,and appeared encapsulated on both computed tomographic and ultrasonographic studies. However, it showed significant,diffusecalcificationonboth imaging studies. In general, the presence of calcification is a radiological sign of malignancy, and calcification of masses of the lacrimal gland fossa usually suggests malignant disease. Only 3 histologically proven cases of pleomorphic adenoma with calcification can be found in the literature. Even in pleomorphic adenomas of the parotid gland, calcification is only rarely found and suggests an older tumor age. In summary, although calcification is more common in malignant lacrimal gland fossa tumors, the presence of calcification should not exclude a diagnosis of pleomorphic adenoma. Other clinical and radiological characteristics should be considered when planning surgical management.
