"Benign" metastasizing pleomorphic adenoma. A case report and review of literature.
A case of a 34-year-old man with a pathologic fracture through a lytic lesion in the left glenoid is presented. The results of a needle biopsy of the lesion showed a benign pleomorphic adenoma. Sixteen years previously, the patient had a pleomorphic adenoma of the parotid gland. Histology of the initial tissue and the needle biopsy specimen were identical. The patient developed metastasis without any local recurrence of the initial tumor. When evaluating a patient with a lytic lesion of bone with a history of a benign pleomorphic adenoma of the salivary gland, a metastasis should be considered.
