Recurrent mixed tumor.
Recurrence of benign neoplasms can usually be attributed to incomplete excision. Such is the case with benign mixed tumors of salivary glands. Certain histopathologic features of mixed tumors, however, appear to facilitate recurrences. These are: a predominantly myxoid composition, and transcapsular extension by the tumor. Multicentric origin is possible, but it must be regarded as a much lower order of probability.
