Sialoblastoma: a rare cause of pleural metastasis

Abstract

Sialoblastoma is rare low-grade malignant tumor which is originated from parotid or submandibular gland. Although this tumor can be successfully treated surgically, distant metastases to different anatomical regions may be seen depending on the histopathological features of the tumor. In this article, we present a 11-year old patient who underwent an operation due to ectopic sialoblastoma and had pleural metastasis during the follow-up. To the best of our knowledge, this is the first case report of sialoblastoma-related pleural metastasis.
