A Case of Acinic Cell Carcinoma Associated with Ranula in Sublingual Gland / 대한이비인후과학회지

ABSTRACT

Acinic cell carcinoma (ACC) is a low-grade malignancy of salivary gland that constitutes approximately 17% of primary salivary gland malignancies. ACC predominantly occurs in the parotid gland. The higher incidence in the parotid gland seems to be related with the serous acinar cells of the glands, while the sublingual gland is a mixed gland, predominantly mucinous. Therefore, ACCs which originated in the sublingual gland are very rare and till now only 8 cases have been reported in the literature. Recently, we experienced a case of ACC which was found incidentally in the surgical specimen of a ranula arising in the sublingual gland. The finding of this case suggests that the early pathological diagnosis is needed to clarify the reasons for the recurrence of a ranula.
