Signet-ring cell (mucin-producing) adenocarcinoma of minor salivary glands: report of a case

Salivary gland tumors account for a significant group of head and neck neoplasms. Signet-ring cell (mucin-producing) adenocarcinoma of minor salivary glands was described by Ghannoum and Freedman in 2004. We report a case of this extremely rare minor salivary gland neoplasm in an 18-year-old male. To our knowledge, this patient is the youngest to ever be reported having this tumor.
