Salivary gland tumours are rare tumours characterized by histopathologic complexity and a wide variety of morphologic features. Studies on genetic changes in different histological subtypes of salivary gland tumours are important to better understand molecular pathogenetic mechanisms and to identify diagnostic and prognostic markers. Data are even more scanty dealing with unusual subtypes of th...

The papillary cystic variant of the acinic cell adenocarcinoma is a rare salivary gland tumour, which may behave in an unpredictable manner and exhibit non-specific histological features. Its diagnosis is important as it may prognosticate for a poorer outcome and it has been reported to universally fatal. We present a case of this unusual tumour and discuss the diagnostic and management difficu...

The origin of a salivary gland tumour is attributed to cells at various levels of differentiation which present histologically as diverse tissues and cellular patterns. Mitochondria-rich, eosinophilic oncocytes are cells commonly encountered in salivary gland neoplasms. We report a case of mucoepidermoid carcinoma (MEC) in the palate of a 43-year-old female that exhibited a prominent oncocytic ...
