Cytological Features of Sialoblastoma: A Case Report With Summary of Prior Published Cases

Background: Sialoblastoma is an uncommon salivary gland neoplasm seen predominantly in the paediatric age group. It poses diagnostic challenges to the pathologists because of its rarity.

Case report: Here, we present the cytological features of a case of sialoblastoma in 5-month-old baby boy on imprint cytology. The smears were fairly cellular and composed of clusters and dispersed population of small round basaloid cells with occasional duct formation.

Conclusion: Sialoblastoma should be considered in the differential diagnosis of paediatric salivary gland tumours. It needs to be differentiated from other small round cell tumours of childhood and tumours composed of basaloid cells. Here, we discuss the cytological differentials of sialoblastoma along with a summary of prior published cases.
