Introduction: Acinic cell carcinoma is an uncommon low grade tumour of the salivary glands that constitutes 2.5
to 4% of parotid gland tumours. Acinic cell carcinoma -Papillary cystic variant (ACC-PCV) is histologically composed
of tumor with papillary and cystic growth patterns, with varying proportions of one or more cell types. It has
been conferred significance because it has a poorer prognosis and is reported to be universally fatal in ten years.
Case Report: We present a case of ACC-PCV in a sixteen year old male with unusual unicystic gross appearance,
benign cytological picture and characteristic histopathological features .Cystic areas with papillary projection of
surrounding cells showing characteristic tombstone or hobnail arrangements were seen.
Discussion: The histogenesis and myriad architectural and cellular variations of ACC-PCV have been discussed
along with its variegated cytomorphology which may lead to pitfalls in cytodiagnosis. The tumor may pose difficulty
in histodiagnosis due to its resemblance to papillary carcinoma of the thyroi
