Acinic cell carcinoma, papillary-cystic variant of the parotid gland: A case report with review of literature

Acinic cell carcinoma (ACC) is a rare, slow growing, low grade neoplasm of salivary glands and some extra salivary sites. ACC-papillary cystic variant is histologically composed of tumor with papillary and cystic growth patterns, with varying proportions of one or more of 5 cell types which include “hobnail” acinar, intercalated, vacuolated, non-specific glandular and clear cells. The clinical picture is not specific and diagnosis is based on the histopathologic examination. The present case describes ACC-papillary cystic variant and discusses the myriad architectural patterns exhibited by it.
