(a) Chronic sialadenitis: hypocellular smear with background lymphocytes and small cohesive group of ductal cells (Giemsa ×400). (b) Chronic sialadenitis: periductal fibrosis accompanied by chronic inflammatory cell infiltrate and acinar atrophy (H&E ×400). (c) Pleomorphic adenoma: the matrix is in slight magenta colour with myoepithelial cells present individually and in clusters (Giemsa ×400). (d) Pleomorphic adenoma: ductal structures are surrounded by abluminal myoepithelial cells and hyalinized, myxoid, and chondromyxoid stroma (H&E ×400). (e) Monomorphic adenoma: fragmented groups of haphazard arranged cells as squamous morules and intercellular matrix droplets (Giemsa ×400). (f) Monomorphic adenoma: aggregates of tumor cells were arranged as an inner layer of luminal epithelial cells and surrounded by an outer layer of myoepithelial cells (H&E ×400).
