case_images: On histopathological examination (Table 2), half of the cases (five cases) were classical PA, a few seemed to be of the myxoid type (Figure 1), and only one case was cellular. In addition to the myxoid stroma (Figure 1), hyalinized stroma (Figure 2) was also a common finding.
case_images: Duct-like structures filled with eosinophilic material in a hyalinized stroma.

case_images: fig2
case_images: All the cases had ductal structures filled with eosinophilic material (Figure 2) in most of them, with most cases having a swarm bee appearance (Figure 3) of the cells and ducts together, although some areas also revealed a reticular pattern of cellular arrangement (Figure 4). In addition to the myxoid stroma (Figure 1), hyalinized stroma (Figure 2) was also a common finding.

case_images: Plasmacytoid cells (Figure 5) were seen in most of the cases, whereas clear cells (Figure 6) were reported only in a few.

case_images: fig7
case_images: Squamous differentiation was reported only in three cases, with the formation of keratin pearls (Figure 7) in one of them. However, histopathologically, a few cases also resembled schwannoma (Figure 9) and oral squamous cell carcinoma (OSCC) (Figure 7).
