Microscopic examination of the sections from salivary gland revealed partially circumscribed neoplasm (Figure 1) composed of numerous duct like structures and cystic spaces lined by flat to cuboidal epithelium and filled with keratin flakes intricately mixed with lymphoid stroma showing follicular formation in areas (Figure 2).

Duct like space were lined by outer basaloid cells and inner mature sebaceous cells were present (Figure 3) focal squamous and mucinous metaplasia of lining epithelium was also seen along with areas of fibrosis and calcification.

In one area neoplasm was seen to arise from lining epithelium of duct like spaces composed of polygonal cells with moderate cytoplasm and hyperchromatic pleomorphic nuclei, arranged in sheets, nests and group foci of keratinsation seen in between cell groups (Figure 4).
