Figure 1: Grading of mucoepidermoid carcinoma (Armed Forces Institute of Pathology). (Low grade a and b) Large cystic spaces with mucous secretion lined by mucous and epidermoid cells and intermediate cells (a, 400 μ m; b, 200 μ m). (Intermediate grade c and d) c - Well circumscribed lesion with fewer cystic spaces and more solid areas; d - Intermediate grade, predominantly clear, and epidermoid cells (c, 4 mm; d, 200 μ m). (High grade e and f) Solid tumors with the squamoid elements exhibiting anaplasia: Nuclear hyperchromatism, prominent nucleoli, and pleomorphism. Very rare mucous cells seen (e, 50 μ m; f, 70 μ m) (H and E, all)
