Secretory Carcinoma of the Parotid: Making the Correct Diagnosis of a Rare Salivary Gland Carcinoma When Molecular Biology Testing Is Not Available
Figure 1
SC of parotid gland, epithelial neoplasm with a lobular growth pattern, and solid microcystic areas (a-b) [H/E 10X and 40X]. Tubular structures showing abundant, foamy, PAS- and Alcian Blue-positive intraluminal material (c-d). The tumor cells positive for S100 and mammaglobin (e-f), but negative for DOG-1 (g).
