Right Parotid Lesion, Core Biopsy:
    - SECRETORY CARCINOMA of the salivary gland, see comment.
Comment:
Secretory carcinoma of the salivary gland was previously known as "mammary analogue secretory carcinoma" (MASC).
The tumour stains as follows:
POSITIVE: CK7 (strong, diffuse), mammaglobin (strong, diffuse), S100 (moderate, patchy), mucin (focal).
NEGATIVE: p63.
NTRK testing was ordered; the results will be reported in an addendum.
</pre>
===Micro===
The sections show a cohesive tumor with moderate amphophilic cytoplasm and vacuolation. The vacuolation is focally prominent. Nucleoli are inconspicuous. Poorly formed glands are present. Keratinization is absent.
