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. | |||
