Mammary analogue secretory carcinoma, abbreviated MASC, is a newly described malignant salivary gland tumour.[1]
General
- Super rare - 21 cases in the world literature as of 2012.[1]
- Has been described in pediatric patient.[2]
- Microscopic appearance similar to secretory breast carcinoma.[3]
Gross
- Usually parotid gland.[3]
- Well-circumscribed.[citation needed]
Microscopic
Features:
- Large cells with abundant cytoplasm.
- Small nuclei.
- +/-Lymphocytic infiltrate.
- Solid and microcystic growth pattern.
DDx:
- Acinic cell carcinoma - very closely mimics.
- Abundant basophilic granular cytoplasm.[1]
- Mucoepidermoid carcinoma.
Images
Stains
Features:[3]
- PAS stain +ve.
- Mucicarmine stain +ve.
IHC
Features:[3]
- S-100 +ve.[1]
- Mammomglobin +ve.
- Vimentin +ve.
Molecular
- t(12;15)(p13;q25).
- Fusion of the genes ETV6 and NTRK3.[1]
Note:
- The translocation seen in congenital-infantile fibrosarcoma.
