There was also erosion through the cribriform plate.
Differential diagnosis: Includes acinic cell carcinoma, mucoepidermoid carcinoma, and low-grade cribriform cystadenocarcinoma of the salivary gland.
It extends from cribriform plate of ethmoid bone to nostrils.
Histologically, it is a basaloid tumor, consisting of ductal epithelial and myoepithelial cells in different configurations, namely, tubular, cribriform, and solid patterns, each of them usually forming a part of a composite tumor.
Papanicolaou stained filters from all samples showed many cohesive three dimensional clusters of uniform cells with balling effects and smooth border (Figures 1a and 1b), cystic spaces, cribriform clusters, branching cylinders and solid clusters with ciliated bronchial cells in the background.
On histopathology, ductal cancer can resemble high-grade prostatic intraepithelial neoplasia (HGPIN), intraductal prostatic carcinoma, the hyperplastic variant of prostate cancer, cribriform Gleason Pattern 4 acinar adenocarcinoma, and metastases (including from the colon and bladder).
