Salivary Duct Carcinoma
Salivary duct carcinoma of the parotid with cribriform growth pattern. The small luminal spaces contain basophilic myxoid matrix. In addition to many growth patterns seen with salivary duct carcinoma, there are a number of histologic variants, including sarcomatoid, micropapillary, mucin rich, oncocytic, osteoclast like giant cell, and high grade in-situ variant. Hybrid tumors with multiple histologic types within a given tumor are not uncommon.
