Nces in current years, and they’ve allowed for better classification with the previously heterogenous categories of adenocarcinoma, NOS and oncocytic carcinoma, and have led for the discovery of novel tumor types such as secretory carcinoma (mammary analogue) and microsecretory adenocarcinoma. Extra neoplastic entities will practically certainly be defined as characteristic molecular alterations are discovered in tumors with reproducible morphologies. Nevertheless, the synthesis of morphological patterns andHead and Neck Pathology (2022) 16:40Fig. 4 Microsecretory adenocarcinoma (MSA). MSA is little tubules and microcysts lined by flat intercalated ductlike cells, and containing abundant basophilic luminal secretions (Fig. 4A, B). Tumor cells show diffuse positivity for p63 (Fig. 4C), S100 protein (Fig. 4D)and SOX10 (Fig. 4E). Next generation sequencing of MSA shows a recurrent MEF2C::SS18 gene fusion (Fig. 4F).

SMAs consist of smaller infiltrative cords and nests embedded in thick fibrous or desmoplastic stroma (Fig. 5A). Perineural invasion is prevalent (Fig. 5B). (courtesy of Dr. Abbas Agaimy)Fig. six Intraductal carcinoma (IC). IC generally shows an intercalated duct phenotype demonstrating SOX10 positivity of luminal cells (Fig. 6A, B), though a subset of IC shows apocrine morphology supported by androgen receptor positivity (Fig. 6C, D)molecular alterations driving them is rarely straightforward. In addition to the difficulties discussed above, concerns stay concerning the classification of neoplasms with morphologies matching identified forms however the tumors lacking the recognized molecular alterations. Is mucoepidermoid carcinoma with no MAML2 gene rearrangement stilla mucoepidermoid carcinoma or possibly a convincing mimic Is really a secretory carcinoma with an atypical VIM::RET fusion nevertheless a secretory carcinoma As much more molecular and clinical data accumulates about these tumors, such queries may perhaps be answered as well as the tumor classification adjusted accordingly in future editions.Head and Neck Pathology (2022) 16:40Fig. 7 Polymorphous adenocarcinoma, cribriform subtype (CASG). CASG is characterized by a multinodular growth pattern separated by fibrous septa, with predominant glomeruloid, cribriform and microcystic architecture (Fig. 7A, B).
