Differential Diagnosis
ОглавлениеImmunohistochemical markers are crucial to the diagnosis of this entity. The main differential diagnosis is with neuroendocrine carcinoma and the solid form of adenoid cystic carcinoma. Positive epithelial markers exclude lymphoma, melanoma, and primitive neuroectodermal tumour (PNET). Nasopharyngeal carcinoma and oropharyngeal carcinoma associated with high-risk HPV are also included in the differential diagnosis. These entities can be morphologically indistinguishable, so that clinical and radiographic correlation is essential for the diagnosis.
