A palisading adenocarcinoma arising in the left submandibular salivary gland in a 65-year old woman is presented here. This tumor has been identified only very recently and its recognition as a true entity in the list of salivary gland tumors is still pending. Its distinct clinical-pathological context includes a predilection for women, sublingual or submandibular gland involvement, low-grade cytology with pseudo-neuroendocrine features, and sharp immunohistochemical expression.
Keywords: Histology; Immunohistochemistry; Palisading adenocarcinoma; Salivary gland; Submandibular gland.
