Abstract
Palisading adenocarcinoma is a morphologically distinct salivary gland neoplasm that has been recently described with predilection to the sublingual gland. We report our experience with this neoplasm to corroborate and enrich the literature and further clarify its phenotype.

Diagn Cytopathol 2024. [PMID: 39051522 DOI: 10.1002/dc.25385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2024] [Revised: 07/10/2024] [Accepted: 07/11/2024] [Indexed: 07/27/2024]
Abstract
Here, we report the first cytology findings of the newly characterized entity, palisading adenocarcinoma of the salivary gland, diagnosed in the sublingual gland of a 61-year-old female. The liquid-based cytology showed a moderately cellular aspirate containing three-dimensional clusters and trabeculae of tumor cells of various sizes. The cells had dark ovoid nuclei, finely granular chromatin, inconspicuous to punctate nucleoli, and ample cyanophilic cytoplasm with indistinct cell borders. In conventional smears, the cells displayed frequent crush artifacts and anisonucleosis resembling endocrine-type atypia. The background was clean, devoid of secretions, and contained singly dispersed tumor cells with stripped nuclei. Interestingly, concentrically laminated globules of extracellular matrix surrounded by the tumor cells were identified. Mitotic figures and tumor necrotic debris were absent. The cytologic findings correlated with the histologic findings of the excision specimen. The cytologic differential diagnosis and tumor grading of palisading adenocarcinoma were briefly discussed.

Abstract
In 2022, the 5th edition of the WHO classification of Head and Neck tumors was published online. In the salivary gland chapter, a new benign entity, the keratocystoma, was introduced. The sclerosing polycystic adenosis has been recognized as tumoral and is now termed sclerosing polycystic adenoma. The striated duct adenoma now has its own dedicated chapter. Additionally, a new variant of pleomorphic adenoma, termed "canalicular adenoma-like," has been incorporated. Regarding malignant tumors of the salivary glands, significant doubts now exist regarding the actual existence of oncocytic carcinoma, which has been reclassified among emerging entities. Two new malignant entities have also emerged: microsecretory adenocarcinoma and microcystic sclerosing adenocarcinoma. Finally, primary mucinous adenocarcinoma of the salivary glands has been acknowledged as a distinct entity.

Abstract
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.
