Introduction: Polymorphous low-grade adenocarcinoma (PLGA) is a rare malignant tumor that is found almost exclusively in the minor salivary glands. It frequently occurs in patients between 30 and 70 years old, with a female to male ratio of 2/1. It is usually located in the hard or soft palate. Observation: A 38-year-old female patient presented with a bluish swelling in the right side of the soft palate which had evolved for a year, which was painless and covered with a mucosa of normal appearance. The first diagnosis suggested was pleomorphic adenoma, but the histologic exam following the surgical biopsy revealed a PLGA. Surgical revision of the safety margins was necessary together with mucosal plasty. Discussion: The diagnosis of PLGA is based mainly on clinical and radiological aspects, but a histologic exam is absolutely necessary to confirm it, and for classification of the lesion. Treatment is mainly surgical. The prognosis is good, although the recurrence rate is 17% to 24%. Although seldom, metastases in regional lymph nodes may occur in 9% of cases. Conclusion: PLGA is a non-aggressive tumor whose prognosis depends on several factors including the consultation period. This highlights the importance of early detection. [ABSTRACT FROM AUTHOR]

Objective: To make a list of the epidemiological, etiological, clinical, histological and therapeutic features of necrotizing sialometaplasia (NSM). Material and methods: Analysis of 204 cases from a systematic review of the literature. Results: NSM is an uncommon benign disease of salivary glands. Usually, NSM affects the minor salivary glands of the hard palate. It occurs primarily in adults, NSM is manifested by a sharply demarcated crater-like palatal ulcer. Although the etiology is uncertain, the lesion heals spontaneously. Conclusion: Dental surgeon has to know this lesion because of the risk of histological and clinical confusion with malignant lesions which may lead to mutilating radical treatment.

Acinic cell carcinoma (ACC) is a low grade malignant tumor of the salivary glands. Primary ACC affects most frequently the parotid gland and can rarely arise in the minor salivary glands of the oral cavity, pharynx and larynx. It is extremely rare in the nasal cavity; to our knowledge only 18 cases of primary ACC of the nasal cavity are reported in the English-written literature. Herein we report a case of acinic cell carcinoma of the nasal cavity, describe the clinical, radiological and microscopic features of this uncommon presentation and finally provide a discussion in the light of relevant literature., (Copyright © 2019 Elsevier Masson SAS.
