Sialolithiasis of minor salivary gland: a challenging diagnostic dilemma.

J Korean Assoc Oral Maxillofac Surg 2021 Apr;47(2):145-148

Department of Oral and Maxillofacial Surgery, School of Dentistry, University of Athens, Athens, Greece.

Minor salivary gland sialolithiasis (MSGS) is a not uncommon oral mucosal disease. Its clinical appearance may mimic a mucocyst or other benign submucosal overgrowth. Stasis of saliva, which accompanies MSGS, usually results in minor salivary gland inflammation, with a chronic sialadenitis appearance. Read More

Magnetic resonance imaging of salivary gland tumours: Key findings for imaging characterisation.

Eur J Radiol 2021 Apr 10;139:109716. Epub 2021 Apr 10.

Department of Experimental and Clinical Biomedical Sciences, Radiodiagnostic Unit n. 2, Careggi University Hospital, Largo Brambilla 3, Florence, 50134, Italy. Electronic address:

Salivary gland tumours are rare, representing only 3% of all head and neck neoplasms, with the parotid gland being the most common site (80 %). The risk of malignancy is inversely proportional to the size of the gland: lesions arising in the sublingual or minor salivary glands are more likely to be malignant, whereas parotid gland neoplasms are mostly benign. Fine needle aspiration cytology and core needle biopsy are considered the most accurate modalities for the diagnosis of a salivary gland neoplasm; however, they are not always conclusive due to procedural sampling errors and for the presence of a cytological / histological overlap between benign and malignant tumours.

[Mucocele of the oral mucous membrane].

Pan Afr Med J 2020 29;35:140. Epub 2020 Apr 29.

Département d'Odontologie Chirurgicale, Faculté de Médecine Dentaire de Rabat, Université Mohammed V, Rabat, Maroc.

Mucoceles of the oral mucous membrane are benign tumoral diseases of the minor salivary glands of the oral mucous membrane. They most commonly occur in the labial mucosa. They can be caused by a break in the epithelium of the gland secreting saliva in the extra-glandular space and forming a pseudo cyst (extravasation mucoceles) or by a block in salivary flow due to an epithelial proliferation of the excretory duct forming salivary cyst (retention cyst).
