“…They might originate from ectopic embryonic epithelial cells derived from ectoderm or from remanent vomero-nasal organs [5]. The heterotopic salivary glands are rarely the site of diseases [11].…”

Pleomorphic adenomas represent 80% of the salivary gland’s benign tumors. They are most often found in the parotid gland or in the submandibular gland. Pleomorphic adenomas of the nasal cavity are rare, with less than fifty cases reported to date. There are no treatment or follow up guidelines. The purpose of this article is to review the cases already described in the literature and to share our clinical experience. We describe the case of a 38-year-old woman with a history of a slow growing intranasal tumor with recurrent epistaxis, obstruction, and aesthetic deformation. The pre-operative assessment suggested a benign tumor, but the biopsies were inconclusive. The decision was taken to perform an open rhinoplasty to have an en bloc resection with margins control. The diagnosis of pleomorphic adenoma was established on the excised tumor. There were no post-operative complications. The early follow-up showed no signs of recurrence. We decided to closely follow the patient with frequent clinical examinations and yearly enhanced-MRIs for at least five years due to the recurrence and malignant transformation risks.

“…In both entities, low prevalence results in few searches, which contributes to their relative obscurity. Of the published works, some refer to findings during anatomical dissection ( 14 , 15 ), others to the presence of pathology in those areas: obstructive alterations such as sialolithiasis ( 11 , 16 , 17 ) or even tumors, for example the presence of a mixed tumor ( 2 , 6 ).…”

“…Any salivary tissue (except the major and minor salivary glands) found in the oral cavity, pharynx or upper airway is called heterotopic, most frequently seen in the neck and jaw ( 4 , 5 ). Heterotopic tissue, found in an incorrect anatomical location, is due to embryological aberrations ( 6 ). It is important to distinguish it from accessory glandular tissue, regarding which Batsakis ( 4 ) postulates that the appearance of these accessory glands is due to the detachment of glandular tissue along the course of the major salivary duct.…”

Accessory submaxillary gland: Two new case reports and a literature review

et al. 2020

View full text Add to dashboard Cite

Background The accessory submaxillary gland is a very uncommon anatomical variant, and incidence in the general population has not yet been quantified. The presence of pathology in these glands is rarer still, thus often going unnoticed. Material and Methods We describe two accessory submaxillary gland cases, one asymptomatic and the other with chronic sialadenitis in the main and accessory gland caused by sialolithiasis. Although our diagnosis was by computerized tomography, magnetic resonance sialography is helpful to understand and describe this entity with greater precision. Results The first case report is an incidental finding and no intervention was required. However, case report number two had clinical symptoms and required a first intervention in which the main submaxillary gland was resected, and a second intervention in which the accessory submaxillary gland was removed. Both patients are asymptomatic to date. Conclusions Awareness of the possible presence of accessory submaxillary glands and of potential variations of the excretory ducts is useful in diagnosis, as well as leading to more precise treatment for salivary pathology, and allowing surgeons to avoid complications or injuries during surgery. Key words: Accesory, submaxillary gland, submandibular gland, salivary gland, sialolithiasis, head and neck pathology.

“…These accessory (or duplicate) submandibular glands have most commonly been identified in the course of an evaluation for symptoms of sialadenitis prompting sialography that demonstrates the presence of a second duct [2 – 4] . Reports have also described a pleomorphic adenoma as the initial cause of submandibular swelling leading to identification of submandibular accessory glands [5 , 6] . The majority of cases of duplicate submandibular glands we identified through literature review were evaluated with conventional sialography, with only 2 reported cases evaluated concurrently with MR sialography [3 , 7 , 8] .…”
