“…Associated feeding difficulty may occur as a result of the swelling. This clinical picture often mimics that of a ranula and often is the first clinical diagnosis as in our patient 3 . However, ranula is usually an acquired condition and rarely occurs in neonates with a reported age range of 5 months to 39 years 6 .…”

“…In a review of the literature, only 31 published cases of congenital atresia of the submandibular gland duct were found [3][4][5][6][7][8][9][10][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] , being the majority affecting males with 21 cases, females with only seven cases, and three cases were not informed. The age in the reports ranged from 12 hours to one year and ten months, in agreement with the age range of both cases in this study.…”

Background: Congenital atresia of the submandibular gland duct is a rare condition, originated during the embryogenic process, characterized by swelling in the region of the oral floor. A few cases of congenital atresia of the submandibular gland duct have appeared in the literature and only one reports no surgical intervention to date. Case series: In the present study reports two cases of babies with clinical findings demonstrating swelling well-defined in the region of the oral floor, slightly translucent bluish color, painless to palpation, without finding stones or salivary drainage and apparently with no perforation of the submandibular gland duct. Both patients were kept under observation, later presenting spontaneous regression. Conclusion: This study highlights the importance of conducting a thorough clinical examination in addition to showing that the use of complementary exams may not be essential.

“…Submandibular duct congenital atresia, described for the first time in 1955, is a rare developmental anomaly due to canalization failure of the duct in oral cavity (Mandel and Alfi, 2012). The consequences of this condition are the salivary retention posterior to the imperforate orifice and the presence of cyst-like swelling in the mouth floor (Prosdocimo et al, 2018). Almost all cases observed in newborns, showing male predominance (73%), and unilateral clinical presentation (75%).…”

“…The main differential diagnosis of SMD congenital atresia is oral ranula, and it can be difficult to clinically distinguish between them. However, the histological examination showed lack of epithelial wall, while SMD atresia results in a cystic cavity lined by pseudostratified columnar epithelium with brush borders and thin connective tissue consistent with a dilated duct (Amin and Bailey, 2001; Prosdocimo et al, 2018). The other differential diagnoses include dermal/epidermal inclusion cysts, thyroglossal cysts, bronchogenic cysts, lymphatic and vascular lesions, SG tumors, and sialolithiasis (Pownell et al, 1992; Rosow et al, 2009).…”

Unusual Conditions Impairing Saliva Secretion: Developmental Anomalies of Salivary Glands

et al. 2019

Salivary glands (SG) arise from ectodermal tissue between 6 and 12th weeks of intrauterine life through finely regulated epithelial-mesenchymal interactions. For this reason, different types of structural congenital anomalies, ranging from asymptomatic anatomical variants to alterations associated with syndromic conditions, have been described. Notable glandular parenchyma anomalies are the SG aplasia and the ectopic SG tissue. Major SG aplasia is a developmental anomaly, leading to variable degrees of xerostomia, and oral dryness. Ectopic SG tissue can occur as accessory gland tissue, salivary tissue associated with branchial cleft anomalies, or true heterotopic SG tissue. Among salivary ducts anomalies, congenital atresia is a rare developmental anomaly due to duct canalization failure in oral cavity, lead to salivary retention posterior to the imperforate orifice. Accessory ducts originate from the invagination of the developing duct in two places or from the premature ventral branching of the main duct. Heterotopic ducts may arise from glandular bud positioned in an anomalous site lateral to the stomodeum or from the failure of the intraoral groove development, hindering their proximal canalization. These anomalies require multidisciplinary approach to diagnosis and treatment. While ectopic or accessory SG tissue/ducts often do not require any treatment, patients with SG aplasia could benefit from strategies for restoring SG function. This article attempts to review the literature on SG parenchyma and ducts anomalies in head and neck region providing clinicians with a comprehensive range of clinical phenotypes and possible future applications of bioengineered therapies for next-generation of regenerative medicine.
