Salivary Mucoceles in Children and Adolescents: A Clinicopathological Study

Abstract

Background: Mucoceles are cavities fi lled with mucous and often occur in the oral mucosa. When they develop in children may cause diagnostic and management concerns. Objectives:The aim of the present study was to examine retrospectively the clinical and pathological features of salivary mucoceles in children and adolescents.Methods: 102 cases of salivary mucoceles in children and adolescents aged from 1 to 17 years were retrieved from our archives and examined for their clinical and histological features and frequency of recurrence. All cases were treated surgically under local anesthesia.Results: Salivary mucoceles most often occurred in patients aged from 11 to 17 years (65,68%) with very weak male predominance (1,04/1). They were located most frequently in lower labial mucosa (87,25%). The incidence of extravasation mucoceles and mucous retention cysts were 99, 01% and 0,98% respectively. Confi rmed history of local trauma and recurrence of the lesions were found 12,74% and 3,92% respectively. Histologically, 77.22% of cases of extravasation mucoceles were well-defi ned cysts surrounded by a capsule of granulation tissue and 22.77% granulation tissue intermixed with mucous. There was not relationship between the duration and histology of the mucous extravasation mucoceles. Conclusions:Possibly, unnoticed local trauma and/or biting habit are the main etiological factors for the most frequent occurrence of extravasation mucoceles in the lower labial mucosa. The occurrence of mucous retention cysts and superfi cial mucoceles in children is very rare.

Papillary synovial metaplasia-like change in oral mucoceles

“…Regarding the size of the lesion, the overall mean size of oral mucoceles in the present review was 1.298 ± 0.79 cm which is slightly higher the mean reported before. [ 6 11 15 ] We further compared the average size in cases showing PSM-like changes (Group II) and cases which did not show this feature (Group I). The size was significantly larger in Group II (1.597 ± 0.96 cm) as compared to Group I (1.173 ± 0.686 cm).…”

Oral Mucocele and its Surgical Approach as Treatment: Case Series

“…2 Local trauma, biting habit, or both are the main etiological factors for extravasation mucocele of the lower labial mucosa. 3 In children, extravasation mucoceles are more common than the retention mucoceles type. 4 There is no clinical difference between retention and extravasation mucoceles.…”

Mucocele oral provocada por mordida acidental: relato de caso

“…É clinicamente caracterizada por uma lesão única de coloração semelhante à mucosa circundante ou levemente azulada, indolor, suave e lisa à palpação, com formato esférico, podendo apresentarse como nódulo flutuante 8 . O diâmetro das mucoceles varia de poucos milímetros até centímetros 9 e sua incidência é difícil de ser estimada devido ao fato de que uma grande percentagem dessas lesões não é encaminhada para exame histopatológico 10 .…”
