An 11-year-old female patient complained of "a blister in the mouth." Intraoral examination evidenced a bullous lesion in the left mouth floor measuring approximately 4 cm with exophytic growing, bluish coloration, defined limits, soft consistency, smooth surface, and 5 days of evolution. Clinical diagnosis was ranula. Micromarsupialization was performed after infiltrative anesthesia, and surgical knots were made far from the mucosa by the interposition of a hemostatic clamp, forming fistulas originating from the epithelization around the thread, allowing salivary flow. In the transoperative period, there was immediate drainage of part of the content retained within the lesion, reducing its initial volume. Surgical knots were removed after 7 days, and the patient was followed up for 3 months. The lesion regressed entirely without signals of recurrence, ruling out the need of excision. Therefore, micromarsupialization stands as a conservative therapy for the treatment of ranulas and mucoceles of significant size.

Objective Biological behavior of oral squamous cell carcinoma (OSCC) in young patients is controversial. Therefore, this study compared prognostic factors of OSCC between young and older patients, through a systemic review. Study Design Electronic search in the databases Pubmed/Scopus/Ovid/Proquest/Cochrane Library/Web of Science/Lilacs was performed until April 2018, without filters by language or year of publication. Only cohort studies were included and evaluated by Newcastle-Ottawa scale for risk of bias. Analysis of titles and abstracts was made by 2 calibrated researchers (kappa = 0.94). Results A total of 5370 articles were reviewed, and 10 of the most relevant articles that are suitable to the criteria were selected. All included studies had a low risk of bias. Independent of age group, male was more affected, and tongue was anatomic site more frequent. Main risk factors were smoking and alcoholism in both age groups. Most patients in both age groups were diagnosed in early clinical stages (I/II). Regarding to histologic grading, majority of OSCC was classified as moderately differentiated in both age groups. Lower survival was observed in older patients. Conclusions Among all prognostic factors evaluated, survival showed difference in age groups, suggesting, then, that OSCC in older patients could exhibit more aggressive biologic behavior.
