UNASSIGNED: A plunging ranula may present initially as an extensive vallecular cyst and correct diagnosis may be reached with the use of ultrasound, fluid aspiration for amylase detection, and MRI imaging.
UNASSIGNED: The ranula is a pseudocyst of the sublingual salivary gland and can be divided into two known subtypes. The simple ranula and plunging ranula. While the simple type can be found in the floor of the mouth, the plunging ranula usually pervades the mylohoid muscle and presents as a cervical swelling. The presented case should outline the difficulties in diagnostic and treatment of an uncommon expression of a mucocele above the mylohoid muscle without presenting either a cervical or an intraoral swelling, only extending towards the vallecula. We present a previously unreported clinical manifestation of a ranula of an 18-year old male, which extends posteriorly, remaining confined in the supramylohyoid muscle space. The cystic lesion protrudes in the oropharynx, and clinically appears as an extensive vallecular cyst. On magnetic resonance imaging the initial suspected diagnosis of a vallecular cyst was changed to the final diagnosis of a plunging ranula. The marsupialization of the cyst sac was performed. Outpatient follow-up revealed a persisting ostium, indicating a continuous extravasation of the sublingual gland. The present case report describes an unusual clinical presentation of a plunging ranula, remaining above the mylohyoid muscle and protruding into the oropharynx, misdirecting to the first suspected diagnosis of a vallecular cyst. The case highlights the useful contribution of the MRI imaging for differential diagnoses and the need for criteria to indicate further investigations.

Mucocele is a common salivary gland lesion which most commonly occurs on the lower lip. Several treatment options are available for its elimination with surgery being the most commonly used method. A 49-year-old male presented with a small, round, painless swelling on the left buccal mucosa since 6 months. A clinical diagnosis of oral mucocele on the left buccal mucosa was made. Due to the inaccessibility of the posterior buccal mucosa region, sclerotherapy with sodium tetradecyl sulfate was planned. The patient did not show any obvious reduction in the size of swelling after 1 week of therapy. Therefore, a second injection was planned. After another 1 week, complete resolution of the lesion was seen with no complications. No recurrence of the lesion has been seen after 6 months of therapy. Due to the various drawbacks of surgical management of oral mucocele, sclerotherapy can be an effective alternative.

The purpose of this paper is to discuss a rare case of bilateral congenital mucous extravasation phenomenon on buccal mucosa near commissure of mouth. The lesions were noted at birth, subsequently enlarged to interfere with feeding. The lesion frequently ruptured, regressed, and again enlarged to interfere with normal function. The lesions were surgically removed under general anesthesia at 11 months of age and the diagnosis was confirmed by histopathological examination. Postoperative follow-up after 14 months showed no recurrence.

OBJECTIVE: Mucus retention cyst of the hard palate may result from obstruction of the ducts of the minor salivary glands, and it was defined as a mucocele. Although, the disease is not common in the hard palate, it was previously reported by many authors in the soft palate. The aim of our study was to present pediatric patients who were diagnosed to have mucocele of the hard palate, and to evaluate the outcome of the surgical excision of this lesion.
METHODS: This is a case series study included 8 pediatric patients who presented with cystic lesions on the hard palate which were removed surgically, and were diagnosed as mucoceles. Preoperative data, surgical procedures, and postoperative outcome were presented. Follow up of patients was performed for at least one year.
RESULTS: The swelling was detected as a single isolated lesion, on the side of the hard palate, covered with healthy mucosa, not tender, oval or round in shape, and measuring 0.4 to 1.7cm in its greatest dimension. Computed tomography showed a well defined cavity which was not invading the bone, and not disrupting the muscles of the palate. Histopathological examination confirmed that the lesion was a cavity that is lined with an epithelial layer with pseudoepitheliomatous hyperplasia. No patients developed intraoperative or postoperative complications, and no recurrence was detected in any patient.
CONCLUSIONS: Oral mucoceles can develop on the hard palate of the children, the lesions are mucus retention cysts. Complete surgical removal of the lesions with their cystic wall is a good treatment options, it carries no risk of recurrence.

BACKGROUND: Oral mucocele is the most common benign minor (accessory) salivary gland lesion, caused due to mechanical trauma to the excretory duct of the gland. Clinically they are characterized by single or multiple, soft, fluctuant nodule, ranging from the normal color of the oral mucosa to deep blue. It affects at any age and is equally present in both sexes with highest incidence in second decade of life. They are classified as extravasation or retention type.
OBJECTIVE: To analyze the data between 2010 and 2011 of, clinically and histopathologically diagnosed 58 oral mucoceles for age, gender, type, site, color, cause, symptoms and dimension.
RESULTS: Oral mucoceles were highly prevalent in the age group of 15-24 years, were seen in 51.72% of males and 48.28% of females, with a ratio of 1.07:1. The extravasation type (84.48%) was more common than the retention type (15.52%). The most common affected site was lower lip (36.20%) followed by ventral surface of the tongue (25.86%). The lowest frequency was observed in floor of mouth, upper lip and palate. The maximum numbers of mucoceles were asymptomatic (58.62%), and the color of the overlying mucosa had color of adjacent normal mucosa (48.28%). It was also observed that most of the mucoceles had diameter ranging from 5 to 14 mm. The causative factors of the lesion were lip biting (22.41%), trauma (5.18%) and numerous lesions (72.41%).
CONCLUSIONS: Oral Mucoceles are frequently seen in an oral medicine service, mainly affecting young people and lower lip, measuring around 5 to 14 mm and the extravasation type being the most common.

Oral mucoceles are small-size, benign minor salivary gland pathologies. The most frequent localizations of these lesions are the lower lip mucosa. However, in some cases, they grow to an unusual size and hinder the preliminary diagnosis of mucocele. The purpose of this article is to report a case of a large oral mucocele with a diameter of 3.5 cm on the buccal mucosa of a 43-years-old male patient. The surgical procedure was carried out for a complete removal of the lesion.
