Saliva extravasation from the sublingual gland causes ductal lesion or obstruction and results in the formation of a ranula. It spreads through or behind the mylohyoid muscle situated on the neck. Most frequently it is located in the submandibular or submental region. The diagnosis of plunging ranula is simple if the signs of ranula are present in the intraoral cavity, whereas in case of a ranula localized on the neck definite diagnosis is made by histologic analysis of the pseudocyst that has been surgically excised in toto. Cases are presented of both types of plunging ranula treated by various surgical approaches. Plunging ranula in the submental region was treated by transoral approach, marsupialization and aspiration of the content, whereas the ranula in the submandibular region was treated by exterior cervical approach. In both cases, sublingual gland was removed. During the 3.5-year follow-up, neither recurrence of the disease in the neck area nor the occurrence of simple ranula in the intraoral region was observed.

Plunging ranula is the extravasation of saliva from the sublingual gland caused by trauma or obstruction of the duct, extending through a defect in the mylohyoid muscle into the submandibular gland. The prevalence of plunging ranula is estimated to be about 2.6 per 100,000 cases with mostly unilateral lesions.

Plunging ranulas are rare retention pseudocysts of the major salivary glands, most often of the sublingual gland, and usually occur in individuals from the first to the sixth decade of life with female predominance. Given their similar location and physical and imaging characteristics to thyroglossal cysts, distinguishing the two lesions is often a differential diagnostic dilemma even for the experienced physician. This case report presents a 42-year-old man for whom a preliminary diagnosis of a thyroglossal duct cyst was made based on a physical examination.

Synovial sarcomas are uncommon and highly aggressive sarcomas. Typically, they start in the soft tissues of the extremities, although they may develop in the head and neck region in rare cases. When they do, they usually present with localized symptoms in the affected area.

- A plunging ranula, a type of sublingual salivary gland cyst, can initially be mistaken for a vallecular cyst, but ultrasound and MRI are important for accurate diagnosis.* -
- The case presented involves an 18-year-old male with a rare form of plunging ranula that extends above the mylohyoid muscle into the oropharynx without a typical cervical swelling.* -
- The report emphasizes the importance of using MRI for distinguishing between diagnoses and highlights the need for establishing guidelines for further investigations in such atypical cases.*

Unlabelled: The Plunging or cervical ranula is a mucus pseudocyst extension of the sublingual gland that is located below the mylohyoid muscle. In infants, owing to small sublingual and cervical space, clinically large cervical ranulas can lead to a significant impact on swallowing, crying, and even breathing (Carlini et al. in Pediatr Rep 8(4):6576, 2016; Övet et al.
