}} A ranula is a type of mucocelefound on the floor of the mouth. Ranulas present as a swellingof connective tissueconsisting of collected mucinfrom a ruptured salivary glandduct, which is usually caused by local trauma.

The latin rana refers to frog, and a ranula is so named because its appearance is sometimes described as a frog's underbelly.

Locations

The gland most likely to cause a ranula is the sublingual gland. Nonetheless, the submandibular glandand minor salivary glands may be involved.

Appearance

A ranula is a fluctuant swelling with a bluish translucent color.

Though normally above the mylohyoid muscle, if found deeper in the floor of the mouth, it can appear to have a normal color. A ranula below the mylohyoid muscle is referred to as a "plunging or cervical ranula", and produces swelling of the neck with or without swelling in the floor of the mouth.

The size of ranulas are usually larger than mucoceles with several centimeters in diameter. As a result, the tongue may be elevated. As with mucoceles, ranulas may have recurrent swelling with occasional rupturing of its contents.

Histology

Microscopically, ranulas appear similar to mucoceles. Thus, granulation tissuesurrounding mucin is present.

Treatment

Treatment of ranulas involves excisionof the top of the lesion in a procedure known as "marsupialization". Recurrence may occur if the sublingual gland or other gland causing the ranula is not removed.
