All are true about Ranula EXCEPT:

ANSWER: (C) Cyst of submandibular glandREF: With text Ranula:A ranula is a sublingual swelling. Most consist of a mucus filled cyst that lies under the mucosa, just lateral to the frenulum. It is thought to be a retention cyst that arises from the obstruction of one of the several ducts draining the sublingual gland. It presents as an asymptomatic swelling of the floor of the mouth, but occasionally can get so large that it interferes with speech or eating. Treatment consists of uncapping and marsupialising it. Very occasionally, the ranula can penetrate through the mylohyoid muscle and into the neck, when it is known as a plunging ranula. This requires excision, as does a simple ranula if it recurs after uncapping. REF: Textbook of General and Oral Surgery by David Wray, David Stenhouse pahe 121Minor mucous retention cysts develop in the floor of the mouth either from an obstructed minor salivary gland or from the sublingual salivary gland. The term ranula' should be applied only to a mucous extravasation cyst that arises from a sublingual gland. It produces a characteristic translucent swelling that takes on the appearance of a 'frog's belly' (ranula). A ranula can resolve spontaneously, but many also require formal surgical excision of the cyst and the affected sublingual gland. Incision and drainage, however tempting, usually results in recurrence. REF: Bailey & Loves 25th edition page 754
