A ranula is an extravasated mucocele derived from the sublingual gland which lacks a proper capsule. When a ranula extends through or around the mylohyoidmuscle, it is termed as a plunging ranula and often presents with swelling in the submandibular or cervical region. Here we report a case of a 17 year old girl presenting with a swellingand intermittent pain in the left submandibular region since 6 months.
