A Case of Large Pseudocyst Originating from the Submandibular Gland Presented with a Systematic Review

The majority of mucous cysts originate from the sublingual gland. Mucoceles originating from the submandibular glands are extremely rare. We report the case of a 24-year-old girl with submandibular gland mucocele. Magnetic resonance imaging (MRI) revealed cystic lesions in close proximity to the submandibular gland without tail sign. The cyst with submandibular gland was successfully removed through a cervical approach without complications. The pathologic and intraoperative examination confirmed the pseudocyst originating from the submandibular gland. The patient has no evidence of recurrence. We review previous cases of mucoceles originating from the submandibular gland.
