@entity23404 of the major salivary gland is a rare condition. We report on a case of bilateral aplasia of the submandibular glands associated with a @entity1002 . A 62-year-old @entity1 came to our department complaining of a 3-year history of left submandibular swelling. She had no notable family or personal medical history. On physical examination of the head and neck region, a 30 mm, non-tender mass was palpated in the left submandibular area. On imaging examinations including ultrasonography and CT, lack of the right submandibular gland and a left submandibular mass with @entity730 were demonstrated. Fine needle aspiration cytology resulted in blood elements only. Functioning tissue could not be observed in the bilateral submandibular glands on @entity1497 scintigraphy. We performed a left submandibular @entity5 extirpation. Intraoperatively, the left submandibular gland and duct were missing. On pathologic examination, the @entity5 was found to be a @entity2695 . The parotid and sublingual glands were recognized bilaterally on postoperative MRI. Her postoperative condition was satisfactory. This condition may be due to the dysfunction of several factors, such as fibroblast growth factors, related to gland differentiation.
