Persistent Swelling in the Submandibular Gland: Causes and Concerns

Lymphadenopathy

Hello! For the past year, I have had a lump in my submandibular gland that often becomes inflamed and swollen.
I had a CT scan at Chung Shan Medical University in February, which indicated no tumors.
They advised me to return if there were any issues, but over the past few months, it continues to swell and become inflamed, and the lump has not diminished.
When I palpate it, it feels about 2 to 3 centimeters in size.
I'm quite worried! It has not increased in size over time.
What could this phenomenon be?

Hello, Ms.
Hsin.
Based on your description, it is most likely that you are experiencing cervical lymphadenopathy or swelling of the submandibular salivary gland.
If a CT scan has already been performed and confirmed that there are no stones, tumors, or suspicious lymph nodes, it is usually indicative of sialadenitis (inflammation of the salivary gland).
It is advisable to increase your water intake and consider the use of antibiotics as needed.
If a definitive diagnosis is desired, surgical removal may be considered depending on the situation, followed by pathological examination.
It is recommended to seek a medical consultation for a thorough examination.
Wishing you peace and good health.

Sincerely,
Dr.

More Info

Persistent swelling in the submandibular gland can be concerning, especially when accompanied by inflammation and discomfort. The submandibular glands are one of the major salivary glands located beneath the jaw, and they play a crucial role in saliva production. When these glands become swollen, it can be due to a variety of causes, some of which may require medical attention.

One common cause of swelling in the submandibular gland is sialadenitis, which is an inflammation of the salivary gland. This condition can occur due to a bacterial or viral infection, often resulting from a blockage in the salivary duct. Blockages can be caused by salivary stones (sialolithiasis), which are hard deposits that form in the gland and can obstruct the flow of saliva. When saliva cannot flow properly, it can lead to swelling, pain, and sometimes infection.

Another potential cause of persistent swelling could be chronic sialadenitis, which is a long-term inflammation of the gland. This condition might not always be associated with infection but can result from repeated episodes of acute sialadenitis or other underlying issues.
In some cases, autoimmune conditions such as Sjögren's syndrome can lead to swelling of the salivary glands. This syndrome is characterized by the immune system attacking the glands that produce saliva and tears, leading to dryness and swelling.

While your CT scan in February indicated no tumors, it is essential to continue monitoring the situation. The fact that the swelling has not increased in size is a positive sign, but persistent swelling and inflammation warrant further investigation. It is advisable to follow up with your healthcare provider, especially if you experience additional symptoms such as pain, fever, or difficulty swallowing. Your doctor may recommend further imaging studies, such as an ultrasound, or even a biopsy if there are concerns about the nature of the swelling.

In the meantime, there are some self-care measures you can take to alleviate discomfort. Staying well-hydrated can help promote saliva flow, and massaging the area gently may also assist in relieving some of the swelling. Warm compresses applied to the affected area can provide comfort and may help reduce inflammation.

If you notice any changes in the swelling, such as an increase in size, changes in color, or the development of new symptoms, it is crucial to seek medical attention promptly. Persistent swelling in the submandibular gland can sometimes indicate underlying issues that need to be addressed, so maintaining open communication with your healthcare provider is essential for your peace of mind and overall health.
