What are lymphatic cysts?
Lymphatic cysts, or lymphatic malformations, are non-cancerous masses that form from the abnormal development of lymphatic vessels. The lymphatic system is a critical part of the immune system, composed of a network of vessels that transport a clear fluid called lymph throughout the body. When these vessels do not form correctly, it can create a blockage, causing lymph fluid to pool and form a cyst.
There are three primary types of lymphatic malformations, often differentiated by the size of the fluid-filled cysts they contain:
- Macrocystic: Characterized by large cysts, often over 2 cm in diameter. These are also known as cystic hygromas and are frequently found in the neck or armpit areas.
- Microcystic: Consisting of many small, fluid-filled cysts. These can appear as a collection of raised, blister-like sacs on the skin, known as lymphatic blebs.
- Mixed: A combination of both microcystic and macrocystic elements.
While most lymphatic malformations are present at birth (congenital), some may not become apparent until later in life. The exact cause is not fully understood, but it is believed to be linked to abnormal embryonic development of the lymphatic system.
Medical treatments for lymphatic cysts
Seeking professional medical advice is the most important step when considering how to get rid of a lymphatic cyst. A healthcare provider, often a specialist like an interventional radiologist or a vascular anomaly expert, will assess the cyst and recommend the most appropriate course of action.
Sclerotherapy (injection therapy)
Sclerotherapy is a highly effective treatment, particularly for macrocystic lymphatic malformations. The procedure involves injecting a sclerosing (irritating) agent directly into the cyst. The agent causes the inner walls of the cyst to become inflamed and collapse, leading to scarring that prevents fluid from collecting again. Ultrasound or other imaging techniques are used to precisely guide the needle during the injection. Multiple sessions may be required for complete resolution.
Surgical excision
Surgical removal is an option for certain types of lymphatic cysts, especially smaller, well-defined ones located in easily accessible areas. While surgery can remove the cyst entirely, it can be challenging for malformations that are deeply embedded or tangled around vital structures like nerves. In some cases, a small amount of residual tissue may be left behind to avoid damaging healthy tissue, which could lead to a recurrence of the cyst. Newer, minimally invasive surgical techniques can reduce the size of the incision and recovery time.
Laser therapy
Laser therapy is primarily used for superficial lymphatic cysts that are visible on the skin. This treatment is often not curative but can significantly improve the appearance of problematic areas, such as skin-level lymphatic blebs that may bleed or ooze fluid. It is a less invasive option than traditional surgery for these specific presentations.
Drug therapy
Recent advancements have introduced drug therapies, such as sirolimus, for treating certain complex or widespread lymphatic malformations. Sirolimus is an immunosuppressant drug that has been shown to effectively reduce the size of lymphatic lesions by affecting cell growth and division. This treatment is typically managed by a hematologist or oncologist and requires careful monitoring.
A comparative look at treatment options
| Treatment Method | Best For | Procedure | Potential Side Effects | Recurrence Rate | Recovery Time |
|---|---|---|---|---|---|
| Sclerotherapy | Macrocystic lesions | Minimally invasive injection | Pain, swelling, redness | Moderate | Days to weeks |
| Surgical Excision | Small, localized cysts | Surgical removal | Infection, scarring, nerve damage | Low (if fully removed) | Weeks |
| Laser Therapy | Superficial, skin-level cysts | Uses focused light | Skin discoloration, scarring | High (palliative) | Days |
| Drug Therapy (Sirolimus) | Complex/widespread lesions | Oral medication | Blood count changes, infections | Varies | Ongoing |
Can home remedies help with a lymphatic cyst?
Home remedies are not a substitute for medical treatment and will not eliminate a lymphatic cyst. However, some measures may help manage associated symptoms or discomfort, especially for small, stable cysts. Warm compresses can sometimes reduce swelling and improve comfort. For superficial skin issues, proper skin care and hydration are crucial to prevent infection. It is important to emphasize that you should never attempt to drain a lymphatic cyst at home, as this can lead to serious infection.
What to expect during recovery
Recovery from a medical procedure to remove a lymphatic cyst depends on the treatment method used. For sclerotherapy, patients might experience some pain, swelling, and bruising in the treated area, which typically subsides within a few days to weeks. Surgical recovery involves managing the incision site, with full healing taking several weeks. For extensive or complex malformations, a longer hospital stay and post-operative care may be necessary. For ongoing drug therapy, regular monitoring and follow-up appointments are essential.
The importance of follow-up care
Due to the nature of lymphatic malformations, there is a risk of recurrence, particularly if the entire lesion cannot be safely removed. Regular follow-up appointments with your healthcare provider are crucial for monitoring the area and addressing any signs of regrowth. Continued management, especially for larger or more complex malformations, is key to long-term success and symptom control.

Conclusion
Getting rid of a lymphatic cyst is a medical process that requires a personalized approach based on the specific characteristics of the malformation. While options range from minimally invasive sclerotherapy to surgical removal and systemic drug therapy, the first and most critical step is a proper medical evaluation. Self-treatment should be avoided due to the risks of complications. By working with a knowledgeable healthcare team, patients can find the most effective strategy to manage and resolve their lymphatic cyst, leading to a better quality of life and reduced symptoms.
