Blood clot in the buttock?
In December 2018, a blood clot was discovered in the buttock, but the cause was unknown.
The doctor recommended allowing it to be absorbed and resolved on its own.
However, later on, a wound developed in the buttock, causing blood to spray out.
In September 2019, surgery was performed, and the biopsy results revealed the presence of a sebaceous cyst.
Recently, there has been pain in the area near the surgical site, and an ultrasound showed a 4 cm blood clot.
However, I have no history of trauma.
I would like to ask the doctor what conditions could lead to the formation of a blood clot in the buttock without any trauma, as this issue has been troubling me for over a year.

Hello! It is most likely an inflamed and ruptured sebaceous cyst.
Normally, a healthy young person would not experience unexplained bleeding or hematoma in the buttocks unless you are taking anticoagulants or have a congenital bleeding disorder.
It is advisable to seek prompt medical attention! Take care! Changhua Hospital cares about you!

Understanding non-traumatic blood clots, especially in the buttocks, can be a complex issue that raises several concerns. Blood clots can form for various reasons, and while trauma is a common cause, there are several non-traumatic factors that can lead to the development of blood clots in the body, including the buttocks.
One of the primary causes of non-traumatic blood clots is the presence of underlying medical conditions. Conditions such as deep vein thrombosis (DVT) can occur in the absence of any noticeable injury. DVT is characterized by the formation of a blood clot in a deep vein, often in the legs, but it can also occur in other areas, including the buttocks. Risk factors for DVT include prolonged immobility, such as sitting for long periods during travel or after surgery, obesity, certain genetic conditions that affect blood clotting, and the use of hormonal medications like birth control pills.
In your case, the history of a lipoma (a benign tumor made of fat tissue) that was found during surgery could also be relevant. If the lipoma became inflamed or infected, it could potentially lead to localized swelling and the formation of a hematoma (a collection of blood outside of blood vessels) in the surrounding tissues. This could explain the presence of a blood clot without any external trauma. Additionally, if the lipoma was pressing on nearby blood vessels, it could have disrupted normal blood flow, contributing to clot formation.
Another important consideration is the use of anticoagulant medications or any conditions that predispose you to bleeding or clotting disorders. If you are taking medications that affect blood clotting, such as anticoagulants or antiplatelet drugs, this could increase your risk of developing blood clots. Similarly, if you have a family history of clotting disorders or have been diagnosed with conditions such as antiphospholipid syndrome or Factor V Leiden mutation, these could also contribute to the formation of blood clots.
In terms of management, it is crucial to follow up with your healthcare provider, especially since you have experienced recurring issues with blood clots and pain in the area. Imaging studies, such as ultrasounds, can help monitor the size and nature of the blood clot and determine if any intervention is necessary. If the clot is symptomatic or increasing in size, your doctor may recommend treatments ranging from observation to surgical intervention, depending on the specific circumstances.
Additionally, lifestyle modifications can play a significant role in managing your risk for blood clots. Regular physical activity, maintaining a healthy weight, and avoiding prolonged periods of immobility can help reduce the risk of clot formation. If you have any underlying conditions, managing those effectively with the help of your healthcare provider is also essential.
In summary, non-traumatic blood clots in the buttocks can arise from various factors, including underlying medical conditions, previous surgeries, and lifestyle factors. It is essential to work closely with your healthcare provider to monitor your condition, explore potential underlying causes, and determine the best course of action for your health. If you have ongoing concerns or new symptoms, do not hesitate to seek medical advice promptly.
