Subcutaneous Cysts: Symptoms, Causes, and Solutions

Q: Subcutaneous Cysts: Symptoms, Causes, and Solutions

Hello： Based on your description, the lump can be squeezed to release a non-sticky white pasty secretion, and it is mostly located in the groin and underarm areas. <br>From the information provided, it is preliminarily judged to be a sebaceous cyst, somewhat similar to acne. <br>

Is it a subcutaneous cyst?

About a year ago, I noticed some symptoms where I found lumps in certain areas of my body.
The lumps themselves are not painful, but if I apply pressure, a white, paste-like, but non-sticky secretion can be expelled.
Once expelled, the lumps are no longer palpable.
However, there have been instances where they disappear after some time.
Initially, I discovered them under the skin near the genital area and groin.
After expelling the secretion, I could no longer feel the lumps.
Later, I also had them on the inner thigh and on the flesh of my buttocks.
The lumps on my thigh eventually became unnoticeable, while the ones on my buttocks became slightly swollen after expulsion but subsided after a while.
Recently, I found one in my right armpit.
After expelling the secretion, I noticed a lump reappearing in the same location after some time.
Although I can expel some secretion, I cannot completely empty it.
Could this be a sebaceous cyst? Or could it be related to obesity? Are there any self-management methods I can try?

The term "subcutaneous cyst" is a broader term, and generally, it tends to develop more easily in individuals with oily skin.
It is advisable to have it evaluated and treated by a dermatologist or a general surgeon.
Wishing you well.

More Info

Subcutaneous cysts, often referred to as epidermoid cysts or sebaceous cysts, are common benign growths that can occur in various parts of the body. They are typically characterized by the presence of a firm lump beneath the skin, which may or may not be painful. The symptoms you describe—hard lumps that can be squeezed to release a white, paste-like substance—are indeed indicative of subcutaneous cysts.

Symptoms and Characteristics
1. Firmness: The cysts are usually firm to the touch and can vary in size.

2. Painlessness: They often do not cause pain unless they become inflamed or infected.

3. Discharge: The white, non-sticky substance you mentioned is keratin, a protein that is a major component of skin, hair, and nails. When the cyst is squeezed, this keratin can be expelled.

4. Location: Common sites for these cysts include the face, neck, back, and areas where there is friction, such as the groin, thighs, and armpits.

Causes
The exact cause of subcutaneous cysts is not always clear, but several factors may contribute:
- Blocked Sebaceous Glands: These glands produce oil (sebum) that lubricates the skin. If the duct becomes blocked, a cyst can form.

- Genetic Predisposition: Some individuals may be more prone to developing cysts due to genetic factors.

- Skin Trauma: Previous injuries or skin conditions can lead to the formation of cysts.

- Obesity: While obesity itself is not a direct cause of cysts, it can contribute to skin friction and irritation, potentially leading to cyst formation.

Management and Treatment
1. Self-Care: If the cyst is not causing discomfort, it may not require treatment. However, if you choose to manage it at home, avoid squeezing or attempting to pop the cyst, as this can lead to infection.

2. Warm Compresses: Applying a warm compress can help reduce inflammation and promote drainage if the cyst is inflamed.

3. Over-the-Counter Treatments: Some topical treatments may help reduce inflammation, but they are unlikely to eliminate the cyst.

4. Medical Intervention: If the cyst becomes painful, infected, or bothersome, it is advisable to consult a healthcare provider. They may recommend:
- Incision and Drainage: A minor surgical procedure to drain the cyst and remove its contents.

- Excision: Complete removal of the cyst, which can prevent recurrence.

- Injection of Steroids: To reduce inflammation if the cyst is inflamed.

When to Seek Medical Attention
- If the cyst becomes red, swollen, or painful, indicating possible infection.

- If you notice changes in the cyst, such as rapid growth or changes in color.

- If you have multiple cysts or a family history of skin conditions.

Conclusion
Based on your description, it is likely that you are dealing with subcutaneous cysts. While they are generally harmless, monitoring their behavior is essential. If you experience any concerning symptoms or if the cysts continue to recur, it would be prudent to consult a dermatologist or healthcare provider for a thorough evaluation and appropriate management. They can provide tailored advice and treatment options based on your specific situation.
