Growths under the skin?


Hello Dr.
Wu, I recently developed something on my face that looks like a pimple, but it is beneath the skin and feels raised.
It also hurts when I press on it firmly.
What could this be? Do I need to see a doctor? Thank you!

The information you provided is too limited, and without actually seeing the lesion, it cannot be confirmed.
If this is causing significant distress, it is advisable to seek medical attention as soon as possible.

When it comes to subcutaneous bumps, particularly those that feel painful when pressed, it is essential to understand the potential causes and when to seek medical attention. The bump you are describing could be a variety of things, including a sebaceous cyst, an epidermoid cyst, or even a lipoma. Each of these conditions has distinct characteristics and implications for treatment.

Sebaceous Cysts: These are common and typically form when a hair follicle becomes clogged with oil and dead skin cells. They can appear as small, round lumps under the skin and may become inflamed or infected, leading to pain and discomfort. If the cyst is not causing significant issues, it may not require immediate treatment, but if it becomes painful, red, or swollen, it is advisable to see a dermatologist.

Epidermoid Cysts: Similar to sebaceous cysts, epidermoid cysts are also formed from clogged hair follicles. They are usually harmless but can become inflamed or infected. If you notice changes in the cyst, such as increased pain, redness, or drainage, it is important to consult a healthcare provider.

Lipomas: These are benign tumors made of fat tissue and are usually soft and movable under the skin. They are generally painless but can cause discomfort if they press on nearby structures. If a lipoma grows rapidly or becomes painful, it is worth discussing with a dermatologist.

When to See a Dermatologist: You should consider making an appointment with a dermatologist if:
1. The bump is painful, especially if the pain is worsening.

2. There are changes in the size, shape, or color of the bump.

3. The bump becomes red, warm, or starts to drain pus.

4. You have concerns about the appearance or nature of the bump.

5. You have a history of skin cancer or other skin conditions.

In your case, since the bump is painful when pressed, it would be prudent to see a dermatologist. They can perform a physical examination and may recommend imaging studies or a biopsy if necessary to determine the exact nature of the bump. Early evaluation can help prevent complications, especially if there is a risk of infection or if the bump is symptomatic.

Conclusion: While many subcutaneous bumps are benign and may not require immediate treatment, any painful or changing lesion should be evaluated by a healthcare professional. Dermatologists are trained to diagnose and treat skin conditions effectively, ensuring that you receive the appropriate care based on your specific situation. If you are experiencing discomfort, do not hesitate to seek medical advice.
