a Long-Lasting Scalp Growth: Is It Dangerous? - Dermatology

When it comes to growths on the scalp, such as the small bump you described, there are several possibilities to consider. Based on your description—a small, flesh-colored bump that has been present for over 15 years without significant changes, pain, inflammation, or ulceration—it is likely to be a benign lesion. Here are some common types of growths that could match your description:
1. Seborrheic Keratosis: This is a non-cancerous skin growth that often appears as a brown, black, or light tan bump. They are common in older adults and can vary in size and shape. They typically do not cause any symptoms unless they are irritated.

2. Lipoma: A lipoma is a benign tumor made of fat tissue. They are usually soft, movable, and painless. Lipomas can occur anywhere on the body, including the scalp, and they generally do not change over time.

3. Dermatofibroma: This is a small, firm, raised growth that is usually brownish in color. It is benign and often occurs on the legs but can appear on the scalp as well.

4. Pilar Cyst: These cysts are common on the scalp and are filled with keratin. They are usually round, firm, and can be moved slightly under the skin. They are generally harmless and can remain stable for years.

Regarding your specific questions:
1. What could this small bump be?: Given its long-standing nature and lack of symptoms, it is most likely a benign growth such as a lipoma, seborrheic keratosis, or a pilar cyst. However, without a physical examination, it is impossible to provide a definitive diagnosis.

2. Is the risk of malignancy high?: The risk of malignancy in a long-standing, stable growth that has not changed in size or character over many years is generally low. Most skin cancers tend to change in appearance, grow, or present other symptoms such as pain or bleeding. However, it is essential to monitor any changes in the growth and consult a healthcare professional if you notice any changes.

While the likelihood of your growth being malignant is low, it is always wise to err on the side of caution. If you have any concerns, especially if the bump changes in size, color, or begins to cause discomfort, it would be prudent to consult a dermatologist. They may recommend a biopsy or other diagnostic procedures to rule out any serious conditions.

In summary, while your long-standing scalp growth is likely benign, regular monitoring and professional evaluation are essential for peace of mind and to ensure that any potential issues are addressed promptly. If you have further concerns or if the growth changes, do not hesitate to seek medical advice.
