Hello Mr.
Lin,
From your description, it is clear that you place great importance on your health.
Congratulations on noticing the small oval hard lump approximately 0.3 cm above your inner ankle six months ago.
Initially, it did not have any discoloration, but now it has slightly protruded and grown to about 0.4 cm in an oval shape, turning pink in color.
However, it is neither painful nor itchy.

Based on your description, it is likely just a dermatological symptom.
There could be many possible causes, such as trauma, insect bites, or a benign skin tumor.
As long as it is not a black mole, you should feel reassured.
However, it is still advisable to visit a general surgery outpatient clinic for a physician to confirm that there are no issues or to conduct further examinations.

Wishing you good health and happiness,
Dr.

More Info

Based on your description of a small, oval-shaped bump on your inner ankle that has been present for six months and has slightly increased in size and changed color, it is important to consider several possibilities regarding its nature. The fact that it is not painful or itchy is a notable aspect, but changes in size and color warrant further investigation.

1. Possible Causes:
- Lipoma: This is a benign tumor made of fat tissue. Lipomas are typically soft, movable, and painless. They can vary in size and may change in appearance over time.

- Dermatofibroma: This is a common benign skin growth that can appear as a firm bump on the skin. They are often brownish or pink and can be slightly raised. They are usually harmless and do not require treatment unless they become bothersome.

- Sebaceous Cyst: These are small lumps beneath the skin that can occur when a sebaceous gland becomes blocked. They are usually painless and can vary in size.

- Keloid or Hypertrophic Scar: If there has been any previous injury or irritation in the area, a keloid or hypertrophic scar could develop, which is a raised area of scar tissue that can change in color and size.

- Ganglion Cyst: These are fluid-filled sacs that can develop near joints or tendons, often appearing as a lump. They can fluctuate in size and may not cause pain.

2. When to Seek Medical Attention:
- While many of these conditions are benign, it is essential to monitor any changes in the bump. If you notice an increase in size, changes in color, or if it becomes painful or begins to itch, it is advisable to consult a healthcare professional.

- Additionally, if the bump starts to affect your mobility or causes discomfort during activities, a medical evaluation would be warranted.

3. Recommended Actions:
- Consult a Dermatologist: Given the changes in size and color, it would be prudent to see a dermatologist. They can perform a physical examination and may recommend a biopsy or imaging studies if necessary to determine the nature of the bump.

- Keep a Record: Document any changes in the bump, including size, color, and any associated symptoms. This information can be helpful for your healthcare provider in making a diagnosis.

4. Potential Treatments:
- If the bump is diagnosed as a benign growth and is not causing any issues, treatment may not be necessary. However, if it is bothersome or if there is a concern about its nature, options may include surgical removal or other interventions based on the diagnosis.

In summary, while the bump on your ankle may be benign, the changes in its characteristics suggest that a professional evaluation is warranted. A dermatologist will be able to provide a more accurate diagnosis and recommend appropriate management based on their findings. It is always better to err on the side of caution when it comes to changes in your skin or underlying tissues.
