Q: Subcutaneous Lumps in Children: Causes and When to Seek Help

Hello： It is recommended to seek treatment at a general surgery or plastic surgery outpatient clinic for a clearer understanding. <br>Thank you!

Medical Consultation - Subcutaneous Yellowish Nodules

About ten days ago, my two-year-old daughter sustained a bruise on the inner side of her right calf (approximately 5 cm long and 3 cm wide) due to a collision.
The color of the bruise has significantly faded, but a lump resembling a soybean has appeared at the site of the bruise.
Could this lump be a result of the collision, or could there be another cause? Should further examination be necessary, which specialty should we consult? Thank you!

When it comes to understanding subcutaneous lumps in children, particularly in the context of your two-year-old daughter who has developed a lump following a bruise, there are several important considerations to keep in mind.
Firstly, it is not uncommon for children to develop lumps or bumps after an injury. The lump you describe, which has appeared in the area of the bruise, could be a result of several factors related to the trauma. Common causes of such lumps include:
1. Hematoma: This is a localized collection of blood outside of blood vessels, often resulting from trauma. As the bruise heals, a hematoma may form, which can feel firm or lumpy to the touch. Over time, hematomas typically resolve on their own as the body reabsorbs the blood.

2. Lipoma: While less likely in this scenario, a lipoma is a benign tumor made of fat tissue. These are generally soft and movable under the skin and are usually painless. If the lump persists long after the bruise has healed, it may warrant further investigation.

3. Cyst: Sebaceous cysts can also form in response to trauma or irritation. These are typically filled with a thick, oily substance and can feel firm or soft depending on their contents.

4. Infection: If the lump becomes red, warm, or painful, it could indicate an infection, which would require medical attention.

Given that the bruise has significantly faded but the lump remains, it is advisable to monitor the lump closely. If it continues to grow, changes in appearance, or if your daughter experiences pain or discomfort, it would be prudent to seek medical evaluation.

In terms of which specialist to consult, a pediatrician would be the best first step. They can perform a physical examination and determine if any further imaging or tests are necessary. If the pediatrician feels it is warranted, they may refer you to a pediatric surgeon or a pediatric dermatologist for further evaluation.

In summary, while the lump could very well be a benign result of the bruise, it is essential to keep an eye on it. If there are any concerning changes or if you have any doubts, do not hesitate to seek medical advice. Early intervention can often lead to better outcomes and peace of mind for parents.
