Bruises and Lumps in Children: What Parents Should Know - Pediatrics

Bruise lump


Hello Doctor, a while ago I might have accidentally bumped the inner side of my calf near the ankle, and a lump that looks like a bruise appeared.
It feels about 0.5 cm and isn't very prominent; you can only feel it by touch.
It's been almost a month.
I was very worried and kept pressing on it, which made it feel more painful, but in the past few days, since I haven't been pressing on it, the pain has improved a bit.
The lump hasn't changed in size over the past month.
I would like to ask you, Doctor, what might happen with this lump? Thank you.

Dr. Zhong Ruixian reply Pediatrics


Hello YY: It is recommended to observe for another 2-3 weeks.
If the lump enlarges and continues to be painful, you may visit a general surgeon.
Wishing you good health! Zhong Ruixian

When it comes to understanding bruises and lumps in children, it's essential for parents to be informed about the potential causes, symptoms, and when to seek medical attention. Bruises, or contusions, occur when small blood vessels under the skin break due to trauma, leading to discoloration and swelling. Lumps can arise from various factors, including injuries, infections, or even benign growths.

In your case, you mentioned experiencing a lump near your ankle that resembles a bruise and has persisted for almost a month. It’s good to hear that the pain has decreased and that the lump has not increased in size. Here are some considerations regarding your situation:
1. Nature of the Lump: Since the lump has been present for a month without significant changes, it may be a hematoma (a localized collection of blood outside of blood vessels) or a benign cyst. If it were a more serious condition, such as an infection or a tumor, you would likely see other symptoms, such as increased pain, redness, warmth, or fever.

2. Self-Examination: It’s important to avoid excessive manipulation of the lump, as pressing on it can cause further irritation and discomfort. If the lump is firm but not painful, and if it has not changed in size, it may not be a cause for concern. However, if you notice any changes, such as an increase in size, pain, or other symptoms, it would be wise to consult a healthcare professional.

3. When to Seek Medical Attention: Parents should seek medical advice if:
- The lump grows larger or becomes increasingly painful.

- There are signs of infection, such as redness, warmth, or discharge.

- The child experiences systemic symptoms like fever or malaise.

- The lump persists beyond a few weeks without improvement.

4. Potential Causes: In children, lumps can arise from various benign conditions, including:
- Lipomas: Soft, fatty lumps that are usually harmless.

- Sebaceous Cysts: Small lumps under the skin that can occur when hair follicles become blocked.

- Lymphadenopathy: Swollen lymph nodes due to infections or other causes.

5. Preventive Measures: To minimize the risk of bruises and lumps, encourage safe play and supervision during physical activities. Teaching children about their surroundings and how to avoid potential hazards can also help.

6. Consulting a Professional: If you remain concerned about the lump, consider scheduling an appointment with a pediatrician. They may perform a physical examination and, if necessary, order imaging tests like an ultrasound to assess the lump further.

In summary, while your lump may not be a cause for immediate concern, it’s essential to monitor it and consult a healthcare professional if any changes occur. Understanding the nature of bruises and lumps can help parents navigate their child's health more effectively, ensuring timely interventions when necessary. Always trust your instincts as a parent; if something feels off, it’s better to seek advice.
