Inguinal mass


There is a lump in the left groin area that is at least 3-5 centimeters in size.
It can be clearly felt as a spherical mass inside.
It causes pus and bleeding when accidentally bumped, and squeezing it results in severe pain.
I would like to understand what kind of lesion this might be.

Dr. Wu Yuxin reply Dermatology


Without actually seeing the lesion, it is impossible to determine the issue.
If it is very concerning, please seek medical attention as soon as possible.
Only after an examination can the problem be identified and addressed.

Understanding groin lumps can be crucial for determining the underlying cause and appropriate treatment options. A lump in the groin area, especially one that is palpable, painful, and has the potential to ooze pus or blood, can arise from various conditions. Here, we will explore the possible causes, symptoms, and treatment options related to groin lumps.


Possible Causes of Groin Lumps
1. Lymphadenopathy: One of the most common causes of lumps in the groin is swollen lymph nodes, which can occur due to infections (such as sexually transmitted infections, skin infections, or systemic infections), inflammatory conditions, or malignancies. Lymph nodes can become enlarged and tender, leading to noticeable lumps.

2. Hernias: An inguinal hernia occurs when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles. This can create a bulge in the groin area, which may be painful, especially when straining or lifting.

3. Abscess: A localized collection of pus that can form due to bacterial infection. Abscesses can be painful, swollen, and may drain pus or blood if they rupture.

4. Sebaceous Cysts: These are non-cancerous lumps that can form under the skin when sebaceous glands become blocked. They are usually painless but can become infected, leading to inflammation and discomfort.

5. Lipomas: These are benign tumors made of fatty tissue. They are typically soft, movable, and painless, but larger lipomas can cause discomfort if they press on surrounding structures.

6. Testicular Issues: In males, conditions such as epididymitis (inflammation of the epididymis) or testicular torsion can present with groin pain and swelling.

7. Tumors: Both benign and malignant tumors can present as lumps in the groin. While less common, it is essential to consider this possibility, especially if the lump is hard, fixed, or growing.


Symptoms to Watch For
- Pain: The severity of pain can vary depending on the underlying cause. Pain may be sharp, throbbing, or aching and can worsen with movement or pressure.

- Swelling: The size of the lump can change, and surrounding tissues may also appear swollen.

- Discharge: If the lump is infected, it may ooze pus or blood.

- Fever: Accompanying systemic symptoms like fever may indicate an infection.

- Changes in Urination: If the lump is related to urinary structures, changes in urination patterns may occur.


Treatment Options
1. Observation: If the lump is small, painless, and not causing any symptoms, a watchful waiting approach may be appropriate.

2. Medications: Antibiotics may be prescribed if the lump is due to an infection. Pain relievers can help manage discomfort.

3. Incision and Drainage: For abscesses, a healthcare provider may need to drain the pus to relieve pressure and promote healing.

4. Surgery: In cases of hernias, tumors, or persistent cysts, surgical intervention may be necessary to remove the lump or repair the underlying issue.

5. Follow-Up: Regular follow-up appointments may be required to monitor the lump, especially if there is a concern for malignancy.


When to Seek Medical Attention
It is essential to seek medical attention if you notice a lump in your groin that is painful, growing, or associated with systemic symptoms like fever or chills. A healthcare provider can perform a thorough examination, possibly including imaging studies or biopsies, to determine the exact cause of the lump and recommend appropriate treatment.

In conclusion, while groin lumps can arise from various conditions, understanding the potential causes and symptoms can guide you in seeking timely medical care. Always consult a healthcare professional for an accurate diagnosis and tailored treatment plan.
