Soft Tissue Masses & Lipomas
Finding a lump beneath the skin can be concerning. Although most soft tissue masses, such as lipomas (fatty tumors), are benign, any new, enlarging, or painful lump should be evaluated. At The Medical Group of New Jersey, our general surgeons diagnose and treat soft tissue masses using imaging and biopsy when appropriate. When surgical removal is recommended, we focus on complete excision, accurate diagnosis, and excellent cosmetic and functional outcomes.
Symptom Onset & Initial Evaluation
Many soft tissue masses are discovered accidentally while bathing, dressing, or exercising. Others may slowly enlarge over months or years before becoming noticeable.
Common reasons patients seek evaluation include:
- A new lump beneath the skin
- A mass that is gradually increasing in size
- Pain or tenderness
- Pressure on nearby nerves or muscles
- Discomfort with movement or exercise
- A visible lump that causes cosmetic concerns
Most lipomas are soft, movable beneath the skin, and painless. However, not every soft tissue mass is a lipoma, making professional evaluation important.
Certain symptoms require prompt medical evaluation, including:
- Rapid growth
- Persistent pain
- Firm or fixed masses
- Skin ulceration
- Drainage or bleeding
- Changes in skin color over the mass
- Unexplained weight loss or persistent fatigue
Although these findings do not necessarily indicate cancer, they require timely assessment.
Evaluation
During your consultation, your surgeon will perform a detailed evaluation to determine the most likely cause of the mass.
This includes:
- Reviewing when the mass first appeared
- Determining whether it has changed in size
- Discussing pain, drainage, redness, or tenderness
- Reviewing previous injuries or surgeries in the area
- Assessing family history of tumors or cancers
- Performing a careful physical examination
Many benign masses can be identified based on their location, texture, mobility, and growth pattern. However, additional testing may be recommended to confirm the diagnosis.
Diagnosis & Risk Assessment
The evaluation of a soft tissue mass is aimed at determining whether it is benign or requires further investigation.
Physical Examination
Your surgeon will assess:
- Location of the mass
- Size and shape
- Consistency (soft, rubbery, or firm)
- Mobility beneath the skin
- Tenderness
- Skin changes
- Whether nearby lymph nodes are enlarged
These findings often provide important clues about the nature of the mass.
Ultrasound
Ultrasound is frequently the first imaging study used for superficial soft tissue masses. It is painless, does not use radiation, and is often sufficient for evaluating smaller superficial masses. It can help determine:
- Whether the mass is solid or fluid-filled
- Its size and depth
- Whether blood flow is present within the lesion
- Whether the findings are consistent with a lipoma or cyst
Magnetic Resonance Imaging (MRI)
For larger, deeper, or more complex masses, MRI provides highly detailed images of muscles, fat, nerves, and connective tissues. MRI helps your surgeon:
- Define the exact size and location
- Determine whether nearby structures are involved
- Differentiate benign from potentially aggressive tumors
- Plan the safest surgical approach
MRI is particularly valuable when a mass is located beneath muscle or near important nerves or blood vessels.
CT Scan
CT imaging may occasionally be recommended for masses located deeper within the body or when MRI is not appropriate.
Biopsy
Some masses require tissue sampling before surgery. Depending on the characteristics of the lesion, your surgeon may recommend:
- Fine needle aspiration (FNA)
- Core needle biopsy
- Excisional biopsy (complete removal)
The biopsy allows a pathologist to determine the exact diagnosis and helps guide treatment planning.
Risk Assessment
Your surgeon will evaluate several factors that influence treatment recommendations, including:
- Size of the mass
- Growth rate
- Location
- Imaging characteristics
- Patient age
- Personal or family history of cancer
- Previous radiation exposure
- Overall health
This individualized assessment helps determine whether observation or surgical removal is the most appropriate option.
Treatment & Management
Treatment depends on the diagnosis, symptoms, and risk of future complications.
Observation
Many small lipomas and other benign soft tissue masses do not require immediate treatment. Observation may be appropriate when the mass:
- Has imaging features consistent with a benign lesion
- Is not growing
- Causes no pain or functional limitations
- Does not interfere with daily activities
Surgical Excision
Surgical removal is often recommended when a mass:
- Continues to enlarge
- Causes pain or discomfort
- Restricts movement
- Becomes cosmetically bothersome
- Has uncertain imaging findings
- Requires definitive diagnosis
- Shows features concerning for malignancy
The procedure is frequently performed on an outpatient basis using local anesthesia, sedation, or general anesthesia depending on the size and location of the mass. The goal is complete removal while preserving surrounding healthy tissue and minimizing scarring whenever possible.
Specialized Care for Complex Tumors
If testing suggests a rare or malignant soft tissue tumor, your surgeon will coordinate care with oncology, radiology, and other specialists to develop the most appropriate treatment plan. This collaborative approach ensures that patients receive comprehensive, evidence-based care.
Recovery & Follow-Up
Recovery depends on the size and location of the mass, as well as the type of procedure performed. After surgery, your care team will provide instructions regarding:
- Incision care
- Activity restrictions
- Pain management
- Signs of infection
- When to return to work or exercise
- Pathology results
Most patients return to normal daily activities within a few days, although larger procedures may require a longer recovery period.
Follow-up visits allow your surgeon to monitor healing, review pathology findings, and determine whether any additional treatment is needed.
Prognosis & Preventive Care
When complete surgical removal is performed, recurrence is uncommon for most lipomas and other benign tumors. Patients should continue to monitor their skin and soft tissues and seek medical evaluation for:
- New lumps
- Rapidly enlarging masses
- Persistent pain
- Changes in existing growths
Early evaluation allows many conditions to be diagnosed and treated before they become more complex.
At The Medical Group of New Jersey, our general surgeons are committed to providing accurate diagnosis, individualized treatment, and compassionate care, helping patients achieve the best possible outcomes while minimizing unnecessary procedures.
