Benign & Complex Soft Tissue Lesions
Benign & Complex Soft Tissue Lesions
Consultant Colorectal and General Surgeon in London
Soft tissue lesions range from common benign lumps (lipomas, sebaceous cysts, fibromas, desmoids) to complex, locally aggressive tumours that are not frankly malignant. Accurate diagnosis and appropriate management are essential to relieve symptoms, rule out malignancy, and prevent recurrence. Mr Nikhil Pawa offers comprehensive assessment and treatment for benign and complex soft tissue lesions, including clinical examination, advanced imaging, core biopsy, and surgical excision.
Malignant sarcomas and high‑grade tumours are referred promptly to a specialist sarcoma multidisciplinary team for definitive oncological management, ensuring you receive the right level of care at the right time.

Benefits of Managing Benign & Complex Lesions
01
Accurate Diagnosis First
MRI, ultrasound, and core needle biopsy distinguish harmless lumps from complex or early malignant lesions — avoiding over‑treatment or dangerous delays.
02
Symptom Relief
Excision of painful, enlarging, or cosmetically bothersome lesions eliminates discomfort, improves mobility, and restores confidence.
03
Prevents Recurrence
Complete surgical excision with clear margins (where appropriate) reduces the risk of regrowth for complex benign tumours like desmoids or recurrent lipomas.
04
Minimally Invasive Excision
Small, superficial lesions can be removed under local anaesthetic through tiny incisions, with excellent cosmetic results and minimal downtime.
05
Clear Referral Pathway for Malignancy
If histopathology reveals a sarcoma or high‑grade malignancy, Mr Pawa coordinates immediate referral to a specialist sarcoma centre for multidisciplinary care.
06
Management of Complex Benign Tumours
Lesions such as desmoid fibromatosis, intramuscular lipomas, or neurofibromas are managed with surveillance, medical therapy, or wide local excision as appropriate.
07
Patient‑Centred Shared Decision Making
You receive a clear explanation of your diagnosis, treatment options, and the rationale for referral if malignancy is suspected — no surprises.

Performed by a Global Expert
Mr. Nikhil Pawa brings over 20 years of experience in soft tissue lesion excision and complex benign tumour management, working closely with London’s sarcoma networks.
Our Process
Specialist Consultation
Your journey begins with a thorough consultation with Mr Nikhil Pawa, where your lump’s size, depth, growth rate, pain, and any previous excisions are carefully assessed.
Advanced Imaging
We arrange same‑week ultrasound to characterise the lesion (solid, cystic, vascular, deep to fascia) and an MRI to define exact anatomical margins and any aggressive features (size >5cm, infiltrative edges, perilesional oedema).
Core Needle Biopsy (If Indicated)
If the lesion is deep, large (>5cm), or has suspicious imaging features, a core needle biopsy under ultrasound guidance is performed. Histopathology and, if needed, molecular testing guide the diagnosis.
Tailored Management Plan
Small benign lesions: surveillance. Symptomatic/enlarging benign: excision (local/GA). Complex benign (e.g., desmoid): surveillance, medical therapy, or wide excision. Malignant: immediate referral to sarcoma MDT.

FAQs
Benign soft tissue lesions are non‑cancerous growths such as lipomas (fatty tumours), sebaceous cysts, fibromas, neurofibromas, and desmoid tumours (aggressive but non‑metastasising).
Complex benign lesions are those that are deep, large (>5cm), locally aggressive (e.g., desmoid fibromatosis), recurrent, or causing symptoms due to nerve or vessel compression. They require expert imaging and may need wide excision.
If core biopsy shows a sarcoma (malignant soft tissue tumour), high‑grade undifferentiated sarcoma, or any tumour that requires sarcoma‑specialist surgery (e.g., limb‑sparing resection with reconstruction), Mr Pawa refers you immediately to a specialist sarcoma MDT.
Yes. Most small to medium (<5cm) superficial lipomas and sebaceous cysts can be removed under local anaesthetic as a 20‑30 minute office procedure, with rapid return to normal activities.
Recurrence after complete excision is low (<2-5% for lipomas, <10-15% for desmoids). Incomplete excision (e.g., enucleation of a dumbbell lipoma) carries higher risk. Mr Pawa aims for complete marginal excision where safe and appropriate.
Histopathology results are typically available within 5-7 working days. Complex cases (e.g., desmoid or possible sarcoma) may require additional immunohistochemistry or molecular studies, taking 10-14 days.
