Common Benign Lesions
Moles (melanocytic naevi), epidermoid cysts (sometimes called sebaceous cysts), and lipomas are among the most common lesions referred for removal. Most are entirely benign and removed for symptomatic relief (catching on clothing, recurrent infection, discomfort) or cosmetic preference; occasionally removal is recommended where there is diagnostic uncertainty.
Indications
- Cosmetic preference for removal of a benign, stable mole
- Recurrent infection or inflammation of an epidermoid cyst
- Lesions that catch on clothing, jewellery or razors
- Diagnostic uncertainty, where excision biopsy allows histological confirmation
- Growing, changing or symptomatic lipomas
Any mole showing asymmetry, an irregular border, colour variation, a diameter over 6mm or recent change (the “ABCDE” signs), or any lesion you are worried may be skin cancer, should be assessed urgently rather than as routine cosmetic removal — see Skin Cancer Excision & Reconstruction or speak to your GP about an urgent referral.
The Procedure
Performed under local anaesthetic as a day case. Technique depends on the lesion: shave excision for some raised moles, full excision with sutured closure for cysts, lipomas and moles requiring histology. All excised tissue is routinely sent for histopathology. Lipomas may require a slightly longer incision than the lump itself to allow complete removal of the fibrous capsule and reduce recurrence.
Aftercare
- Keep the wound clean and dry per your specific aftercare instructions
- Sutures, where used, are typically removed at 7–14 days depending on site
- Histology results are discussed at a follow-up appointment
- Scarring settles over several months; sun protection to the area is advised for 6 months
Risks
Scarring
All excisions leave a scar; care is taken with placement and closure to minimise visibility.
Infection
Uncommon; managed with wound care and antibiotics if needed.
Cyst Recurrence
Can occur if the cyst wall is not completely removed; more likely with previously inflamed or ruptured cysts.
Bleeding & Bruising
Usually minor and self-limiting.
