A patient attended with a small lump on the left calf that had been present for several years. The lesion was less than 1cm in size and showed no sinister features on examination. While dermatofibromas are harmless, some patients choose to have them removed for comfort or cosmetic reasons.
In this case, the patient opted for excision of the lesion after assessment.
What is a Dermatofibroma?
A dermatofibroma is a common benign skin growth that usually appears on the arms, legs, or trunk. It often feels firm, dome-shaped, and may be pigmented or darker than the surrounding skin. These lesions are completely non-cancerous and do not require treatment unless they become bothersome, irritated, or raised cosmetic concerns.
They can remain stable for many years, although some gradually flatten with time.
The Removal Procedure
The dermatofibroma removal procedure was performed under local anaesthetic using Lignospan LA. Once the area was fully numbed, an elliptical excision was carried out to remove the dermatofibroma in full. As the patient declined histological analysis, the tissue was not sent for laboratory testing.
The wound was closed using layered sutures: Monocryl for the deeper tissue and Rapide dissolvable stitches for the skin. Steri-strips and a Tegaderm dressing were applied for protection during healing.
Recovery and Aftercare
Following excision, patients are advised to keep the dressing in place for several days and avoid unnecessary strain on the wound while it heals. The scar usually settles well over time, although any excision will leave a fine line on the skin.
Because dermatofibromas are benign, once removed they do not return. However, new ones can occasionally form elsewhere on the body. Patients should seek review if they ever notice new or changing skin lumps.
