What to expect from surgical excision for dermatofibroma

A dermatofibroma is a firm skin nodule that can catch on clothing, itch, feel tender, or remain uncertain on examination. During excision, the clinician numbs the skin, removes the nodule, and closes or dresses the wound according to its size and location. The tissue can be sent for microscopic assessment, especially when the appearance has changed or the diagnosis needs confirmation. Removing the nodule may not make the scar less noticeable than the original mark, and a dermatofibroma can recur rarely or another nodule can appear elsewhere. Your clinician can explain the balance between symptoms, diagnostic clarity, and the scar.

Keep the dressing in place for the advised period and wash the area gently when instructed. Avoid rubbing, picking, swimming, or movements that pull the wound until healing guidance allows them. Tell the clinic about medicines that affect bleeding and follow its pain-relief advice. Attend any wound check, stitch removal, or result appointment. When the wound has fully closed, protect the scar from strong sun and use any silicone or moisturising product only if recommended for your skin.

Contact the clinic if bleeding persists, the wound separates, or redness, heat, swelling, discharge, or pain is worsening rather than settling. Fever or a foul smell warrants prompt advice. Seek urgent help for uncontrolled bleeding or a rapidly enlarging swelling. A new lump, fast change in the scar, or a nodule that becomes persistently painful should be examined instead of being assumed to be a recurrence.

Ask whether removal is recommended for symptoms or diagnostic uncertainty, how large the scar may be, how the wound will close, and whether the tissue will be examined. Confirm when you can return to normal activities and which changes after healing should prompt reassessment.
