Correct answer: E — Excision is not required — observe unless symptomatic, growing rapidly, or clinically atypical
Dermatofibromas are benign fibrous tumours that do not require excision. Indications for excision include: diagnostic uncertainty (atypical features on dermoscopy or clinical examination), symptomatic lesions (pain, pruritus), cosmetic concerns, rapid growth, or change in appearance suggesting a different diagnosis. Recurrence after incomplete excision is possible. Multiple eruptive dermatofibromas may be associated with immunosuppression (HIV, SLE, organ transplantation) and should prompt investigation. Dermoscopy (central white scar-like patch with peripheral delicate pigment network) can confirm the diagnosis non-invasively. Reassurance and discharge is appropriate for typical dermatofibromas.
