There are no standard investigations for the patient with a suspected keloid scar.
It is a clinical diagnosis based on the history and examination features. Rarely,
a locally agressive tumour such as dermatofibrosarcoma protruberans may present

of trauma. In this situation, a dermatology opinion is suggested and formal histological
biopsy may be necessary for diagnosis.
