"Pathologically, Marjolin ulcers are characterised by malignancy within a cutaneous scar 1, commonly caused by burns or trauma 3. Squamous cell carcinoma is the most common malignancy identified in the vast majority of cases (>70%), followed by basal cell carcinoma and melanoma 5. Very rarely, tumours such as fibrosarcoma, liposarcoma, dermatofibrosarcoma, and osteosarcoma have been noted 6. Malignant transformation starts with acanthosis, then basal cell hyperplasia, pseudo-epitheliomatous hyperplasia, atypical basal cell changes, and ends with carcinomatous changes 6."
