Marjolin's ulcer (MDU) refers to malignant tumors that develop on unstable scars, resulting from chronic inflammation, trauma, or old burns. It is often a squamous cell carcinoma. We report a case of Marjolin's ulcer, which occurred 30 years after a thermal burn to the scalp, in a 35-year-old patient whose histological type is a poorly differentiated squamous cell carcinoma. The patient was a 35-year-old Malian farmer who presented with a scalp ulcer that had been developing for one year. Physical examination revealed a large (12 x 8 cm) ulcerated and proliferative tumor on the vertex of his head. There was no associated cervical lymphadenopathy. The remainder of the clinical examination was normal. The CT scan revealed a likely homogeneous, expansive, tissue-dense lesion with irregular external borders, arising from the frontal scalp without any obvious overlying lysis. No intracranial involvement was evident on unenhanced CT. Histological examination of a biopsy fragment confirmed the diagnosis of poorly differentiated squamous cell carcinoma.
