Sarcomatoid Carcinoma of the Scalp - Case Report

Carcinosarcoma is a rare malignant tumour of the head and neck region, combining epithelial and mesenchymal components. The lack of reported cases prevents the establishment of standardised norms for the treatment of this type of cancer. We report the case of ́a 75-year-old man, who presented with a left parietal scalp wound, a biopsy of which returned in favour of follicular basal cell cancer. The patient underwent surgery to remove the tumour, followed by coverage of the area with a parietal flap and a graft from the donor area a week later with histopathological study of the excision specimen in favour of basal cell sarcomatoid carcinoma with healthy margins. The raritý of this tumour in particular in this location poses a diagnostic problem and timely management. However, wide surgical excision remains the best treatment. Through this case we have highlighted the particularities of the rapid evolution and especially prognosis of this tumour.
