A patient with a basal cell carcinoma infiltrating the superior sagittal sinus and involving a wide area on the scalp was successfully excised. Two lesions, one in the right frontotemporal region and the other in the temporo-parieto-occipital region, were present. Surgical resection of the two lesions was performed on two separate occasions. The tumor had invaded a wide area of the temporo-parieto-occipital region, and because of this, the scalp, skull and dura mater, together with a large part of the superior sagittal sinus, were excised. The resulting defect was reconstructed simultaneously. At one year follow-up, there was no recurrence of the lesion. © 1995 Springer Verlag.
