Local recurrence and intracerebral spread of squamous cell carcinoma of the scalp.

This case of squamous cell carcinoma of the scalp and malar region highlights the possibilities of therapeutic failure at the excisional, reconstructive, or histopathologic stage despite the performance of the appropriate, clinically indicated procedures and customary close examination of carcinoma patients and specimens. The extent of local recurrence and rapid intracerebral spread emphasize the occasionally aggressive nature of squamous cell carcinoma of the scalp and the need for early excision.
