A case in which motor evoked potential could be elicited despite an increase in remifentanil dose during craniotomy.

Introduction:Basosquamous cell carcinoma (BSC) is a rare cutaneous neoplasm with features of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) which has a potential for aggressive infiltration and destruction. BSC has reported incidence rate of 1-2% of all carcinomas of the skin. Here we discuss a rare presentation of BSC with review of literature.Material and methods: An elderly male presented with an ulcer over the left temporal region and history of loss of ear lobule 6 years back. Formalin fixed tissue sections were stained with hematoxylin and eosin. Histopathology revealed basosquamous carcinoma. Conclusion: Basosquamous carcinoma is a rare aggressive skin tumor with a propensity for lymph node and distant metastases. It is radioresistant and has a poor prognosis. Surgical excision with negative margins and long term follow-up are essential.
