Summary: Is there possibly more going on in this ear than 'just' basal cell carcinoma?

Lesion removed was inside of outer ear with a reaching tendril no further in canal than the cartilage. Both froz sections for clear margin came back as positive for cancer. Doc was surprised as the area looked perfectly normal on surface and he had taken quite a bit for a clear margin. He thinks bottom of ear will need to come off but had reached time limit for surgery set by cardiologist, etc. Is there more possibly going on here than just basal cell carcinoma?
