Cutaneous basosquamous carcinoma of the head and neck: a comparative analysis

Considerable debate has taken place concerning cutaneous basosquamous carcinomas. Some authors believe they are merely a variant of basal cell carcinoma, based on the apparent rare occurrence of metastases. This comparative study of 33 cases of basosquamous, 1,796 cases of basal cell, and 736 cases of squamous carcinomas arising in the head and neck demonstrates that the basosquamous lesion has the potential to recur and to metastasize, which is similar to squamous cell lesions. An aggressive primary treatment program is recommended.
