Liquid-crystal thermography in determining the lateral extents of basal-cell carcinomas

Liquid-crystal thermography is a rapid, noninvasive, inexpensive method for determining the lateral extents of certain cutaneous malignancies. This report describes the technique as it is applied to basal-cell carcinomas. Results indicate that it is useful for neoplasms of moderate to heavy cellular density but little help in outlining neoplasms of low cellular density like morpheaform basal-cell carcinomas.
