260/280 purity ratio had a median of 1.87 in cytology versus 1.94 in histology. Mean DNA concentration for cytological preparations was 2653 ng / ml versus 757,2 ng/ml for histological preparations. DNA from all five cases of cytology were successfully amplified by conventional PCR, in contrast to none from the histology specimens. Conclusions Archived air-dried smears scraped from tumoral lesions in autopsies have proven to yield a good concentration of quality DNA for conventional PCR, with better results than formalin fixed pa
