Tumor spectrum of mice deleted for <i>p53</i> and/or <i>Dicer</i> in skin.

A majority of tumors forming in the mice were fixed and classified by morphology after sectioning and staining with hematoxylin and eosin. The number of mice in cohort and the number of mice presenting with one or more tumors are given in second and third columns. Tumors undergoing histopathologic analysis and classified are given in fourth column, as are the numbers (and percentages) of mice presenting with multiple, simultaneous tumor formations (last column). SCC = squamous cell carcinoma, BCC = basal cell carcinoma, Carc = carcinoma, wd = well differentiated, md = moderately differentiated, pd = poorly differentiated, vpd = very poorly differentiated-undifferentiated.
