Summary
Brief summary (as posted)
This prospective study of 60 slides of basal and squamous cell carcinomas of the skin aims to determine whether: 1. The process of cryofixation prior to generating formalin fixed paraffin embedded (FFPE) H\&E sections alters the histology in skin tumor specimens. 2. Which specific histologic parameters are altered between previously cryofixed versus routine FFPE sections. Histologic observations will be recorded by two dermatopathologists and two Mohs surgeons and statistically analyzed.

Inclusion Criteria: * Adult patients (age 18 or over) with a biopsy proven routine basal cell or squamous cell carcinoma of the skin who are scheduled for treatment with the Mohs procedure by Dr. Christopher Miller at the University of Pennsylvania's Division of Dermatologic Surgery will be included. Both female and male patients will be included. Exclusion Criteria: * Patients with basal cell or squamous cell carcinomas of more complex histopathology will be excluded from the study. Complex histopathology of a tumor is defined as features with aggressive, moderately to poorly differentiated, or unusual histopathology.
