No histopathologic classification of observable mass performed. From later studies on other materials it has been learned that these would include: squamous cell carcinoma, benign epithelial papilloma, hyperkeratosis, acanthosis, and conditions of irritation having mono-nuclear cell invasion of tissue. It is estimated (from later studies) that at least 80% of observable masses would be classified as tumors (benign or malignant) with a great majority being benign epithelial papillomas.
