A Practical Technique for Preparing Nail Matrix Biopsy Specimens for Melanonychia Diagnosis

Results: Higher dermal mitoses number was associated with decreased overall survival.Among patients with TMR 0, 1, 2-3, 4-10, and >10/mm 2 , 5-year overall survival (OS) was 97.3%, 93.6%, 88.3%, 73.0%, and 60.9%, respectively.In multivariate analyses, compared to TMR of 0/mm 2 , HR for all-cause mortality were 1.35 (95%CI: 1.08-1.68);1.70 (95%CI: 1.40-2.07);2.04 (95%CI: 1.67-2.49);and 2.39 (95%CI: 1.90-3.00)for 1, 2-3, 4-10, and >10 mitoses/mm 2 , respectively (Table1)
