The prognostic significance of tumor infiltrating lymphocyte (TIL) response in cutaneous melanoma is controversial. This analysis of data from a prospective, randomized trial included patients with cutaneous melanoma ≥ 1.0 mm Breslow thickness who underwent wide local excision and sentinel lymph node (SLN) biopsy. Univariate and multivariate analyses were performed to determine factors associated with TIL response, disease-free survival (DFS), and overall survival (OS). A total of 515 patients were included; TIL response was classified as “brisk” (n = 100; 19.4%) or “non-brisk” (n = 415; 80.6%). Patients in the nonbrisk TIL group were more likely to have tumor-positive SLN (17.6% vs 7%; P = 0.0087). On multivariate analysis, nonbrisk TIL response, increased tumor thickness, and ulceration were significant independent predictors of tumor-positive SLN. By Kaplan-Meier analysis, 5-year DFS rate was 91 per cent for those with a brisk TIL response compared with 86 per cent in the nonbrisk group ( P = 0.41). The 5-year OS rates were 95 per cent versus 84 per cent in the brisk versus nonbrisk TIL groups, respectively ( P = 0.0083). However, on multivariate analysis, TIL response was not a significant independent factor predicting DFS or OS. TIL response is a significant predictor of SLN metastasis but is not a major predictor of DFS or OS.

Manicures can result in nail damage via instrumentation, nail polish, nail polish removers, and artificial nails. We report nail weakness, brittleness, and thinning in five subjects after the application of a new manicure system called gel polish and removal with acetone and manual peeling. All subjects complained that the polish was very difficult to remove and that their nails became much thinner after the procedure. Pseudoleukonychia and onychoschizia lamellina were noted on examination. One subject underwent ultrasound and reflectance confocal microscopy (RCM) measurements of nail plate before and after the gel polish application, which showed thinned nail plate (0.063 vs. 0.050 cm and 0.059 vs. 0.030 cm, respectively). Overall, we call attention to the adverse effects of gel polish manicures in five subjects. In addition, our case illustrates potential utility of ultrasound and RCM in measuring nail plate thickness.

This study shows that postoperative pain is affected by pain anxiety, even in dermatologic surgery. However, most patients still had very little discomfort after surgery, further supporting MMS as an effective and safe procedure with relatively few postoperative problems.
