BACKGROUND: The American Joint Commission on Cancer will remove mitotic rate from its staging guidelines in 2018. OBJECTIVE: Using a large nationally-representative cohort, we examined the association between mitotic rate and lymph node positivity among thin melanomas. METHODS: 149,273 thin melanomas in the National Cancer Database were examined for their association between high-risk features of mitotic rate, ulceration, and Breslow depth, with lymph node status...

BACKGROUND AND OBJECTIVES: Indications for sentinel lymph node (SLN) biopsy in patients with thin melanoma (≤1 mm thick) are controversial. We asked whether deep margin (DM) positivity at initial biopsy of thin melanoma is associated with SLN positivity. METHODS: Cases were identified using prospectively maintained databases at two melanoma centers. Patients who had undergone SLN biopsy for melanoma ≤1 mm were included. DM status was assessed for association with SLN metastasis in univariate and multivariate analyses...

Scalp melanoma comprises 3-5% of all cutaneous melanomas. The median age of the patients is 53 years and males are more frequently affected. The scalp melanomas tend to have nodular histology with a higher mitotic rate (>3/mm) and poorer prognosis (1). The risk factors for development of this tumor are still not defined but UV light and baldness may play a significant role (2-4). Mesotherapy is a non-surgical procedure currently being used to combat hair loss and promote hair growth. Usually a mixture of vitamins, minerals, growth factors, DHT blockers and/or stem cells extracts is injected into the dermal layer of skin (5,6)...

PURPOSE: S100B protein is currently used as an immunohistochemistry marker to confirm melanoma diagnosis in biopsy specimens. Moreover, accumulating evidence supports its potential use as a tumor biomarker in blood. This study aimed to explore the potential uses of serum S100B protein as a biomarker in melanoma patients. METHODS: From 2012 to 2015, 107 sequential patients were diagnosed and treated for melanoma. All patients were tested for serum S100B and lactate dehydrogenase (LDH) at diagnosis and during their regular follow-up...

BACKGROUND: Nodular melanoma (NM) accounts for most thick melanomas and because of their frequent association with ulceration, fast growth rate and high mitotic rate, contribute substantially to melanoma-related mortality. In a multicentric series of 214 primary melanomas including 96 NM and 118 superficial spreading melanoma (SSM), histopathological features were examined with the aim to identify clinicopathological predictors of recurrence. METHODS: All consecutive cases of histopathologically diagnosed primary invasive SSM and NM during the period 2005-2010, were retrieved from the 12 participating Italian Melanoma Intergroup (IMI) centers...

BACKGROUND: In 2010, the National Comprehensive Cancer Network (NCCN) recommended sentinel lymph node biopsy (SLNB) for thin melanomas ≤1 mm with mitotic rate (MR) ≥1. In 2016, the criteria were changed to Breslow depth >0.75 mm and MR ≥1. OBJECTIVE: To compare the impact of 2010 and 2016 NCCN guidelines on SLNB case selection and thin melanoma outcomes. MATERIALS AND METHODS: Ten-year retrospective cohort of primary thin melanomas at an academic hospital was retroactively stratified for SLNB eligibility using the 2010 and 2016 NCCN guidelines...

Importance: Digital pathology represents a transformative technology that impacts dermatologists and dermatopathologists from residency to academic and private practice. Two concerns are accuracy of interpretation from whole-slide images (WSI) and effect on workflow. Studies of considerably large series involving single-organ systems are lacking. Objective: To evaluate whether diagnosis from WSI on a digital microscope is inferior to diagnosis of glass slides from traditional microscopy (TM) in a large cohort of dermatopathology cases with attention on image resolution, specifically eosinophils in inflammatory cases and mitotic figures in melanomas, and to measure the workflow efficiency of WSI compared with TM...

Tumor mitotic rate (TMR) is a known prognostic variable in thin melanoma patients. Its significance in stage II melanoma patients is yet to be demonstrated. Retrospective analysis of a prospective melanoma database from 9/1997 to 7/2015 was performed. All stage II melanoma, with documented TMR, and six months of follow-up were included. We evaluated the association of clinicopathologic variables, TMR, as a continuous and categorical variable with recurrence-free survival (RFS) and overall survival (OS) using Cox proportional hazards modeling...

BACKGROUND: Time between primary melanoma excision and sentinel lymph node biopsy (SLNB) has not been sufficiently studied as an independent predictor of survival in cutaneous melanoma. OBJECTIVES: We used propensity score matching to evaluate whether early SLNB (performed ≤40 days from excisional biopsy) is associated with higher mortality in patients with cutaneous melanoma. MATERIALS & METHODS: A retrospective cohort study at a tertiary melanoma referral centre...

AIMS: Metastatic melanoma involving the epidermis and/or upper dermis may show significant histologic overlap with primary cutaneous melanoma, especially the nodular subtype. Proper histopathologic classification is crucial to appropriate staging and management, yet often challenging. This study aims to identify helpful histopathologic features in differentiating epidermotropic/dermal metastatic melanoma (EDMM) and primary nodular melanoma (PNM). METHODS AND RESULTS: A cohort of EDMM (n=74) and PNM (n=75) was retrospectively reviewed for various histopathologic features, and the data were compared between groups by univariate analysis...

The latest reviews on thin melanoma (TM) continue to consider it a melanoma within 1 mm in thickness, but no consensus exists as to which patients with TM are at risk for lymph node metastases (1). Numerous studies have evaluated the impact of various predictors (Breslow thickness, Clark level, ulceration, regression, vascular invasion, mitotic activity, location, sex) for nodal disease in melanoma, but the conclusions have not been homogenous (2,3). For this reason, we read the paper by Homolak et al. with great interest, where the authors examine the sentinel lymph node biopsies (SLNB) of 184 patients affected by melanoma of thickness less than 1...

Ulcerated primary melanomas are associated with an inflammatory tumor microenvironment. We hypothesized that systemic proinflammatory states and anti-inflammatory medications are also associated with a diagnosis of ulcerated melanoma. In a cross-sectional study of 787 patients with newly diagnosed clinical stage IB or II melanoma, we estimated odds ratios for the association of proinflammatory factors (high body mass index, diabetes, cardiovascular disease, hypertension, and smoking) or the use of anti-inflammatory medications (statins, aspirin, corticosteroids, and nonsteroidal anti-inflammatory drugs), with ulcerated primary melanoma using regression models and subgroup analyses to control for melanoma thickness and mitotic rate...

BACKGROUND: T1 melanoma substaging was recently modified by the American Joint Committee on Cancer (AJCC). Although sentinel lymph node (SLN) positivity is the most important prognostic factor in melanoma, there is a lack of consensus on whether SLN biopsy should be performed in patients with thin melanoma (≤1 mm). OBJECTIVE: The main aim of this study was to investigate predictors of SLN positivity in patients with thin melanoma, with a special emphasis on mitotic rate...

BACKGROUND AND OBJECTIVES: Current literature may overestimate the risk of nodal metastasis from thin melanoma due to reporting of data only from lesions treated with SLNB. Our objective was to define the natural history of thin melanoma, assessing the likelihood of nodal disease, in order to guide selection for SLNB. METHODS: Retrospective review. The primary outcome was the rate of nodal disease. Clinicopathologic factors were evaluated to find associations with nodal disease...

BACKGROUND: Recent molecular advances suggest that Spitz nevi and other spitzoid neoplasms are biologically distinct from melanoma and conventional nevi. The ubiquitin ligase UBE2C and the homeobox transcription factor HOXA1 are candidate oncogenes in melanoma. METHODS: Using RNA expression analysis and immunohistochemistry, we evaluated these biomarkers in Spitz nevi (n = 20), melanoma (n = 20), and by immunohistochemistry in conventional nevi (n = 20)...

BACKGROUND: Polo-like kinase-1 (PLK-1) is one of the key regulators of cell cycle progression. Increased expression of PLK-1 was observed in several tumor types. METHODS: We immunohistochemically assessed PLK-1 expression in neoplastic and stromal compartments of 96 cutaneous melanomas, and analyzed associations between PLK-1 expression and clinicopathological characteristics. RESULTS: PLK-1 expression in cancer cells was not associated with basic clinical (eg, age, gender and tumor location) or histopathological (eg, Breslow thickness, mitotic rate and ulceration) parameters...

Dermatofibromas (DF) are common, benign, skin tumors, usually easily differentiated from dermatofibrosarcoma protuberans (DFSP) by the presence of a relative low cellularity, lesser degree of infiltration of subcutaneous tissue, and immunohistochemical pattern (eg, FXIIIa in DF and CD34 in DFSP). Atypical fibrohistiocytic lesions (AFL) have features intermediate to DF and DFSP (trunk location, storiform pattern, infiltration of the subcutaneous tissue, and focal expression of both CD34 and Factor XIIIa). It is unclear if mitotic counts/degree of proliferation is helpful to distinguish DF from DFSP...

The combinatorial chemotherapy that has emerged as a promising treatment modality for intractable cancers is challenged by lack of tumor-targeting, robust and ratiometric dual drug release systems. Here, docetaxel-loaded cRGD peptide-decorated redox-activable micellar mertansine prodrug (DTX-cRGD-MMP) was developed for targeted and synergistic treatment of B16F10 melanoma-bearing C57BL/6 mice. DTX-cRGD-MMP exhibited a small size of ca. 49 nm, high DTX and DM1 loading, low drug leakage under physiological conditions, while rapid release of both DTX and DM1 under a cytoplasmic reductive environment...
