purpose: to define the demographic and clinical features of eyelid masses at a referral hospital over a 10-year period. methods: this is a retrospective record-based study on patients with eyelid masses during the above-mentioned period. data on epidemiologic and clinical features and therapeutic approaches were collected and analyzed. results: 551 patients were included in the study from which...

elanocytes causing depigmentation at the periphery of melanocytic nevi. Clinically and dermoscopically these lesions can be difficult to distinguish from melanoma. Our case report shows our approach safe non-invasive monitoring using reflectance confocal microscopy 3-GEP PLA tests.

A large number of publications recognize that there are melanocytic lesions with microscopic features similar to melanoma, related to their location. Those locations are represented by the ear, the milk lines (axillary, breast, periumbilical and inguinal regions), palms, soles, and flexural regions. Starting from Rongioletti F et al. study in 2004, we measured 10 histological parameters on 96 n...

PURPOSE To gain a better understanding of the molecular events leading to the development of conjunctival melanocytic lesions and conjunctival melanoma, this study was conducted to investigate the presence of T1799A BRAF oncogenic mutation in these lesions. METHODS Forty-eight surgically excised conjunctival melanocytic lesions from 48 patients were examined for the presence of the BRAF T1799...

OBJECTIVE The aim of this study was to analyze the immunohistochemical expression of Skp2 protein in 38 oral nevi and 11 primary oral melanomas. STUDY DESIGN Expression of this ubiquitin protein was evaluated by immunohistochemistry in 49 oral melanocytic lesions, including 38 intramucosal nevi and 11 primary oral melanomas. The labeling index (LI) was assessed considering the percentage of c...

BACKGROUND Therapy with vemurafenib, an inhibitor of mutated BRAF, yields a response rate of approximately 50% in patients with metastatic melanoma harboring a BRAF V600E mutation. As an adverse effect of vemurafenib, proliferative disorders of keratinocytes, including squamous cell carcinoma, have been described. Low concentration of vemurafenib as present in the epidermis were found to activa...

Melanocytic nevi (AKA moles) are benign proliferations of melanocytes induced by the same BRAF mutation that initiates melanoma. mutant in eventually undergo growth arrest whereas melanomas do not, raising question how melanoma tumors escape and continue to progress uncontrolledly? In answering this question, we recently determined simply crossing from black mice into an isogenic albino backgro...

Introduction. The major medical concern with giant congenital melanocytic nevi CMN is high risk of developing cutaneous melanoma, leptomeningeal melanoma, and neurocutaneous melanocytosis. Case Report. A 30-year-old woman with a giant congenital melanocytic nevus covering nearly the entire right thoracodorsal region and multiple disseminated melanocytic nevi presented with neurological symptoms...
