Melanocytic naevi are common melanocytic proliferations that may simulate the appearance of cutaneous melanoma. Naevi commonly harbour somatic mutations implicated in melanomagenesis but in most cases lack the necessary genomic alterations required for melanoma development. While the mitogen-activated protein kinase pathway and ultraviolet radiation strongly contribute to naevogenesis, the somatic mutational landscape of dermoscopic naevus subsets distinguishes some of the molecular hallmarks of naevi in relation to melanoma...

Genes in the S100 family are abnormally expressed in a variety of tumor cells and are associated with clinical pathology, but their prognostic value in melanoma patients has not yet been fully elucidated. In this study, we extracted and profiled S100 family mRNA expression data and corresponding clinical data from the Gene Expression Omnibus database to analyze how expression of these genes correlates with clinical pathology. Compared with normal skin, S100A1, S100A13, and S100B were expressed at significantly higher levels in melanoma samples...

BACKGROUND: Rhabdoid meningiomas are rare World Health Organization grade 3 tumors that tend to follow an aggressive course, with an increased likelihood for local recurrence, remote metastasis, and cerebrospinal fluid dissemination. Genetic testing has found certain genes associated with reduced time to tumor recurrence. BAP1 (BRCA1-associated protein 1) is a tumor suppressor gene that is associated with multiple tumors, including rhabdoid meningiomas. CASE DESCRIPTION: We present a case of a pediatric patient who presented with a rhabdoid meningioma occurring in the right tentorium and invading multiple venous structures, including the right jugular vein...

Background: Clinical trials have recently evaluated safety and efficacy of neoadjuvant therapy among patients with surgically resectable regional melanoma metastases. To capture informative prognostic data connected to pathological response in such trials, it is critical to standardize pathologic assessment and reporting of tumor response after this treatment. Methods: The International Neoadjuvant Melanoma Consortium meetings in 2016 and 2017 assembled pathologists from academic centers to develop consensus guidelines for pathologic examination and reporting of surgical specimens from AJCC (8th edition) stage IIIB/C/D or oligometastatic stage IV melanoma patients treated with neoadjuvant-targeted or immune therapy...

PURPOSE: The face is an unfortunate location for any type of tumor - malignant or not - with significant esthetic and functional outcomes. To reconstruct a facial defect may seem simple, but can be rather complicated. The aim of this study is to analyze and discuss our results in order to conclude with specific surgical strategies correlated with the morphopathological results. The most important objective for us is to offer the highest level of expertise to our patients and to prove that the symbiosis between the surgical treatment and the work of the Department of Morphopathology is essential in order to maximize the quality of medical care provided for our patients...

The transcription factor SOX10 mediates the differentiation of neural crest-derived cells, and SOX10 by immunohistochemistry(IHC) is used primarily for the diagnosis of melanoma. SOX10 expression has been previously documented in benign breast myoepithelial cells. However there is limited literature on its expression in triple negative breast carcinoma(TNBC). The aim was to study the clinical, pathologic and molecular profiles of SOX10+ tumors in TNBC. Tissue microarrays of TNBC were evaluated for SOX10 expression in 48cases...

Purpose: Cotton Wool Spots (CWS) are a commonly described retinal finding in the posterior segment associated with an extensive number of systemic diseases. The appearance of a CWS in the setting of glaucoma has rarely been reported and has not been correlated with pathology to localized loss of the nerve fiber layer previously. In this case report, we augment a previous report of an 18 year old female with a diagnosis of low grade ciliary body melanoma. This patient experienced eventual mechanical angle closure with a CWS appearing in the posterior pole in the setting of acute elevation of intraocular pressure (IOP)...
