Social comparison processes, narrative mapping and their shaping of the cancer experience: a case study of an elite athlete.

2011

Drawing on data generated by life history interviews and fieldwork observations we illuminate the ways in which a young elite athlete named David (a pseudonym) gave meaning to his experiences of cancer that eventually led to his death. Central to this process were the ways in which David utilized both social comparisons and a narrative map provided by the published autobiography of Lance Armstrong (2000). Our analysis reveals the selective manner in which social comparison processes operated around the following key dimensions: mental attitude to treatment; the sporting body; the ageing body; and physical appearance. The manner in which different comparison targets were chosen, the ways in…

What links BRAF to the heart function? new insights from the cardiotoxicity of BRAF inhibitors in cancer treatment

2015

The RAS-related signalling cascade has a fundamental role in cell. It activates differentiation and survival. It is particularly important one of its molecules, B-RAF. B-RAF has been a central point for research, especially in melanoma. Indeed, it lacked effective therapeutic weapons since the early years of its study. Molecules targeting B-RAF have been developed. Nowadays, two classes of molecules are approved by FDA. Multi-target molecules, such as Sorafenib and Regorafenib, and selective molecules, such as Vemurafenib and Dabrafenib. Many other molecules are still under investigation. Most of them are studied in phase 1 trials. Clinical studies correlate B-RAF inhibitors and QT prolonga…

Psycho‐oncological care of melanoma patients in certified skin cancer centers

2017

Background The establishment und certification of skin cancer centers (SCCs) in compliance with requirements issued by the German Cancer Society play a key role for quality-assured treatment of skin cancer patients. These requirements also call for the implementation of a qualified psycho-oncology program. When planning the present study, we assumed site-specific differences in the way such programs were implemented at various SCCs. Methods In 2014, we conducted a cross-sectional survey of all SCCs certified at the time (n = 43), in which these institutions were asked to provide information on the structural and process quality of their psycho-oncology programs. Results Overall, 81.4 % of c…

Protocolo de diagnóstico histológico para muestras de pacientes con melanoma cutáneo. Documento de consenso de la SEAP y la AEDV para el Registro Nac…

2021

This article describes a proposed protocol for the histologic diagnosis of cutaneous melanoma developed for the National Cutaneous Melanoma Registry managed by the Spanish Academy of Dermatology and Venereology (AEDV). Following a review of the literature, 36 variables relating to primary tumors, sentinel lymph nodes, and lymph node dissection were evaluated using the modified Delphi method by a panel of 8 specialists (including 7 pathologists). Consensus was reached on the 30 variables that should be included in all pathology reports for cutaneous melanoma and submitted to the Melanoma Registry. This list can also serve as a model to guide routine reporting in pathology departments.

Non‐invasive diagnostic techniques in pigmentary skin disorders and skin cancer

2021

Background Diagnosis of pigmentary skin disorders, pre-cancerous and cancerous skin diseases is traditionally relied on visual assessment. The most widely applied invasive diagnostic technique is the skin biopsy. There have been significant technological advances in non-invasive diagnostic methods for skin disorders. Objective The objective of this article is to discuss different non-invasive diagnostic modalities, used in the diagnosis of pigmentary skin disorders and cutaneous cancers. Methods Comprehensive literature search was performed to screen articles related to non-invasive diagnostic techniques in pigmentary skin disorders and cutaneous cancers. Articles published in journals inde…

The Man Behind the Eponym: Hans Biberstein and Follicular Hyperplasia Overlying Dermatofibroma

2009

Hans Biberstein first described the basaloid follicular hyperplasia overlying dermatofibromas in 1923 and published his extensive observations on the subject in 1931. Part of Josef Jadassohn's department in Breslau, he was forced to leave German by the National Socialist regime and spent the rest of his career in New York. After a hiatus of 30 years, the dermatopathologic literature once again began addressing his seminal finding but never gave him proper credit. We suggest Biberstein's sign as an appropriate term for basaloid follicular hyperplasia overlying a dermatofibroma and as a small tribute to a pioneer dermatopathologist.

Sentinel Node Identification in Melanoma: Current Clinical Impact, New Emerging SPECT Radiotracers and Technological Advancements. An Update of the L…

2020

Background: Melanoma is the most lethal skin cancer with a mortality rate of 262 cases per 100.000 cases. The sentinel lymph node (SLN) is the first lymph node draining the tumor. SLN biopsy is a widely accepted procedure in the clinical setting since it provides important prognostic information, which helps patient management, and avoids the side effects of complete lymph node dissection. The rationale of identifying and removing the SLN relies on the low probability of subsequent metastatic nodes in case of a negative histological exam performed in the SLN. Discussion: Recently, new analytical approaches, based on the evaluation of scintigraphic images are also exploring the possibility …

Cerebriform sebaceous nevus: a subtype of organoid nevus due to specific postzygotic FGFR2 mutations.

2021

Background Postzygotic mutations in FGFR2 have been identified in mosaic forms of acne, keratinocytic epidermal nevi, nevoid acanthosis nigricans / rounded and velvety epidermal nevus and in two fetuses with papillomatous pedunculated sebaceous nevus (PPSN). Objectives To determine the clinical and genetic characteristics of children with cerebriform, papillomatous, and pedunculated variants of sebaceous nevi. Methods Infants diagnosed with sebaceous nevi characterized by a cerebriform, papillomatous, and/or pedunculated morphology over a 10-year period (2010 - 2019) at three pediatric dermatology centers in Switzerland and France were included in this case series. Clinical and histological…

Minimizing the dermatoscopic morphologic overlap between basal and squamous cell carcinoma: a retrospective analysis of initially misclassified tumou…

2020

BACKGROUND Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) have well-established dermatoscopic criteria that make them relatively easy to recognize on a clinical basis. However, even with the addition of dermatoscopy, a morphologic overlap between the two tumours does exist. OBJECTIVES To analyse the dermatoscopic morphology of clinically and dermatoscopically misclassified BCCs and SCCs, to identify factors causing the erroneous clinical interpretation and, therefore, minimize the morphologic overlap between BCC and SCC. METHODS Retrospective study including histopathologically diagnosed BCCs or SCCs that had been clinically inversely diagnosed. Their dermatoscopic images were…
