With "checkpoint inhibitors" targeting PD1/PD-1-ligands or CTLA-4/CD28 pathways, immunotherapy has profoundly modified therapeutic strategies in oncology. First approved in refractory metastatic neoplasms (melanoma and lung adenocarcinoma), it is now being tested broadly in other cancers and/or as adjuvant treatment. For a significant proportion of patients, immunotherapy is responsible for "immunological" events, identified as Immune-Related Adverse Events (irAEs). Owing to the increasing number of prescriptions, identification and management of specific immunological side effects is crucial and requires close collaboration between oncologists and internists and/or other organ specialists...

BACKGROUND: Among older patients, melanoma in general presents biological features related to a more aggressive biology, such as more locally advanced tumor. Management of melanoma in elderly may be difficult, mainly due to comorbidities. We report the experience of the Melanoma Unit of University Hospital ASST Spedali Civili di Brescia, Italy. METHODS: Study subjects were drawn from 3444 patients with histological confirmed melanoma. Data were extracted from electronic database of the Melanoma Unit of University Hospital ASST Spedali Civili of Brescia, Italy...

The presence of psychological distress has a negative impact not only on cancer patients' quality of life but also on the course of the disease, with slower recovery and increased morbidity. These issues are of particular importance in melanoma patients (MP), who remain at risk of disease progression for many years after diagnosis. This study aimed to investigate psychological distress, coping strategies, and their possible relationships with demographic-clinical features in patients with early-stage melanoma in follow-up...

Isolated pleural metastasis with pleural effusion is a rare occurrence in malignant melanoma. We report an unusual case of a patient with chronic lymphocytic leukemia (CLL) and recurrent pleural effusions. The pleural fluid cytology and immunohistochemistry profile were consistent with the diagnosis of CLL. However, chemotherapy with pentostatin, cyclophosphamide, and rituximab did not result in any meaningful clinical response. A video-assisted thoracoscopic surgery and biopsy of the affected nodular parietal layer of the pleura were consistent with malignant melanoma...

Uveal melanoma (UM) is the most common intraocular malignancy and arises from melanocytes in the iris, ciliary body, or choroid. Early diagnosis and local treatment is crucial, as survival correlates with primary tumor size. However, approximately 50% of patients will develop metastatic disease with 6-12 months' survival from metastatic diagnosis. Genomic analyses have led to the development of gene-expression profiles that effectively predict metastatic progression; unfortunately, no adjuvant therapy has been shown to prolong survival to date...

Melanoma is the most aggressive type of skin cancer and efforts to improve the diagnosis of this neoplasia are largely based on the use of cell lines. Metabolomics is currently undergoing great advancements towards its use to screening for disease biomarkers. Although NMR metabolomics includes both 1D and 2D methodologies, there is a lack of data in the literature regarding heteronuclear 2D NMR assignments of the metabolome from eukaryotic cell lines. The present study applied NMR-based metabolomics strategies to characterize aqueous and lipid extracts from murine melanocytes and melanoma cell lines with distinct tumorigenic potential, successfully obtaining fingerprints of the metabolites from the extracts of the cell lines by means of 2D NMR HSQC correlation maps...

A case of malignant melanoma in a sheep's brain is described for the first time. In a 7-month-old sheep that had been euthanized due to ataxia, post-mortem and histopathologic examinations were performed. Both the brain and the calvarium were heavily infiltrated with neoplastic tissue. Metastases were found in the liver and kidneys. Histomorphology confirmed the gross pathologic impression of malignancy. Congenital melanosis, which is regularly present in the meninx of sheep, could have been the origin of the malignant melanoma in the present case...

Malignant melanoma (MM) in the female genital tract accounts for less than 2% of all melanomas, and the vast majority associated occur in the vulva and vagina. Primary MM of the uterine cervix is extremely rare and its prognosis is very poor. We report a case of primary MM of the cervix with dissemination throughout the vaginal wall. A 66-year-old woman presented with postmenopausal bleeding. Gynecologic examination demonstrated a 2 cm polypoid blackish-pigmented tumor on the cervix with multiple small blackish-pigmented lesions throughout the vaginal wall...

Importance: Understanding the contribution of the ugly duckling sign (a nevus that is obviously different from the others in a given individual) in intrapatient comparative analysis (IPCA) of nevi may help improve the detection of melanoma. Objectives: To assess the agreement of dermatologists on identification of the ugly duckling sign and estimate the contribution of IPCA to the diagnosis of melanoma. Design, Setting, and Participants: The same 2089 digital images of the nevi of a sample of 80 patients (mean age, 42 years [range, 19-80 years]; 33 men and 47 women), as well as 766 dermoscopic images from a subset of 30 patients (mean age, 40 years [range, 21-75 years]; 12 men and 18 women), were randomly presented to the same 9 dermatologists for blinded assessment from September 22, 2011, to April 1, 2013...

The current strategies for early diagnosis result at the moment insufficient to make further progresses in the fight against the melanoma. To reduce mortality from this tumour is need to reach people not reached until now by screening activity. The well-known risk factors are still effective but they have to be implemented by other variables at risk like sex and age. The over 50 years should be considerer at risk, independently from other features. Renewed messages should be addressed to population and General Practitioner...

Digital dermoscopy (DD) follow up is a useful strategy for monitoring patients at high risk of melanoma. Reflectance confocal microscopy (RCM) is a valuable second-level examination after dermoscopy for the evaluation of difficult to diagnose lesions. The aim of this study was to assess the value of RCM in routine DD monitoring of patients at high risk of melanoma. In this prospective study, performed over 22 months, changing melanocytic lesions were detected by DD and excised. RCM imaging was performed before surgical excision of all the lesions, and histopathology used as the gold standard diagnostic test...

BACKGROUND: Optical coherence tomography (OCT) is a real-time non-invasive imaging tool, introduced in dermatology in the late 1990s. OCT uses near-infrared light impulses to produce images which can be displayed in cross-sectional and en-face mode. The technique has been used to image skin diseases especially non-melanoma skin cancer including actinic keratosis (AK). Morphological characteristics of AK can be visualized in OCT images and can be used for diagnosis as well as disease monitoring...

BACKGROUND: Immune checkpoint blockade therapy (ICBT) for the treatment of melanoma has led to an important improvement of overall survival in advanced stage patients. However, secondary cutaneous maculopapular eruptions (CMPEs) are frequent and remain poorly characterized. METHODS: We performed a retrospective analysis of melanoma patients from our institution who developed CMPEs during ICBT. Clinical information was retrieved, and histopathological and immunohistochemical characterization was performed by two pathologists...

Melanoma is the most common cancer in women during their reproductive years and kills more young Australians than any other single cancer. Care of women whose pregnancy is complicated by a diagnosis of malignancy is complex. The risk of delaying treatment to the mother, the short-term and long-term risks of premature delivery to the child, and the immediate risks to the foetus and long-term risks to the child of maternal treatment with surgery, radiotherapy or medical therapies must be considered.

There are reported cases of diphencyprone used in treating cutaneous metastases of melanoma. Here, we report a patient with previous primary melanoma on his left back treated with surgical excision and lymphadenectomy, followed by radiotherapy for the recurrent tumor on the primary site. Despite radiotherapy and treatment with dabrafenib and trametinib, in-transit metastases have developed and topical diphencyprone was applied to these metastases. Six weeks later, the patient developed fever and a spreading erythematous tender indurated plaque covering the left side of the body including axillae, back, and flank, clinically suggestive of cellulitis...

BACKGROUND: An early and prompt NAM diagnosis is associated with less invasive surgical procedures and a better patient's prognosis. The diagnostic delay may be related both to the clinical misinterpretations and to errors in the diagnosing process. Biopsy techniques have been adequately describe by nail experts, but the two main problems in the correct choice of the biopsy are probably related to the difficulty in performing surgery in the nail unit and the risk of permanent nail dystrophy...

Cutaneous squamous cell carcinoma (cSCC) is the second most common non-melanoma skin cancer worldwide. Today, cSCC is diagnosed by visual inspection followed by invasive skin biopsy. There is a need to develop non-invasive diagnostic tools to achieve early and accurate detection. Photoacoustic imaging (PAI) possesses high ultrasonic resolution and strong optical contrast at new depths (<1-5 cm). Together with exogenous contrast agents, PAI has found promising use in various tumors in living subjects. The expression of integrin αvβ6 is significantly up-regulated in cSCC...
