Familiar melanoma

Shosuke Ito, Ludger Kolbe
Most readers of Pigment Cell & Melanoma Research are familiar with the biological/clinical aspects of pigmentation and melanoma. On the other hand, other aspects of pigmentation research, such as the application of melanin nano-particles as novel biocompatible materials, mostly escape their attention. For example, "polydopamine (PDA)" has been attracting an upsurge in interest among material scientists (175 articles published in 2015 compared with 11 in 2010), but not so much among pigment scientists despite the fact that PDA closely mimics "dopamine-melanin" as it is produced by the spontaneous oxidative polymerization of dopamine at a slightly alkaline pH...

Nodular melanoma is the most aggressive subtype of melanoma, with rapid growth rate and metastatic potential. It is usually diagnosed at a locally advanced stage (Breslow thickness <2 mm) and is therefore associated with a poor prognosis. Nodular melanoma often does not fit the classic clinical ABCD criteria, but rather the EFG rule or 3 Cs criteria. Missing the diagnosis of nodular melanoma is a dermatologist's worst nightmare, especially since nodular melanomas can have a non-alarming clinical appearance and imitate a wide range of benign lesions...

Tumors and tumorlike conditions of the anus and perianal region originate from the anal canal and anal margin or result from direct extension of tumors from adjacent organs. The anatomy of the anal canal is complex, and its different histologic characteristics can lead to diverse pathologic conditions. The anal canal extends from the anorectal junction to the anal verge. The World Health Organization classification of anal canal tumors includes (a) anal intraepithelial neoplasia, the precursor of squamous cell carcinoma (SCC), and (b) invasive tumors...

Participants first became familiar with an image showing moderate symptoms of the skin cancer melanoma. In a generalization test, they indicated whether images showing more and less pronounced symptoms were "like the original." Some groups (cancer context) were told that the images depicted melanoma and that the disease is deadly unless detected early. Control groups were not told what the images depicted. For control groups, generalization gradients were fairly typical of what is normally reported in the generalization literature, but for cancer context groups, gradients were shifted such that highly symptomatic moles were identified as "like the original" more than normal and subtly symptomatic ones were endorsed less than normal...

Immunotherapy for advanced melanoma has progressed dramatically in the last five years with the approval of immune checkpoint inhibitors targeting cytotoxic T lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1). Inhibition of these targets can break cancer-immune tolerance and result in durable objective responses with significantly improved tolerability over cytokine-based immunotherapy. Ipilimumab is an inhibitor of CTLA-4 and the first-in-class immune checkpoint inhibitor to demonstrate an improvement in overall survival in melanoma...

BACKGROUND: Volatile organic compounds (VOCs) are continuously released by the body during normal metabolic processes, but their profiles change in the presence of cancer, offering an objective, non-invasive approach to diagnosis. Robust evidence that invasive melanoma in-vivo emits a characteristic VOC signature is currently lacking. OBJECTIVE: To conduct a canine olfactory, proof of principle study, to investigate whether VOCs captured from the surface of invasive melanoma are distinguishable from those of basal cell carcinoma (BCC), benign naevi and healthy skin in-vivo...

The anti-programmed cell death-1 monoclonal antibody (mab), nivolumab has recently been approved for the treatment of unresectable or metastatic malignant melanoma and non-small-cell lung cancers in Japan. Ipilimumab, an anti-cytotoxic T lymphocyte antigen-4 mab for malignant melanoma that was approved earlier than nivolumab in Western countries, is known to frequently cause endocrine immune-related adverse events such as hypophysitis and thyroid dysfunction. We herein report a patient with advanced melanoma who appeared to develop hypophysitis as a consequence of the inhibition of PD-1 by nivolumab...

In the last few years, melanoma treatment has been revolutionized by the development of immune checkpoint-blocking antibodies or immune checkpoint inhibitors including ipilimumab, vemurafenib, dabrafenib, trametinib, nivolumab, and pembrolizumab. Although they have shown promising results, they also have caused multiple adverse events (AEs), particularly immune-related AEs (irAEs). Specialists should be familiar with these AEs.

Until recently, chemotherapy for metastatic melanoma had disappointing results. The identification of immune checkpoints such as CTLA-4 and PD-1/PD-L1 has led to the development of an array of monoclonal antibodies (Mabs). These immunologic approaches against tumoral cells come with a novel kind of side effects that the clinician needs to be familiarized with. Herein, we report for the first time a case of organizing pneumonia, based on imaging and cytological analyses of bronchoalveolar lavage, possibly associated with the use of pembrolizumab, an anti-PD-1 Mab recently approved for the treatment of metastatic melanoma...

Conjunctival melanoma is a rare malignant tumour of the eye. Its diagnosis represents a challenge for general pathologists due to low exposure to ocular biopsies and a broad differential diagnosis. In addition, conjunctival samples are often small and are associated with a high frequency of artefacts due to their processing. Here, we present the first case to date of a traumatic iridial extrusion masquerading as a conjunctival melanocytic neoplasm. An 83-year-old Asian man presented with a conjunctival-pigmented nodule surrounded by an area of diffuse pigmentation...

Although most breast spindle cell lesions (BSCLs) are rare, they constitute a wide spectrum of diseases, ranging from reactive processes to aggressive malignant tumours. Despite their varied histogenesis and behaviour, some lesions show an overlap of morphological features, making accurate diagnosis a challenging task, particularly in needle core biopsies. Clinical history and immunohistochemistry can help in making a correct diagnosis in morphologically challenging cases. To make an accurate diagnosis, it is important to maintain a wide differential diagnosis and be familiar with the diverse morphological appearances of these different entities...

BACKGROUND: Melanoma is an immunogenic tumor and the presence of T-cell infiltrates within melanoma lesions may correlated with longer patient survival. Psoriasis is a chronic immune- mediated inflammatory disease, in which the role of T-cells is well established. OBJECTIVES: The aim of our prospective pilot study was to investigate the relationship between melanoma and psoriasis examining 3 groups of patients: Melanoma-group (MG), Psoriasis-group (PG) and Control-group (CG)...

Although primary breast cancer is the most common malignancy identified by breast imaging, extramammary malignancies may also rarely be encountered. These uncommon lesions may reflect primary neoplasms of nonmammary origin as well as secondary metastatic lesions, and include lymphoma, melanoma, neuroendocrine tumors, gastrointestinal tract malignancies, and angiosarcoma among other entities. Malignant extramammary breast lesions may be encountered during routine mammographic screening, identified during the diagnostic evaluation of a palpable breast abnormality, or may be detected incidentally during imaging of other organs of interest...

BACKGROUND: Cutaneous melanoma is often characterized by its pigmented appearance; however, up to 8.1% of such lesions contain little or no pigmentation. Amelanotic melanomas, lesions devoid of visible pigment, present a diagnostic quandary because they can masquerade as many other skin pathologies. Recognizing amelanotic melanoma is even more clinically challenging when it is first detected as a metastasis to the secondary tissue. METHODS: We report a rare case of metastasis of an amelanotic melanoma to the parotid gland...
