Apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) is an important adaptor protein for inflammasome activation, mediating the secretion of protumorigenic innate cytokines. However, ASC is also known to trigger apoptosis in tumor cells, acting as a tumor-suppressor gene, which is lost in several human cancers. The aim of this study was to evaluate the clinical significance of ASC in human cutaneous squamous cell carcinoma (SCC). Initially, ASC expression was immunohistochemically evaluated in non-metastic and metastatic SCC...

Erythema annulare centrifugum (EAC) is a clinical reaction pattern that includes lupus erythematosus, spongiotic dermatitis (particularly pityriasis rosea), pseudolymphoma and cutaneous B-cell lymphoma. However, it can be the result of cutaneous metastasis by an internal carcinoma. We present the case of a 38-year-old woman with bilateral inflammatory breast cancer following multimodal therapy. After chemotherapy, the patient developed EAC on her back, clinically suspect of subacute cutaneous lupus erythematosus...

Primary cutaneous anaplastic large cell lymphoma (PCALCL) is a rare CD30(+) lymphoproliferative disorder with excellent outcomes reported despite frequent cutaneous relapses. Limited information exists on the development of systemic lymphoma. The British Columbia Cancer Agency (BCCA) Lymphoid Cancer Database was searched to identify all adults diagnosed with PCALCL from 1993 to 2013. From 2005, the BCCA endorsed radiotherapy (RT) alone for limited stage with data failing to support chemotherapy. Forty-seven patients were identified with a male predominance (n = 31, 66%), median age of 64 years and predominantly limited stage (n = 40, 85%)...

BACKGROUND: An anti-programmed cell death protein 1 monoclonal antibody, nivolumab, is one of the most effective drugs for advanced melanoma. Tumor cell-derived or immune cell-derived markers and clinical predictors such as serum lactate dehydrogenase (LDH) and cutaneous adverse events, have already been described as prognostic factors for advanced melanoma treated with nivolumab. We sought to identify further clinical predictors that can be determined in routine clinical practice. METHODS: We retrospectively analyzed clinical findings of 98 consecutive patients with unresectable stage III or IV melanoma treated with nivolumab, at the National Cancer Center Hospital or at Keio University Hospital, in Tokyo, Japan, between July 2014 and July 2016...

Melanoma is a malignant neoplasm of melanocytes that can metastasize to every organ of the body, but metastasis to the oral cavity is uncommon. We describe a case of metastatic malignant melanoma to the mandible in a 33-years-old woman. The patient had a 2 cm × 4 cm firm, ulcerated nodule, distal to the second mandibular right molar. Incisional biopsy revealed epithelioid cells and immunohistochemistry was positive for HMB-45, S-100 protein and vimentin. The patient was referred to the local cancer hospital for treatment but died 3 months later...

Cancer prevention through intake of biologically active natural products appears to be an accessible way to reduce the risk of cancer. Diallyl disulfide (DADS), a major garlic derivative, has exhibited potential role in cancer therapy. The study is aimed to evaluate the prophylactic effect of DADS in chemically induced mouse skin carcinogenesis and investigate the molecular targets mediated by DADS. Two-stage chemically induced carcinogenesis model by cutaneous application of DMBA and subsequent TPA was established to study the prophylactic effect of DADS...

BACKGROUND: Basal cell carcinoma (BCC) is the most common malignancy in the United States. Most BCCs occur on cutaneous surfaces, but rare cases on the mucosal lip have also been documented. Because only a small number of mucosal BCC (mBCC) cases have been reported, data on their clinical characteristics and management are limited. OBJECTIVE: To perform an updated literature review of the management of mBCCs on the lip. METHODS: A comprehensive literature review was conducted through a search of the PubMed database with the key phrases "mucosal basal cell carcinoma," "basal cell carcinoma mucosa," and "basal cell carcinoma lip mucosa...

We evaluated the potential utility of hydrogels for delivery of the photosensitizing agents 5-aminolevulinic acid (ALA) and hematoporphyrin monomethyl ether (HMME) to rectal tumors. Hydrogel suppositories containing ALA or HMME were administered to the rectal cavity of BALB/c mice bearing subcutaneous tumors of SW837 rectal carcinoma cells. For comparison, ALA and HMME were also administered by three common photosensitizer delivery routes; local administration to the skin and intratumoral or intravenous injection...

BACKGROUND: Systemic sclerosis (SSc) is a complex autoimmune disease characterized by vascular alterations and autoimmune activation leading to widespread organ fibrosis. At the early stage of disease when organ involvement and extent of disease are emerging, mast cells may have some role, as implied by both symptoms and histologic evidence. CASE PRESENTATION: A female patient diagnosed with cutaneous mastocytosis experienced the onset of systemic sclerosis after 15 years followed by the switch of mastocytosis to the systemic phenotype...

BACKGROUND: The patient and observer scar assessment scale (POSAS) recently emerged as a promising method, reflecting both observer's and patient's opinions in evaluating scar. This tool was shown to be consistent and reliable in burn scar assessment, but it has not been tested in the setting of skin graft scar in skin cancer patients. OBJECTIVE: To evaluate facial skin graft scar applied to POSAS and to compare with objective scar assessment tools. METHODS: Twenty three patients, who diagnosed with facial cutaneous malignancy and transplanted skin after Mohs micrographic surgery, were recruited...

Photodermatoses associated with defective DNA repair are a group of photosensitive hereditary skin disorders. In this review, we focus on diseases and syndromes with defective nucleotide excision repair that are not accompanied by an increased risk of cutaneous malignancies despite having photosensitivity. Specifically, the gene mutations and transcription defects, epidemiology, and clinical features of Cockayne syndrome, cerebro-oculo-facial-skeletal syndrome, ultraviolet-sensitive syndrome, and trichothiodystrophy will be discussed...

Hereditary photodermatoses are a spectrum of rare photosensitive disorders that are often caused by genetic deficiency or malfunction of various components of the DNA repair pathway. This results clinically in extreme photosensitivity, with many syndromes exhibiting an increased risk of cutaneous malignancies. This review will focus specifically on the syndromes with malignant potential, including xeroderma pigmentosum, Bloom syndrome, and Rothmund-Thomson syndrome. The typical phenotypic findings of each disorder will be examined and contrasted, including noncutaneous identifiers to aid in diagnosis...

BACKGROUND: Mucosal melanomas are rare, poorly understood neoplasms without a consensus standard of care. OBJECTIVE: We sought to define mucosal melanoma tumor characteristics and the racial/ethnic attributes of patients with mucosal melanomas. METHODS: We analyzed 130,920 cutaneous melanomas and 1919 mucosal melanomas recorded in the population-based California Cancer Registry from 1988 to 2013. RESULTS: Although only 1% of melanomas occurring in nonHispanic whites were mucosal, other racial/ethnic groups had a higher proportion of mucosal melanomas (15% for Asian/Pacific Islanders, 9% for nonHispanic blacks, and 4% for Hispanics)...

Global temperatures continue to rise, reaching new records almost every year this decade. Although the causes are debated, climate change is a reality. Consequences of climate change include melting of the arctic ice cap, rising of sea levels, changes in precipitation patterns, and increased severe weather events. This article updates dermatologists about the effects of climate change on the epidemiology and geographic ranges of selected skin diseases in North America. Although globalization, travel, and trade are also important to changing disease and vector patterns, climate change creates favorable habitats and expanded access to immunologically naïve hosts...

The evidence that PITX1 (pituitary homeobox 1) is a significant tumor suppressor in human cancer remains largely circumstantial, but it clearly warrants further study as little is known about the tumor-inhibitory roles of PITX1 in cutaneous malignant melanoma. The aims of this study were to investigate PITX1 gene expression in patients with cutaneous malignant melanoma and to evaluate its potential relevance to clinicopathological characteristics and tumor cell proliferation. Clinicopathological findings of patients with cutaneous malignant melanoma were analyzed retrospectively...
