The present study was designed to evaluate the effect of one rare sugar, D-allose, on normal human cells and cutaneous tissue, and to investigate the radiosensitizing and chemosensitizing potential of D-allose in an in vivo model of head and neck cancer. Results indicated that D-allose did not inhibit the growth of normal human fibroblasts TIG-1 cells, and no apoptotic changes were observed after D-allose and D-glucose treatment. The mRNA expression levels of thioredoxin interacting protein (TXNIP) in TIG-1 cells after D-allose treatment increased by 2-fold (50...

Breast cancer is the most common cause of skin metastases in women. The probability of their occurrence ranges from about 5% in the entire population to as much as 30% in the late stages of the disease. Although rarely life-threatening, they have a major impact on the quality of life of patients with this diagnosis, being the cause of pain, effusion, ulceration, infection, and psychological discomfort. Available methods of treatment, both local and systemic, often fail to provide adequate control of the disease...

Escin, as an internally applied anti-inflammatory agent, has been widely used in the treatment of inflammation and edema resulting from trauma or operation in the clinic. However, the effect of its external use on cutaneous inflammation and edema remains unexplored. In the present study, the anti-inflammatory and anti-edematous effects of external use of escin were studied in carrageenan-induced paw edema and histamine-induced capillary permeability in rats, paraxylene-induced ear swelling in mice, and cotton pellet-induced granuloma in rats...

REVIEW
Starling Tolliver, Jaqueline Graham, Benjamin H Kaffenberger
Necrolytic migratory erythema (NME) is a rare skin disorder that is a cutaneous manifestation of the glucagonoma syndrome. It presents with annular eruptions of migrating erythematous papules and plaques with superficial epidermal necrosis, central flaccid bullae, and crusted erosions located primarily in the intertriginous areas. Treatment with the long-acting somatostatin analog Octreotide is a potential therapy to help ameliorate skin symptoms. We present a case of a patient with a 1-year history of a pancreatic glucagonoma that developed an ulcerated, plaque-like, weeping rash over multiple areas of their body despite current treatment with Octreotide and stable pancreatic tumor staging...

BACKGROUND AND OBJECTIVES: The standard treatment for cutaneous squamous cell carcinoma (cSCC) is wide local excision (WLE). Incomplete tumor excision is associated with increased recurrence rates and mortality risk. Risk factors for positive margins after WLE of cSCC has been examined in only a few studies. We sought to assess the influence of several clinicopathological factors on margin status in the largest cSCC population to date. METHODS: We performed a retrospective review of records at two skin cancer clinics identifying patients with biopsy-proven cSCC who underwent WLE...

Paraneoplastic Pemphigus (PNP) is a rare and often fatal autoimmune mucocutaneous blistering disease associated with an underlying malignancy. It is thought to be caused by antibodies to tumor antigenscross-reacting with epithelial antigens, specifically desmosomal and hemidesmosomal antigens. There are at least five clinical morphologic variants of PNP, with the earliest and most consistent finding beingsevere stomatitis. Diagnosis of PNP requires direct immunofluorescence of perilesional skin and indirect immunofluorescence...

Bazex syndrome (BS) is a rare paraneoplastic syndrome most frequently associated with squamous cell carcinomas of the upper aerodigestive tractand other tumours. Characteristically, cutaneous lesions precede the diagnosis of malignancy. We report a 72-year-old patient with 1-year history of acral dermatitis. The diagnosis of BS was based on the presence of psoriasiform acral dermatitis and the evidence of two simultaneous tumors (prostate adenocarcinoma and undifferentiated carcinoma ofthe submandibular gland)...

Hereditary Nonpolyposis Colorectal Cancer (HNPCC), also known as Lynch Syndrome, is an autosomal dominant, tumor predisposing disorder usuallycaused by germline mutations in mismatch repair (MMR) genes. A subset of HNPCC, Muir-Torre Syndrome (MTS) also involves MMR gene defects and is generally accepted as a variant of HNPCC. MTS is typicallycharacterized by at least one visceral malignancy and one cutaneous neoplasm of sebaceous differentiation, with or without keratoacanthomas. In either version of the disorder, nonfunctional MMR systems lead tothe loss of genomic integrity, marked commonly by mismatches in repetitive DNA sequences, resulting in microsatellite instabilities...

Multiple myeloma oncogene 1/interferon regulatory factor 4 (MUM1/IRF-4) immunohistochemistry (IHC) is mainly used for diagnostic confirmation of plasma cell tumors (PCTs) in dogs and cats. This article describes MUM1/IRF-4 IHC expression in 20 cases of canine cutaneous histiocytoma (CH) and compares it with 10 cutaneous or mucocutaneous PCTs and 5 cutaneous histiocytic sarcomas (HSs) submitted to the same IHC protocol. All histiocytomas had strong nuclear and variable cytoplasmic immunolabeling for MUM1/IRF-4, whereas all PCTs had strong nuclear and moderate cytoplasmic immunolabeling for MUM1/IRF-4...

Segmental neurofibromatosis type 5 (NF5) is a rare form of NF, in which the cutaneous and/or neural changes are confined to one region of the body. It is often underdiagnosed or undetected due to the absence of symptoms. Inheritance of NF is different from other types of NF. Intraosseous neurofibromas are rare tumors which develop from nerves supplying the periosteum or nerves following the intraosseous course. Plexiform neurofibroma with associated intraosseous neurofibroma is extremely rare. We report a case of plexiform neurofibroma in the left axilla of a 17-year-old female with associated intraosseous neurofibroma in adjoining left humerus...

While superficial (cutaneous/subcutaneous) solitary fibrous tumor (SFT) have been described, definitive diagnosis is difficult due to overlapping features with other tumors. We describe the largest series to date of superficial SFT. For inclusion, SFT had to arise in dermis or subcutis. Twenty-six cases were identified. Patients ranged from 16 to 80 years (mean, 47 y) with a marked female predominance (19 F; 7 M). Tumors involved the head (11), thigh (7), back (3), shoulder (2), upper arm (1), ankle (1), and great toe (1)...

The tumor environment critically influences responsiveness of cancer cells to chemotherapies, most of which activate the mitochondria-regulated (intrinsic) apoptotic cascade to kill malignant cells. Especially skin tumors encounter an environment with remarkable biophysical properties. Cutaneous accumulation of Na+ locally establishes osmotic pressure gradients in vivo (hypertonicity or hyperosmotic stress), but whether cutaneous hypertonicity is a factor that modulates the responsiveness of skin cancers to therapeutic apoptosis-induction has thus far not been investigated...

BACKGROUND: The DecisionDx-Melanoma test provides prognostic information for patients with cutaneous melanoma (CM). Using formalin-fixed paraffin-embedded primary tumor tissue, the RT-PCR-based test classifies patients into a low- (Class 1) or high-risk (Class 2) category for recurrence based on expression of 31 genes. The current study was designed to assess the analytical validity of this test. METHODS: Inter-assay, inter-instrument, and inter-operator studies were performed to evaluate reliability of the 31-gene expression test results, sample stability and reagent stability...

AIMS: Merkel cell carcinoma represents poorly differentiated neuroendocrine carcinoma of cutaneous origin. In most studies the vast majority of Merkel cell carcinomas are Merkel cell polyomavirus (MCPyV)-associated. SV40 polyomavirus immunohistochemistry is typically used in the diagnosis other polyomavirus-associated diseases including tubulointerstitial nephritis and progressive multifocal leukoencephalopathy, given cross-reactivity with BK and JC polyomaviruses. MCPyV-specific immunohistochemistry is commercially available, but if SV40 immunohistochemistry also cross-reacted with MCPyV that would be advantageous from a resource-utilization perspective...

Although quantitative assessment of margins is recommended for describing excision of cutaneous malignancies, there is poor understanding of limitations associated with this technique. We described and quantified histologic artifacts in inked margins and determined the association between artifacts and variance in histologic tumor-free margin (HTFM) measurements based on a novel grading scheme applied to 50 sections of normal canine skin and 56 radial margins taken from 15 different canine mast cell tumors (MCTs)...

Blastic plasmacytoid dendritic cell neoplasm is a rare hematological malignancy derived from immature plasmacytoid dendritic cells. The tumor cells have an immature blastic appearance, and diagnosis is based on the expression of CD4, CD56 y CD123 in the absence of other lymphoid, natural killer, or myeloid antigens. The majority of affected individuals are older people with a mean age of 66 years. Male to female ratio is approximately 3:1. Common presentation includes cutaneous lesions followed by tumor dissemination...

BACKGROUND: Psoriasis is a chronic immune-mediated inflammatory disorder, with an estimated global prevalence of 2-3%. Psoriasis is associated with an impaired health-related quality of life and a substantial economic burden. Biologics, which target the pathways involved in the pathogenesis of psoriasis, represent an established therapeutic approach for moderate-to-severe plaque psoriasis, with remarkable efficacy and safety profile extensively examined and monitored. METHODS: Biological therapies currently available can be divided into three main categories: the TNFα antagonists (infliximab, adalimumab, etanercept, golimumab, certolizumab pegol), the interleukin (IL)-12/23 monoclonal antibody (ustekinumab), and IL-17 inhibitor (secukinumab, ixekizumab)...

Cutaneous melanoma, which develops from the pigment producing cells called melanocytes, is the most deadly form of skin cancer. Unlike the majority of other cancers, the incidence rates of melanoma are still on the rise and the treatment options currently available are being hindered by resistance, limited response rates and adverse toxicity. We have previously shown that an FDA approved drug leflunomide, used for rheumatoid arthritis (RA), also holds potential therapeutic value in treating melanoma especially if used in combination with the mutant BRAF inhibitor, vemurafenib...
