Anderson-Fabry disease is an X-linked lysosomal storage disorder caused by mutations in the GLA gene that result in deficiency of the enzyme alpha-galactosidase A. The worldwide incidence of Fabry's disease is reported to be in the range of 1 in 40,000-117,000, although this value may be a significant underestimate given under recognition of symptoms and delayed or missed diagnosis. Deficiency in alpha-galactosidase A causes an accumulation of neutral glycosphingolipids such as globotriaosylceramide (Gb3) in lysosomes within various tissues including the vascular endothelium, kidneys, heart, eyes, skin and nervous system...

INTRODUCTION: The aim of surgical management of benign facial skin lumps is to remove the lesion in its entirety, with minimal damage to adjacent tissue structures, while maintaining facial aesthetics. A method to achieve these goals is to remove peri-oral lesions in the labial and buccal zones via an intra-oral approach. We report an extended cases series of facial skin lumps that were excised using an intra-oral approach. METHODS: A retrospective analysis was performed on all patients who underwent excisions of benign cutaneous lesions on the face via an intra-oral approach...

With globalization and widespread immigration, physicians increasingly encounter patients from varying backgrounds and diverse customs. Although certain cultural practices are widely performed, there is limited medical literature describing their dermatologic and systemic effects and complications. Population diversity and sharing of traditions make it increasingly important for dermatologists to understand the role of cultural practices and recognize physiologic and pathologic sequelae. In addition, dermatologists are often adjured to assess skin findings that may be mistaken for abuse...

Actinic keratosis (AK) is a very common skin disease caused by chronic sun exposure. AKs have historically been characterized as being "precancerous" or "premalignant." It is true that these lesions do not possess metastatic potential, because they are confined to the epidermis, but it is not accurate to deem them "premalignant." AK qualifies as a malignant neoplasm, because it also fulfills criteria for malignancy in classic pathology, namely, the capability, or potential, to kill by either destruction of tissue locally or by metastasis widely...

The pharmacological modulation of collagen turnover is a strategy potentially useful in different skin conditions. The serine protease inhibitor Serpin A1 and portions of its C-terminal region have been investigated as collagen modulators. To clarify the mechanisms by which the C-terminal 409-418 peptide SA1-III increases extracellular type I collagen levels, to compare its activities range with that of the originator molecule Serpin A1, and to evaluate its efficacy in primary cultures from adult and aged human subjects...

Piscine mycobacteriosis is a lethal disease with zoonotic potential, found worldwide in both fresh and marine fish. More than 20 strains of Mycobacterium spp. are known to persist in fish so far, but the pathogenicity is currently unknown for most of them. However, M. marinum is reported as one of the most pathogenic agents for fish and is involved in zoonotic cases. We examined 47 different cases from two zoological gardens, where fish tuberculosis was identified or previously suspected during the last ten years...

Chordomas are rare, slow-growing, locally aggressive bone tumors arising from embryonic remnants of the notochord. Distant metastases most commonly involve the lung, liver, axial skeleton, skin, and lymph nodes. Humeral metastases are extremely rare. We report the case of a recurrent chordoma with humeral metastasis, complicated with pathologic fracture. Fluorine-18 fluorodeoxyglucose positron emission tomography-computed tomography revealed multiple hypermetabolic skeletal lesions, corresponding to the symptoms...

Calciphylaxis is a poorly understood condition involving vascular calcification and thrombosis that leads to skin necrosis. Unfortunately, a noninvasive definitive test for calciphylaxis does not currently exist, and diagnosis relies on clinical symptoms and risk factors. Imaging can help guide diagnosis of this rare disorder. We present a pathology-proven case of calciphylaxis and the corresponding imaging findings seen on bone scintigraphy.

BACKGROUND: Allergic contact dermatitis (ACD) is a highly prevalent inflammatory disease of the skin. As a result of the complex etiology in ACD, therapeutic compounds targeting refractory pruritus in ACD lack efficacy and lead to numerous side effects. OBJECTIVE: In this study, we investigated the anti-pruritic effects of oxymatrine (OMT) and explored its mechanism of action in a mouse model of ACD. METHOD: 72 male SPF C57BL/6 mice were randomly divided into control group, ACD model group, dexamethasone positive control group (0...

Triticum vulgare has been extensively used in traditional medicine thanks to its properties of accelerating tissue repair. The specific extract of Triticum vulgare manufactured by Farmaceutici Damor (TVE-DAMOR) is already present in some pharmaceutical formulations used in the treatment of decubitus ulcers, skin lesions and burns. It has been recently suggested that this Triticum vulgare extract may possess potential anti-inflammatory properties. In the light of these premises the aim of the present paper was to verify the anti-inflammatory role of TVE, using the LPS-stimulated microglia model of inflammation...

RATIONALE: Atopic dermatitis is a frequent, relapsing, chronic inflammatory skin condition with a deep negative impact on quality of life. Three are the major pathological factors driving its complex pathogenesis: the skin barrier disruption, the altered Th2 cell response and itching. Current management of the disease is often unsatisfactory, unable to induce a complete resolution of signs and symptoms or at least a significant clinical improvement with adequate patient satisfaction. PATIENT CONCERNS: We report the case of a 57-year-old man with severe chronic atopic dermatitis for at least 40 years irresponsive to traditional therapies...

Sweet syndrome is a common extraintestinal manifestation in inflammatory bowel disease (IBD). In this research, a 42-year-old man case with colon Crohn's disease is been described. After failure with two anti-TNF therapies, in treatment with azathioprim, it was decided to start a therapeutic target change to Vedolizumab due to a severe outbreak refractory to corticosteroids. 24 hours after the infusion of the new drug, skin lesions appear along with leukocytes with neutrophilia, all suggestive of sweet syndrome later confirmed by histology...

Eosinophilia, both peripheral and in cutaneous tissue, is not a typical finding in mycosis fungoides; in fact, when faced with a lymphoeosinophilic infiltrate, mycosis fungoides is often not part of initial differential considerations. However, eosinophilia has been described in certain subtypes of mycosis fungoides, namely, in folliculotropic mycosis fungoides. We describe three challenging cases of folliculotropic mycosis fungoides presenting with varied clinical morphologies and a dense lymphoeosinophilic infiltrate and/or severe hypereosinophilia that obscured the final diagnosis for years...

Myeloid cells can be beneficial as well as harmful in tissue regenerative responses. The molecular mechanisms by which myeloid cells control this critical decision of the immune system are not well understood. Using two different models of physiological acute or pathological chronic skin damage, in this study we identified myeloid cell-restricted STAT3 signaling as important and an injury context-dependent regulator of skin fibrosis. Targeted disruption of STAT3 signaling in myeloid cells significantly accelerated development of pathological skin fibrosis in a model of chronic bleomycin-induced tissue injury, whereas the impact on wound closure dynamics and quality of healing after acute excision skin injury was minor...

BACKGROUND: Low C-C chemokine receptor 1 (CCR1) and interleukin (IL)-10 expression is associated with risk of Behçet's disease (BD). The objective of the present study was to clarify the pathological roles of CCR1 and IL10 loci identified by previous BD genome-wide association studies (GWASs). METHODS: M1 and M2 macrophages (Mφ) were differentiated with granulocyte-macrophage colony-stimulating factor or macrophage colony-stimulating factor (M-CSF) from peripheral monocytes of healthy control subjects (HC) and patients with BD...

BACKGROUND: Early detection of various types of nonmelanoma skin cancer has been a challenge in dermatology. Noninvasive examination procedures such as optical coherence tomography (OCT) play an increasingly important role, besides the established gold standard of histological tissue sample analysis. OCT is a noninvasive, cross-sectional, real-time technique that allows conclusions to be drawn with regard to the presence of pathologies. OBJECTIVE: The objective of this study was to investigate whether it is possible to distinguish between different types of nonmelanoma skin cancer using OCT or not...

Cutaneous wound healing consists of three main phases: inflammation, re-epithelialization, and tissue remodeling. During normal wound healing, these processes are tightly regulated to allow restoration of skin function and biomechanics. In many instances, healing leads to an excess accumulation of fibrillar collagen (the principal protein found in the extracellular matrix - ECM), and the formation of scar tissue, which has compromised biomechanics, tested using ramp to failure tests, compared to normal skin (Corr and Hart, 2013 [1])...

BACKGROUND: In the future, widespread use of closed-loop infusion (artificial pancreas) systems to treat type 1 diabetes (T1D) may significantly improve glycemic control and enhance treatment flexibility. However, the infusion sets and plasters necessary for these treatments can cause dermatological complications that may hamper the spread of the new technology; few studies have investigated these complications in adults. The aim of this study was to describe the dermatological complications associated with continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM) in adults...
