Abstract
It is well-established that tumour necrosis factor (TNF)-α-antagonist regimens are advisable for the control of moderate to severe psoriasis; however the application of these agents is associated with increased risk of TB reactivation. Screening for latent tuberculosis infection (LTBI) is indispensable prior to treatment inception in order to diminish the risk of active TB. Although tuberculin skin test (TST) still represents a useful tool for LTBI detection, it is difficult to be performed and read in patients with extensive psoriatic lesions. In this paper, we report the case of a 65-year-old male with severe psoriasis, who was evaluated by an interferon-gamma release assay (IGRA) for LTBI diagnosis prior to anti-TNF-α therapy. Furthermore, the physiological aspects of interferon-gamma release assays are discussed emphasizing the value of these novel immunodiagnostic tests (IGRAs) for presumable LTBI in all patients with extensive skin disorders.

Abstract
Screening for latent tuberculosis infection (LTBI) is recommended before treatment with biologics is initiated in patients with psoriasis or inflammatory bowel disease (IBD). Our objective was to evaluate the effect of underlying disease (psoriasis or IBD) on the risk of LTBI diagnosis prior to anti-tumor necrosis factor-alpha (TNF-α) therapy. During a two-year period LTBI diagnosis rate was compared in consecutive patients with psoriasis or IBD (Crohn's disease or ulcerative colitis). IBD patients (n = 33) had significantly smaller tuberculin skin testing compared to psoriasis patients (n = 30) (p = 0.007). Applying LTBI diagnosis guidelines resulted in more psoriasis (50%) than IBD patients (24.2%) receiving treatment for LTBI prior to onset of anti-TNF-α treatment (p = 0.04). In conclusion, current recommendations for LTBI diagnosis must be re-evaluated to account for the unique tuberculin hyperactive state of the skin of patients with psoriasis.

Abstract
BACKGROUND Preclinical data and reports of adverse skin reactions in patients treated with dipeptidyl peptidase-IV inhibitors (gliptins) have increased awareness towards skin-targeting side-effects of these anti-hyperglycaemic drugs. Bullous pemphigoid (BP), sometimes drug-induced, is the most commonly acquired autoimmune blistering dermatosis in western countries, typically a disease of the elderly people with significant morbidity and excess mortality. OBJECTIVE To report the development of BP in five diabetics under gliptin (4 vildagliptin, 1 sitagliptin) plus metformin in fixed-dose drug combinations. CASE REPORTS From March to August 2010 six out of nine newly diagnosed BP patients in our Department were type 2 diabetics. Five of them were on gliptin plus metformin (three different trade preparations) for 2-13 months prior to BP onset. In all cases BP was controlled after withdrawal of the suspected medication and relatively mild therapeutic interventions. In two cases the eliciting role of the preceding treatment is supported by evidence at the level 'probable/likely' according to the WHO-UMC algorithm. CONCLUSIONS This is the first report of drug-induced BP as a group adverse event of the gliptins plus metformin combination therapy for glycaemia control in type 2 diabetes mellitus patients.

Abstract
UNLABELLED Malassezia yeasts are found on the skin of all humans and many warm-blooded animals. In vitro they have the ability to synthesize potent ligands (indolo[3,2-b]carbazole, malassezin and indirubin) of the aryl-hydrocarbon receptor (AhR; synonym: dioxin receptor) when the sweat contained L-tryptophan is used as the single nitrogen source. The production of these AhR-ligands has been associated with pathogenic strains of a certain Malassezia species (Malassezia furfur) but recent evidence shows that this property is widely distributed in almost all currently known Malassezia species. AhR is associated with carcinogenesis and the potential connection of these ubiquitous skin symbionts, and putative pathogens, with skin neoplasia should be evaluated mainly focusing on mechanisms related to the distinctive ability of the yeast to produce potent AhR ligands. HYPOTHESIS Synthesis of available pertinent data show a possible link between Malassezia produced AhR ligands and skin carcinogenesis, particularly of basal cell carcinoma (BCC). BCCs are almost exclusively observed in animal species colonized by Malassezia. In humans and animals there is overlapping in the skin regions colonized by this yeast and affected by BCC. The potent AhR ligands synthesized by pathogenic Malassezia strains could contribute to tumor promotion by: modification of the UV radiation carcinogenesis, alterations in the salvage/survival of initiated tumor cells, inhibition of cell senescence, interaction with vitamin D metabolism, promotion of immune tolerance and finally pro-carcinogenic modulation of cell cycle progression and apoptosis.

Abstract
Although a reversible, sometimes severe, drug-induced thrombocytopenia is a recognized adverse drug reaction (ADR) in patients with psoriasis treated with efalizumab, definite proof for the association of thrombocytopenia with efalizumab is still lacking (currently level II evidence for ADR). We report a patient with psoriasis who had two episodes of reversible thrombocytopenia during efalizumab; the first occurred 5 months after introduction of the medication and the second 4 months after re-introduction of efalizumab for relapsing psoriasis. The development of a second episode of thrombocytopenia on re-exposure to efalizumab provides, for the first time in the literature to our knowledge, definite (level I) ADR evidence for efalizumab-induced thrombocytopenia.

Abstract
Background Eosinophilic cellulitis (Wells' syndrome) is a polyetiologic clinical entity with still obscure pathogenesis. Clinically overt toxocariasis is uncommon in adults, yet helminthozoonoses, including toxocariasis have been occasionally implicated in the pathogenesis of eosinophilic cellulitis. Case representation A 55-year-old female patient presented with a skin biopsy verified recurring febrile eosinophilic cellulitis, blood eosinophilia (42%), slight anaemia (Hct 35%), hepatosplenomegaly and positive specific anti-Toxocara canis antibodies. Toxocariasis-associated eosinophilic cellulitis was diagnosed. Already two weeks after treatment with thiabendazole the skin lesions resolved, T. canis antibody titre normalized eight months after treatment and no recurrences of eosinophilic cellulitis have been observed (for meanwhile three years). Conclusion The clinical characteristics (relapsing skin lesions, fever, hepatosplenomegaly), the laboratory features (blood eosinophilia, modest anemia, positive T. canis serology) and the clinical course after treatment, all support a causal relationship between Toxocara infection and the disease of this patient. We propose that in this context eosinophilic cellulitis must be interpreted as the leading symptom of a "skin-predominant" form of overt adult toxocariasis out of a spectrum of toxocariasis-associated febrile, "migrating-relapsing", organotropic eosinophilic inflammatory syndromes.

Abstract
BACKGROUND Either cryosurgery or topical imiquimod have been used to treat patients with lentigo maligna in cases where surgery is not feasible. METHODS We report a patient with lentigo maligna, who was treated with the combination of topical imiquimod and cryosurgery, and review the rationale, which led us to design the present combined cryo-immunological treatment modality. RESULTS Sustained clearance of lentigo maligna to date (26 months after treatment). The successful treatment of this patient was based on the following rationale: A cryosurgery session during continuing imiquimod application may: (i) reinforce apoptosis of tumor cells; (ii) strengthen antiangiogenesis in the treated tumor; and (iii) build-up a potent tumor-destructive immune response by a cascade of events starting with imiquimod-promoted attraction of immature dendritic antigen-presenting cells (DCs) into the tumor. DCs further mature within the tumor-antigen-rich environment of subsequently cryo-destructed tumor and upon imiquimod-driven migration into the peripheral lymph nodes can stimulate a specific antineoplastic cell-mediated immunity. Finally, continuing imiquimod application after cryosurgery may increase recruitment of activated effector cells into the tumor tissue leading to its destruction. CONCLUSION Cryosurgery during continued topical imiquimod seems to be a promising treatment for lentigo maligna.

Abstract
Congenital malalignment of the great toenails (CMGTN) is a heritable disorder, in which the longitudinal axis of the nail plate is not parallel to the corresponding axis of the distal phalanx of the hallux, but laterally deviated. We describe a pair of 1(1/2)-month-old dizygotic twins with laterally deviated nail plates of the great toenails since birth. By the time the infants were 10 months of age, significant realignment was observed. Adult pedigree members also showed slight similar deviations of the nail plates. We suggest that desynchronization of growth between the nail and the adherent end-phalanx of the hallux may result in temporarily larger nail plates, which are gliding outwards, in order to fit into the underlying bony space. During postnatal life, spontaneous realignment is usually observed, probably as a result of a faster growing end-phalanx.

Abstract
One month after the onset of immunosuppressive treatment with corticosteroids and mycophenolate mofetil for a newly diagnosed pemphigus vulgaris, a 50-year-old female patient developed a new eruption clinically and histomorphologically consistent with eruptive pseudoangiomatosis (EP). Its self-limited course further confirmed this diagnosis. Although initially described as a paediatric eruption, meanwhile more adult cases of EP (30 out of a total of 53 cases identified by a Medline search) are reported in the literature. The review of adult cases of EP disclosed some common clinical and epidemiological characteristics: adult EP cases tend to cluster in the Mediterranean region of Europe, develop during the summer months, sometimes in the form of limited micro-epidemics, affect immunocompromised individuals and have lesions confined to the exposed skin sites. These characteristics, together with the exanthematic nature of the disease in children, point to some vector-transmitted infectious agent as the cause of this probably underdiagnosed disease.

Abstract
Varicella-zoster virus (VZV) is an alpha-herpes virus that causes varicella (chickenpox), establishes latency in dorsal root ganglia and may reactivate to cause herpes zoster (shingles). Postherpetic neuralgia is the most common debilitating complication of herpes zoster. It is currently supposed that scarring of the dorsal root ganglia and atrophy of the dorsal horn as a result of intense inflammation may play a central role in the pathogenesis of this condition. The exact pathogenesis of the inflammatory reaction leading to persistent ganglion damage is still poorly understood. However, immune suppression is a recognized risk factor for the development of postzosteric neuralgia in zoster patients (increased risk, e.g., in aged patients over 80 years or diabetes mellitus patients). There is some evidence that remote streptococcal and staphylococcal infections may induce immunologic disease mechanisms consequently affecting the central nervous system. Since streptococcal and/or staphylococcal superinfection of skin lesions is common in herpes zoster, we present a hypothesis of immunopathogenesis of postzosteric neuralgia, i.e., as the result of augmentation of local ganglion inflammation due to bacteria-driven clonal expansion of VZV-specific T-cell subsets in the affected skin. Based on the aforementioned hypothesis it is interesting: (1) to study the impact of concomitant systemic antibiotic treatment to the standard antiviral regimen on the rate and severity of both bacterial superinfection of zoster skin lesions and postzosteric neuralgia and (2) to quantify the VZV-specific T-cell response as a function of the degree of bacterial superinfection of zoster skin lesions. Challenging of the present hypothesis should provide an effective means of preventing postherpetic neuralgia by preventing and consequently treating the bacterial superinfection of zoster skin lesions.

Abstract
For immunohistochemistry on formalin-fixed, paraffin-embedded specimens adequate pretreatment of the sections to achieve an unmasking of antigenic domains before staining the specimens is necessary. In this study, we compared the effect of microwave and autoclave heating on the expression of the cell proliferation marker Ki-67 (Mib-1) in renal cell carcinomas. A total of 177 formalin-fixed and paraffin-embedded tumor specimens of locally confined renal cell carcinomas with clear cell morphology were investigated. Two different antigen unmasking techniques were used: microwave and autoclave heating. The fraction of Ki-67 positively stained nuclei was determined in APAAP (alkaline phosphatase-antialkaline phosphatase) stained slides. The fraction of Mib-1-labelled cells was significantly higher after autoclave compared to microwave pretreatment (mean value 4.95 vs. 1.43, p<0.001). We recommend the autoclave heating technique for quantitative detection of Ki-67 with the Mib-1 antibody in renal cell carcinomas.

Abstract
Tumour growth curve experiments play an important role in experimental oncology and established methods exist for their unbiased interpretation. However, many authors till introduce systemic biases to their data by using the so-called "relative tumour size" transformation, inspite of wide awarance about the limitations of this latter method. With this communication and by using a fictive exaggeration of the problems connected with the application of this transformation we would like to appeal to both authors and reviewers likewise to ban this potential source of misinterpretation from the oncological literature.
