  abstract  = {Background: Bowen's disease (BD) of the nail unit is associated with human papillomavirus (HPV) infection. Objective: This study aimed to investigate the frequency of high-risk HPV infection, gender, age and digital distribution in this condition. Methods: Biopsy specimens of 3 consecutive cases with periungual BD were investigated for the presence of HPV DNA by in situ hybridization and by polymerase chain reaction (PCR). Furthermore, 74 cases of ungual BD conducted with HPV genotyping as reported in the literature were reviewed. Results: PCR of biopsy specimens revealed in 2 cases infection with HPV-16 and in 1 case with HPV-73. Additionally, in 1 HPV-16-positive case HPV-31/33 was detected by in situ hybridization. In line, review of the literature demonstrated a clear association of HPV-positive BD with high-risk HPV types. Interestingly, age at diagnosis was significantly lower in women. Whereas in both genders the second to fourth fingers on both hands were commonly diseased, only in men the thumbs were also prominently affected. Conclusions: Infection with high-risk HPV types is common in BD of the nail unit suggesting the aetiological cause. Therefore, patients and partners should be closely followed up for digital and genital HPV-associated lesions.},

  abstract  = {Mycosis fungoides (MF) is the most common cutaneous T-cell lymphoma (CTCL) (1). Most patients initially respond well to standard therapy, but advanced MF is often treatment refractory. Thus, a combination of the available treatment options is an important strategy. Total skin electron beam radiation (TSEB) is effective in MF, with a complete remission rate of up to 90\% in the early stages. However, in patients with more advanced stages, remission rates are considerably lower (2, 3). Denileukin diftitox (DD) (Ontak®) is a recombinant fusion protein of the receptor-binding domain of interleukin (IL)-2 and the enzymatic and translocation domains of diphtheria toxin (4). It targets the alpha-subunit of the IL-2-receptor (CD25). There are no reports on this combination therapy in MF.},

  abstract  = {OBJECTIVE: To demonstrate the role of angiogenesis in the progression of cutaneous squamous cell carcinoma. INTRODUCTION: Angiogenesis is a pivotal phenomenon in carcinogenesis. Its time course in cutaneous squamous cell carcinoma has not yet been fully established. METHODS: We studied the vascular bed in 29 solar keratoses, 30 superficially invasive squamous cell carcinomas and 30 invasive squamous cell carcinomas. The Chalkley method was used to quantify the microvascular area by comparing panendothelial (CD34) with neoangiogenesis (CD105) immunohistochemical markers. The vascular bed from non-neoplastic adjacent skin was evaluated in 8 solar keratoses, 10 superficially invasive squamous cell carcinomas and 10 invasive squamous cell carcinomas. RESULTS: The microvascular area in CD105-stained specimens significantly increased in parallel with cutaneous squamous cell carcinoma progression. However, no differences between groups were found in CD34 sections. Solar keratosis, superficially invasive squamous cell carcinoma and invasive squamous cell carcinoma samples showed significant increases in microvascular area for both CD34- and CD105-stained specimens compared with the respective adjacent skin. DISCUSSION: The angiogenic switch occurs early in the development of cutaneous squamous cell carcinoma, and the rate of neovascularization is parallel to tumor progression. In contrast to panendothelial markers, CD105 use allows a dynamic evaluation of tumor angiogenesis. CONCLUSION: This study demonstrated the dependence of skin carcinogenesis on angiogenesis.},

It has long been known in Asian medicine for its anticarcinogenic, antihypertensive and serum cholesterol level reduction properties. Nevertheless, the consumption of raw or not well-cooked mushrooms may cause skin eruptions which usually occur 24 to 48 hours after ingestion and are characterized by linearly arranged pruritic erythematous papules and plaques. We present a 36-year-old patient that developed typical symptoms 24 hours after consumption of shiitake mushrooms and summarize therapeutic options and particularities of this disease.},

  abstract  = {Background Merkel cell carcinoma (MCC) is a rare cutaneous neoplasm with increasing incidence, aggressive behavior and poor prognosis. Somatostatin receptors (SSTR) are expressed in MCC and represent a potential target for both imaging and treatment. Methods To non-invasively assess SSTR expression in MCC using PET and the radiotracers [68Ga]DOTA-D-Phe1-Tyr3-octreotide (DOTATOC) or -octreotate (DOTATATE) as surrogate for tumor burden. In 24 patients with histologically proven MCC SSTR-PET was performed and compared to results of computed tomography (CT). Results SSTR-PET detected primary and metastatic MCC lesions. On a patient-based analysis, sensitivity of SSTR-PET was 73\% for nodal metastases, 100\% for bone, and 67\% for soft-tissue metastases, respectively. Notably, brain metastases were initially detected by SSTR-PET in 2 patients, whereas liver and lung metastases were diagnosed exclusively by CT. SSTR-PET showed concordance to CT results in 20 out of 24 patients. Four patients (17\%) were up-staged due to SSTR-PET and patient management was changed in 3 patients (13\%). Conclusion SSTR-PET showed high sensitivity for imaging bone, soft tissue and brain metastases, and particularly in combination with CT had a significant impact on clinical stage and patient management.},

  abstract  = {A proangiogenic micromilieu is associated with a worse prognosis in systemic lymphoma. Hence, targeting the tumour microenvironment and its vasculature has evolved as a promising novel treatment strategy. The role of tumour neoangiogenesis in cutaneous B-cell lymphoma, however, has not yet been elucidated. Therefore, we examined the expression of vascular endothelial growth factor (VEGF) and its receptors VEGFR-1 and VEGFR-2, as well as microvessel density by immunohistochemistry in paraffin-embedded specimens of different subtypes of primary cutaneous B-cell lymphomas, systemic diffuse large B-cell lymphoma, and cutaneous B-cell pseudolymphoma. Primary cutaneous large B-cell lymphoma (PCLBCL) were characterized by significantly higher intratumoral expression levels of VEGF and its receptors in comparison with the indolent lymphoma subtypes. Moreover, PCLBCL exhibited significantly higher intratumoral microvessel counts. Our study provides evidence that the most aggressive subtype of cutaneous B-cell lymphoma, PCLBCL, is characterized by a proangiogenic micromilieu.},
