Objective: To describe and analyze the clinical, histological and potential etiopathological aspects of KP. Methods: The dermatoscopic features of a new case of KP of childhood are investigated. The presence of human papillomavirus (HPV) DNA in lesional skin was studied by polymerase chain reaction. Furthermore, all cases of KP of childhood reported so far were reviewed. Results: As a diagnostic tool, we describe for the first time a dermatoscopic feature, namely a cribriform pattern of KP, in an 11-year-old boy. In addition, we detected HPV (type 57) in his KP lesions. Conclusions: Dermatoscopic examination might be a useful tool to distinguish KP from other skin lesions, e.g. common warts. The detection of HPV type 57 might hint to an etiological role of HPV for KP.}, language = {en} } @article{BenoitGoebeler2015, author = {Benoit, Sandrine and Goebeler, Matthias}, title = {Mepacrine in recalcitrant cutaneous lupus erythematosus: old-fashioned or still useful?}, series = {Acta Dermato-Venereologica}, volume = {95}, journal = {Acta Dermato-Venereologica}, doi = {10.2340/00015555-2031}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-149181}, pages = {596-599}, year = {2015}, abstract = {Treatment of recalcitrant cutaneous lupus erythematosus (CLE) is challenging. In situations where conventional treatment approaches fail mepacrine - an antimalarial/antiinfiammatory drug that has fallen into oblivion in the last decades might still be a promising option. We retrospectively analysed medical records of 10 patients with refractory CLE that were treated with mepacrine (100-200 mg/day) as mono- or combination therapy for various time intervals between 2001 and 2013 at the University Hospital Wurzburg. Mepacrine was generally well tolerated. Side effects were mild and usually resolved after reduction or cessation. Over 50\% of the patients experienced amelioration of their symptoms despite a previously recalcitrant clinical course. Altogether, our data demonstrate that mepacrine still remains a useful and effective therapeutic option for otherwise treatment-resistant CLE.}, language = {en} } @article{KolbMaeurerGoebelerMaeurer2015, author = {Kolb-M{\"a}urer, Annette and Goebeler, Matthias and M{\"a}urer, Mathias}, title = {Cutaneous adverse events associated with interferon-\(\beta\) treatment of multiple sclerosis}, series = {International Journal of Molecular Sciences}, volume = {16}, journal = {International Journal of Molecular Sciences}, doi = {10.3390/ijms160714951}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-148451}, pages = {14951-14960}, year = {2015}, abstract = {Interferons are widely used platform therapies as disease-modifying treatment of patients with multiple sclerosis. Although interferons are usually safe and well tolerated, they frequently cause dermatological side effects. Here, we present a multiple sclerosis (MS) patient treated with interferon-\(\beta\) who developed new-onset psoriasis. Both her MS as well as her psoriasis finally responded to treatment with fumarates. This case illustrates that interferons not only cause local but also systemic adverse events of the skin. These systemic side effects might indicate that the Th17/IL-17 axis plays a prominent role in the immunopathogenesis of this individual case and that the autoimmune process might be deteriorated by further administration of interferons. In conclusion, we think that neurologists should be aware of systemic cutaneous side effects and have a closer look on interferon-associated skin lesions. Detection of psoriasiform lesions might indicate that interferons are probably not beneficial in the individual situation. We suggest that skin lesions may serve as biomarkers to allocate MS patients to adequate disease-modifying drugs.}, language = {en} } @article{VamanVSPoppeHoubenetal.2015, author = {Vaman V.

Its expression is increased in many malignant tumors. However, little is known about the physiological role of the protein. In the present study, we investigated the expression and function of LASP1 in normal skin, melanocytic nevi and malignant melanoma. In normal skin, a distinct LASP1 expression is visible only in the basal epidermal layer while in nevi LASP1 protein is detected in all melanocytes. Melanoma exhibit no increase in LASP1 mRNA compared to normal skin. In melanocytes, the protein is bound to dynamin and mainly localized at late melanosomes along the edges and at the tips of the cell. Knockdown of LASP1 results in increased melanin concentration in the cells. Collectively, we identified LASP1 as a hitherto unknown protein in melanocytes and as novel partner of dynamin in the physiological process of membrane constriction and melanosome vesicle release.}, language = {en} }
