Abstract
Facial nerve paralysis or Bell's palsy have been suggested as possible consequences of SARS-CoV-2 infections, as well as possible side effects of COVID-19 vaccinations. Google Trends data have been used to evaluate worldwide levels of public awareness for these topics for pre- and post-pandemic years. The results demonstrate a relatively low public interest in facial nerve paralysis in comparison to other more common COVID-19 related topics. Some peaks of interest in Bell's palsy can most likely be explained as triggered by the media. Therefore, Google Trends has shown public's relatively low awareness of this rare neurological phenomenon during the pandemic.

Abstract
BACKGROUND Basal cell carcinomas (BCCs) exhibit aberrant activation of the hedgehog pathway. Sonidegib is a hedgehog pathway inhibitor approved for the treatment of locally advanced BCC (laBCC) and metastatic BCC (mBCC) based on primary results of the BOLT study [Basal Cell Carcinoma Outcomes with LDE225 (sonidegib) Treatment]. OBJECTIVES This is the final 42-month analysis of the BOLT study, evaluating the efficacy and safety of sonidegib. METHODS Adults with no prior hedgehog pathway inhibitor therapy were randomized in a 1 : 2 ratio to sonidegib 200 mg or 800 mg once daily. Treatment continued for up to 42 months or until disease progression, unacceptable toxicity, death, study termination or withdrawal of consent. The primary efficacy end point was the objective response rate (ORR) by central review, assessed at baseline; weeks 5, 9 and 17; then subsequently every 8 or 12 weeks during years 1 or 2, respectively. Safety end points included adverse event monitoring and reporting. RESULTS The study enrolled 230 patients, 79 and 151 in the 200-mg and 800-mg groups, respectively, of whom 8% and 3.3% remained on treatment by the 42-month cutoff, respectively. The ORRs by central review were 56% [95% confidence interval (CI) 43-68] for laBCC and 8% (95% CI 0·2-36) for mBCC in the 200-mg group and 46·1% (95% CI 37·2-55·1) for laBCC and 17% (95% CI 5-39) for mBCC in the 800-mg group. No new safety concerns emerged. CONCLUSIONS Sonidegib demonstrated sustained efficacy and a manageable safety profile. The final BOLT results support sonidegib as a viable treatment option for laBCC and mBCC. What's already known about this topic? Basal cell carcinoma (BCC) is usually treatable with surgery or radiation therapy, but there are limited treatment options for patients with advanced BCC. Sonidegib, a hedgehog pathway inhibitor approved for the treatment of advanced BCC, demonstrated clinically relevant efficacy and manageable safety in prior analyses of the phase II randomized, double-blind BOLT study [Basal Cell Carcinoma Outcomes with LDE225 (sonidegib) Treatment]. What does this study add? This final 42-month analysis of BOLT is the longest follow-up available for a hedgehog pathway inhibitor. Clinically relevant efficacy results were sustained from prior analyses, with objective response rates by central review of the approved 200-mg daily dose of 56% in locally advanced BCC and 8% in metastatic BCC. No new safety concerns were raised. The results confirmed sonidegib as a viable long-term treatment option for patients with advanced BCC.

Abstract
BACKGROUND Patients with locally advanced basal cell carcinoma (laBCC) or metastatic BCC (mBCC), two difficult-to-treat populations, have had limited treatment options. Sonidegib, a hedgehog pathway inhibitor (HPI), was approved in laBCC based on results from the BOLT trial. OBJECTIVE To evaluate long-term efficacy and safety of sonidegib in laBCC and mBCC in the BOLT 18- and 30-month analyses. METHODS BOLT (NCT01327053, ClinicalTrials.gov), a double-blind phase 2 study, enrolled patients from July 2011 until January 2013. Eligible HPI-treatment-naïve patients with laBCC not amenable to curative surgery/radiotherapy or mBCC were randomized 1 : 2 to sonidegib 200 mg (laBCC, n = 66; mBCC, n = 13) or 800 mg (laBCC, n = 128; mBCC, n = 23). Tumour response was assessed per central and investigator review. RESULTS With 30 months of follow-up, among patients treated with sonidegib 200 mg (approved dose), objective response rates were 56.1% (central) and 71.2% (investigator) in laBCC and 7.7% (central) and 23.1% (investigator) in mBCC. Tumour responses were durable as follows: median duration of response was 26.1 months (central) and 15.7 months (investigator) in laBCC and 24.0 months (central) and 18.1 months (investigator) in mBCC. Five patients with laBCC and three with mBCC in the 200-mg arm died. Median overall survival was not reached in either population; 2-year overall survival rates were 93.2% (laBCC) and 69.3% (mBCC). In laBCC, efficacy was similar regardless of aggressive or non-aggressive histology. Sonidegib 200 mg continued to have a better safety profile than 800 mg, with lower rates of grade 3/4 adverse events (43.0% vs. 64.0%) and adverse events leading to discontinuation (30.4% vs. 40.0%). CONCLUSION Sonidegib continued to demonstrate long-term efficacy and safety in these populations. These data support the use of sonidegib 200 mg per local treatment guidelines.

Abstract
BACKGROUND Multiphoton laser tomography (MPT) is a non-invasive technique that allows imaging of skin in vivo with very high spatial resolution and contrast. Previous work of our group has demonstrated that known morphological changes due to erythematogenic ultraviolet B (UVB) irradiation may be imaged in vivo by MPT. The present work investigated if morphological skin changes known from experimental erythematogenic UVB irradiation are also demonstrable in the course of a standard phototherapy regime that implies suberythematogenic doses of narrow band UVB. METHODS Sixteen patients with psoriasis vulgaris receiving a narrow band phototherapy were included. A test field and a light-protected control field were measured with the multiphoton tomograph DermaInspect® at four time points: at baseline, the next day, after 3 days and at the day of the last exposure. RESULTS In the course of the UVB phototherapy, spongiosis and pleomorphy as parameters of inflammation and cellular damage did not show significant changes. By contrast, an adaptive skin reaction with significant changes of keratosis and pigmentation was observed. CONCLUSION MPT is a suitable technique for the investigation of qualitative and quantitative skin changes after UVB irradiation. After suberythematogenic UVB irradiation, photoadaptive skin changes, but no cellular damage can be observed with MPT.

Abstract
BACKGROUND The volume of search engine queries about disease-relevant items reflects public interest and correlates with disease prevalence as proven by the example of flu (influenza). Other influences include media attention or holidays. STUDY GOAL The present work investigates if the seasonality of prevalence or symptom severity of dermatoses correlates with search engine query data. METHODS The relative weekly volume of dermatological relevant search terms was assessed by the online tool Google Trends for the years 2009-2013. For each item, the degree of seasonality was calculated via frequency analysis and a geometric approach. RESULTS Many dermatoses show a marked seasonality, reflected by search engine query volumes. Unexpected seasonal variations of these queries suggest a previously unknown variability of the respective disease prevalence. Furthermore, using the example of allergic rhinitis, a close correlation of search engine query data with actual pollen count can be demonstrated. DISCUSSION In many cases, search engine query data are appropriate to estimate seasonal variability in prevalence of common dermatoses. This finding may be useful for real-time analysis and formation of hypotheses concerning pathogenetic or symptom aggravating mechanisms and may thus contribute to improvement of diagnostics and prevention of skin diseases.

Abstract
BACKGROUND In vivo multiphoton tomography (MPT) of human skin has become a valuable tool for non-invasive examination of morphological and biophysical skin properties and their alterations. So far, skin changes after UVB irradiation were mainly evaluated clinically and histologically. The present study aimed at non-invasive imaging of histological changes during acute UVB irradiation by multiphoton laser tomography. METHODS In 10 volunteers, five areas were irradiated once with an erythematous UVB dose. Multiphoton measurements were performed four times, i.e. before irradiation (baseline), and 24, 48 and 72 h after irradiation, respectively. The data were evaluated for changes of epidermal pleomorphy, spongiosis, pigmentation and thickness. RESULTS The four parameters were altered significantly by acute UVB irradiation, i.e. epidermal pleomorphy, spongiosis, pigmentation and thickness increased within 72 h after irradiation. CONCLUSION Thus, the study has shown that typical epidermal changes induced by acute UVB irradiation can be evaluated by MPT.

Abstract
BACKGROUND Phlebologic diseases have become extremely common and have major socio-economic impact. However, the percentage of dermatologists working in phlebology appears to be decreasing according to the data of the German Society of Phlebology (DGP). METHODS To investigate the reasons for this development, we--on behalf of the DGP--sent a questionnaire to 120 German Departments of Dermatology in autumn 2012. RESULTS In 76 returned questionnaires, the number of physicians with additional fellowship training in phlebology averaged 1.5; the average number of those who fulfill the criteria for training fellows in phlebology was 0.9. In 71.1 % of the departments there was a phlebologist. A special phlebologic outpatient clinic existed in 73.7 % of the departments. Sonography with Doppler (89.5 %) and duplex (86.8 %) was used as the most frequent diagnostic tool. For therapy, compression (94.7 %), sclerotherapy (liquid 78.9 %, foam 63.2 %, catheter 18.4 %), endoluminal thermic procedures (radio wave 28.9 %, laser 17.1 %) and surgery (especially crossectomy and stripping 67.1 %, phlebectomy of tributaries 75 %) were used. The average number of treatments was very heterogenous in the different departments. CONCLUSIONS Phlebology definitely plays an important role in dermatology. Most departments fulfill the formal criteria for the license to conduct advanced training in phlebology. A wide spectrum of phlebological diagnostic and therapeutic procedures is available.

Abstract
Prion diseases are infectious neurodegenerative diseases affecting humans and animals. The food-borne bovine spongiform encephalopathy (BSE) had serious impact on both economy and public health, respectively. To follow the pathogenesis of BSE, oral challenge studies were previously conducted, among others on the Isle of Riems, Germany (Balkema-Buschmann et al., 2011b). In the present work brain and plasma samples from this pathogenesis study were subjected to surface fluorescence distribution analysis (sFIDA). sFIDA is a diagnostic tool that exploits the aggregated state of the disease-related prion protein (PrP) as a biomarker for prion disorders. With the exception of one animal, all tested brain samples from clinical cattle exhibited a high titer of PrP particles. Moreover we could detect PrP aggregates already 16 and 24 months after infection. In contrast to our previous demonstration of PrP particles in blood plasma from scrapie sheep, however, no aggregates could be identified in plasma from pre-clinical and clinical cattle. This is in accordance with other studies suggesting a restriction of the BSE infection to the central nervous system.

Abstract
BACKGROUND/PURPOSE The aim of this study was to demonstrate the effects of selected plant extracts in a cosmetic cream on the dermal network components after a 3-month treatment using an in vivo multiphoton tomographic device. METHODS Twenty-four Caucasian women aged between 45 and 65 applied randomly a cosmetic emulsion B containing active ingredients (soy and jasmine) twice a day on one arm and its vehicle A (without active ingredients) on the other arm during 3 months. Measurements were performed on the internal side of the forearm before starting the treatment (T0), after 4 week (T4) and 12 weeks (T12) treatment. Measurements consisted of a multi-layers acquisitions using a multiphoton tomograph with subcellular resolution. Optical sections (about 6 microm thick) were recorded from 0 to about 200 microm using two different wavelengths: 760 and 820 nm. To compare the series of images and obtain an objective quantification of the signal of second harmonic generation (SHG) and autofluorescence, the method used consisted of taking the integrated brightness of an image (same rectangular area for all images) as a measure of the signal. Following this step, a ratio between brightness of images from the area treated with cream A or B and brightness of untreated area was calculated and used as an assessment of treatment efficacy. The parameter used for statistical analysis (variance analysis) is the difference before and after 12 weeks of treatment by either cream A or B of the signal ratios calculated in the upper dermis (118-130 microm) and those from a deeper region of the upper dermis (165-178 microm). RESULTS Signals (autofluorescence+SHG) of extracellular matrix do not change significantly with time (weeks 0, 4 and 12) when cream A (vehicle with no active ingredient) is applied. Treatment with cream B results in an enhancement in the signal level of extracellular matrix at week 12. The comparison of signals, in both areas (118-130 microm and 160-178 microm), show an higher increase in the deeper region than in the more superficial one for product B while we do not notice any change with product A. CONCLUSION The multiphoton tomograph provided excellent high-resolution images, which describe clearly the different skin layers, single cells and extracellular matrix components in all the 24 volunteers. Statistic analyses reveal a real effect for product B with selected plant extracts, known to increase collagen synthesis. Changes observed are characteristics of modifications in dermal collagen and elastin content. To our knowledge, it is the first time that it was possible to demonstrate in vivo the effect of a cosmetic product on the superficial dermal layer, in a non-invasive and non-destructive process, i.e. without cutting the skin.

Abstract
Over the last decades, there has been a dramatic increase of skin tumour incidence that results from actinic damage. This increase is mainly due to the current demographic development, but also due to a change in spare time habits. Thus, the treatment and prevention of light induced skin tumours is gaining interest, but also the treatment of photoaged skin. This review will focus on 1) the basic principles of actinic damage including carcinogenesis; 2) treatment options for photoaged skin and 3) an overview of current therapy concepts of light induced skin tumours.

Abstract
Benign symmetric lipomatosis, also known as Madelung's disease or Launois-Bensaude syndrome, is a rare disease, the etiology of which is still unknown. The presence of multiple, symmetric, nonencapsulated lipomatous masses in the face, neck, upper arms and upper trunk is typical. Until now many causes have been discussed among which liver dysfunctions are described frequently. In up to 90% of patients, alcoholism is observed. In our case the Launois-Bensaude syndrome developed after liver transplantation in a 49-year-old female patient suffering from decompensated cirrhosis (Child-Pugh C score: 12 points). Shortly after the transplantation a slow progress in tissue-building appeared on both upper arms, cervical areas as well as in the face. During postsurgical prednisolone therapy, a massive increase in fluid in the tissue developed, which led to a discontinuation of this therapy regimen. In the further course there was an increase in weight of 20 kg. As far as we know, this case is the first description of the induction of a Launois-Bensaude syndrome following liver transplantation.

Abstract
BACKGROUND Probiotic bacteria are proposed to alleviate atopic dermatitis (AD) in infants. There are few indications about the effect of probiotics on AD in adults. OBJECTIVE The purpose of this study was to elucidate the influence of a probiotic drink containing a combination of the probiotics Lactobacillus paracasei Lpc-37, Lactobacillus acidophilus 74-2 and Bifidobacterium animalis subsp. lactis DGCC 420 (B. lactis 420) in healthy volunteers and in patients with AD on clinical and immunological parameters and their detection in feces. METHODS A double-blind, placebo-controlled, randomized cross-over study was conducted in 15 healthy adults and 15 patients with AD. The probiotic product or placebo was given over 8 weeks. A 2-week washout period was interconnected before the intervention was crossed. At the end of each period, blood and stool samples were collected. In patients, the severity of AD was evaluated using the Scoring of Atopic Dermatitis (SCORAD). RESULTS L. paracasei and B. lactis were recovered in high numbers in feces after supplementation, whereas L. acidophilus marginally increased. In patients, the SCORAD tended to decrease by 15.5% (P=0.081). Major lymphocyte subsets were not affected by the probiotic intervention. However, CD57(+) increased significantly (P=0.034) in healthy subjects after probiotic intake and was not changed in patients, whereas CD4(+)CD54(+) decreased significantly (P=0.031) in patients with AD and remained uninfluenced in healthy subjects. The expression of CD4(+)CD25(+) T cells was similar in healthy subjects and AD patients. The phagocytic activity of monocytes and granulocytes was significantly increased in healthy subjects after probiotic intervention (P=0.014). CONCLUSION L. paracasei Lpc-37 and B. lactis 420 are able to colonize the intestine transiently. This study reveals that the probiotics differently modulate peripheral immune parameters in healthy subjects and patients with AD.

Abstract
8567 Background: To date, there is no evidence of survival benefit from randomized trials in stage IV metastatic melanoma (MM) after disease progression to first-line therapy. Therefore, we initiated a phase III trial to evaluate the impact on survival of polychemotherapy in patients (pts.) receiving best supportive care (BSC) as second-line therapy. Methods: This prospective multicenter controlled study was conducted by the Dermatologic Cooperative Oncology Group (DeCOG) with 13 participating centers. Pts. with stage IV MM disease between 18 and 75 yrs. and a Karnofsky performance status (KPS) > 60 with progression after first-line chemotherapy or chemo-immunotherapy were offered to choose between polychemotherapy + BSC or BSC alone. Pts. were required to have adequate renal, liver and bone marrow function. The regimen consisted of cisplatin (50 mg/m2), vindesine (3 mg/m2) and dacarbacin (450 mg/m2) given on day 1 and 8 every 28 days (CVD). Reevaluation according to WHO response criteria were performed every 2 cycles. Primary endpoint was the median overall survival (OS). Secondary endpoints were overall response rate (OR) (only CVD arm) and quality of life (QOL). Results: Between 1/02 and 8/06 120 pts. were recruited, a minority of 35 pts. (29%) chose the BSC arm (A) and 85 (71%) the CVD + BSC arm (B). Five pts. were ineligible, and thus 115 pts. treated per protocol. There was a significant lower KPS in arm A at study entry. At the time of data analysis, 85% of the pts. had died from melanoma. There was no siginificant difference (p=0.093) in median OS between the two arms, 9.0 [95% CI: 3,9–14,1] months in arm A and 8.0 [95% CI: 6,5–9,5] months in arm B. The OR in arm B was 7.5% (2 CR, 3 PR). Conclusions: Polychemotherapy (CVD) + BSC as second-line therapy in stage IV MM does not improve overall survival as compared to BSC alone. No significant financial relationships to disclose.

Abstract
Two-photon medical imaging has found its way into dermatology as an excellent method for noninvasive skin cancer detection without need of contrast agents as well as for in situ drug screening of topically-applied cosmetical and pharmaceutical components. There is an increasing demand to apply the multiphoton technology also for deep-tissue skin imaging as well as for intracorporal imaging. We report on the first clinical use of multiphoton endoscopes, in particular of a miniaturized rigid two-photon GRIN lens endoscope. The microendoscope was attached to the multiphoton tomograph DermaInspect and employed to detect the extracellular matrix proteins collagen and elastin in the human dermis of volunteers and patients with ulcera by in vivo second harmonic generation and in vivo two-photon autofluorescence.

Abstract
The intercellular adhesion molecule-1/CD54 (ICAM-1) functions as a counterreceptor for other adhesion molecules (e.g. the lymphocyte function-associated antigen-1/CD11a/CD18) required for the interaction of a large variety of cells with leucocytes. Constitutive expression of ICAM-1 in human epidermoid cells (KB cells) is low, but inducible by interferon-gamma (IFN-gamma). Treatment of KB cells with microtubule-disrupting agents, like colchicine, nocodazole and vinblastine, potentiated the constitutive and cytokine-induced ICAM-1 expression on the cell surface. Actinomycin D inhibited microtubule-disrupting agent-induced ICAM-1 surface expression. Increased steady-state levels of ICAM-1 transcripts were found after treatment of KB cells with microtubule-disrupting agents. However, microtubule-disrupting agents neither altered the glyceraldehyde-3-phosphate dehydrogenase mRNA levels nor the amount of expressed alpha(2)-, alpha(3)-and beta(1)-integrins at the cell surface. In addition, they did not change the ICAM-1 mRNA half-life. These studies indicate a control function of the microtubule network on the expression of ICAM-1.

Abstract
Adult cutaneous Langerhans cell histiocytosis (LCH) is a rare disease. We report two cases illustrating the variability of the clinical presentation and the response to treatment. In both cases a remission was achieved: in one case a partial remission with psoralen plus UVA irradiation (PUVA) and methotrexate plus topical corticosteroid ointment; in the other case by treatment with thalidomide. Despite a therapeutic response, both patients later developed haematological malignancies: a chronic myelo-monocytic leukaemia and an acute lymphatic leukaemia. In conclusion, patients with adult cutaneous LCH should be monitored carefully so that a secondary malignancy is not overlooked.

Biogenic amines are potential irritants e.g. in fish-, meat-, milk- and egg-processing professions like cooks, butchers and bakers. The aim of this study was to test the irritative and barrier-disrupting properties of the biogenic amines ammonium hydroxide (AM), dimethylamine (DMA) and trimethylamine (TMA). A repeated sequential irritation of 30 min twice per day was performed over a total of 4 days (tandem repeated irritation test) on the back of 20 healthy volunteers of both sexes with AM, DMA, TMA and sodium lauryl sulphate (SLS). The epidermal barrier function was assessed with a Tewameter TM 210, stratum corneum surface pH was measured with a Skin-pH-Meter 900, inflammation was assessed with a Chromameter CR-300 on the a* axis for redness and a visual score was recorded. All tested biogenic amines (AM, DMA and TMA) induced a barrier disruption and a pH increase paralleled with a 1-day-delayed onset of inflammatory signs. These effects were further enhanced and accelerated by a sequential application of SLS together with the biogenic amines, and inflammation occurred earlier than with the single compounds. Acetic acid (AA) in contrast did only show mild barrier disruption and no significant inflammatory signs. Our system allowed a ranking of the different compounds in their irritative potential in the tandem irritation with SLS: SLS > NaOH > TMA > AA > AM > DMA. The results are suggestive that in the food-processing industry the simultaneous contact with biogenic amines and harmful detergents like SLS should be minimized.

Abstract
Irritant and allergic contact dermatitis are commonly seen in patients complaining about itching, burning and irritation in the vulvar area. Irritation often precedes allergic sensitization. Clinically, irritant and allergic contact dermatitis can be difficult to distinguish. Diagnosis is made by history, clinical investigation and patch testing. Recommended patch test series are the standard series, a medicament series, the patient's own topical medicaments, popular remedies and other suspected products. A skin biopsy may be useful to establish the diagnosis of contact dermatitis, but it is usually not helpful for the differential diagnosis between irritant and allergic dermatitis.

Abstract
BACKGROUND Stage IV melanoma has a poor prognosis with a median survival of 3-11 months from diagnosis of distant metastases. Response rates in first-line regimens range around 15-20%. Non-responders have a median survival around 6 months. Currently, no second-line treatment in advanced melanoma has been established. PATIENTS AND METHODS In a clinical phase II study we evaluated the efficacy of liposomal doxorubicin (Caelyx) in 30 patients (17 m, 13 f) with progressing metastatic melanoma who had failed a previous chemotherapy. Liposomal doxorubicin was given in an outpatient setting at a dose of 50 mg/m2 i.v. on d1, d22, d43 and d64, subsequently at 40 mg/m2 at d85 before first staging and in 4-week intervals thereafter. Treatment was very well tolerated with 100 cycles given in total. Response rate, survival time, time-to-progression and toxicity were assessed. RESULTS Erythrodysesthesia was the most severe toxicity in 6% at CTC grade 3. Liposomal doxorubicin was of limited clinical efficacy with 21 patients progressing within the first 12 weeks. However, 7 patients were treated 3-9 months and were stable for >90 days, achieving 5 SD, 1 PR and 1 CR. Median survival after initiation of second-line treatment was 214 days (95% CI: 151-304 days) with 7 patients surviving >300 and 5 patients >400 days. CONCLUSIONS Liposomal doxorubin as monotherapy is well tolerated but of limited clinical efficacy. Whether the survival benefit of a significant proportion of patients (20%) holds true in larger cohorts and whether the efficacy of liposomal doxorubicin can be improved by combinations without compromising the low toxicity profile needs further studies.

Abstract
Langerhans cell histiocytosis (LCH) represents a group of rare histiocytic syndromes characterized by tissue infiltration with dendritic cells. The management of LCH is difficult as these disorders respond inconsistently to immunosuppressive and chemotherapeutic strategies. Thalidomide (N-phtalimidoglutarimide), initially used as a tranquilizer, has recently been used in the management of several inflammatory skin diseases. We describe the case of a 38-year-old male with mucocutaneous LCH. A treatment course with 6 cycles of 2-chlorodeoxyadenosin (cladribine) was initiated. This was well tolerated but withdrawn after 6 months to prevent secondary malignancy. A partial remission was seen. Subsequently, a treatment course with thalidomide 200 mg daily was started. This therapy resulted in a significant improvement of the mucocutaneous lesions within 4 weeks and complete healing was achieved after 3 months. Treatment was then successfully continued with daily doses of 100 mg to prevent relapse. In conclusion, thalidomide monotherapy represents an effective, safe and well-tolerated treatment option that should be considered as first-line therapy for mucocutaneous LCH.

Abstract
Erythema induratum of Bazin (EIB) is considered a tuberculide reaction and consists of recurrent painful nodules predominantly on the calves. Clinically it has common features with diseases like nodular vasculitis, perniosis, polyarteritis nodosa and erythema nodosum. Poncet's disease is a reactive arthritis that may accompany tuberculosis. We report a case of a young woman in which the simultaneous occurrence of erythema induratum of Bazin and Poncet's disease led to a clinical picture very similar to Löfgren's syndrome. The final diagnosis was obtained by polymerase chain reaction detection of mycobacterial DNA in a skin biopsy. A systemic therapy with tuberculostatic drugs led to the disappearance of symptoms. The presented case shows the usefulness of polymerase chain reaction diagnostics in EIB patients without other clinical signs of tuberculosis and a confusing combination of symptoms, and further confirms the presence of mycobacterial DNA in EIB lesions.

Abstract
Subungual chondroma is a rare occurrence of periosteal chondroma, which mainly affects short tubular bones of the hands and feet. Transformation towards malignancy has been described in a small number of cases; however histologic diagnosis can prove to be difficult, especially with regard to well differentiated chondrosarcoma. We report the case of a 14 year old girl with a one year history of subungual chondroma of the fourth toe with good clinical response to surgical removal.

Abstract
PURPOSE Matrix metalloproteinases (MMPs) are a family of structurally related zinc-dependent endopeptidases that are able to degrade extracellular matrix components. MMPs play a role in tumor invasion and tumor metastasis. MMP-2 (also known as gelatinase A) is expressed in human melanoma cells. METHODS In this study, we measured MMP-2 in 337 serum probes of 166 melanoma patients with a recently developed enzyme immunoassay and compared these data with the tumor stage, presence of metastases, and the levels of S100beta and soluble intracellular adhesion molecule-1 (sICAM-1) in serum. RESULTS The mean levels were (189.2 +/- 50.8) ng/ml for MMP-2, (263.2 +/- 74.1) ng/ml for sICAM-1, and (0.424 +/- 1.568) U/ml for S100beta. There was a statistical significant correlation of MMP-2 with sICAM-1 (P=0.05) and Sl00beta (P=0.01). The mean MMP-2 levels (in ng/ml) in patients with metastatic melanoma were 196.4 +/- 54.0 versus 182.6 +/- 46.9 in non-metastasizing melanoma (P=0.037). However, there was no significant difference in MMP-2 levels between the different tumor stages. CONCLUSION Determination of MMP-2 serum levels is of limited value as a tumor marker in melanoma, though there are higher levels in the more advanced disease.

Abstract
HISTORY AND CLINICAL FINDINGS The case of a 70 year old male is presented. Past medical history revealed the following diagnoses: liver cirrhosis, splenomegaly, thrombocytopenia, macrocytic anaemia, chronic obstructive pulmonary disease, type IIa diabetes mellitus and peripheral vascular disease of the lower limbs with chronic leg ulcers. Within 6 weeks the patient developed an increasing number of pigmented lanugo type hair over both cheeks, zygomatic arches and temples. The diagnosis of circumscribed acquired hypertrichosis lanuginosa (AHL) was established. Bone marrow biopsy revealed presence of acute myeloid leukemia. THERAPY AND CLINICAL COURSE Chemotherapy with hydroxycarbamide (Syrea) was started without effect on haematologic parameters. The patient was transferred to the oncology unit where he died soon afterwards. CONCLUSION Acquired hypertrichosis lanuginosa (AHL) is a paraneoplastic syndrome. It is mainly associated with adenocarcinoma of lung and bowel, however other histologic types of tumours and localisations have been described. About 50 cases have been reported in the literature until 1998. To our knowledge this is the first case of AHL described in association with acute myeloid leukemia.
