Abstract
Psoriasis and hidradenitis suppurativa are often associated with obesity. Because chronic low-grade inflammation underlies these 2 diseases, they can progress to more severe forms in patients with obesity if weight-reduction measures are not taken. This review covers pharmacologic alternatives for treating obesity, with emphasis on the benefits associated with the novel use of glucagon-like peptide-1 (GLP-1) agonists that act on satiety receptors. These drugs have led to greater weight loss in clinical trials and real-world settings than orlistat, which until recently was the only drug approved for treating obesity in the European Union. Although experience with GLP-1 agonists in patients with obesity and inflammatory skin diseases is currently scarce, the promising results reported suggest they may offer a useful tool for managing obesity.

Abstract
BACKGROUND Reliable prognostic factors for patients with primary cutaneous anaplastic large cell lymphoma (PCALCL) are lacking. OBJECTIVE To identify prognostic factors for specific survival in patients with PCALCL. METHODS Using the convenience sampling method, patients with PCALCL diagnosed from May 1986 to August 2017 in 16 University Departments were retrospectively reviewed. RESULTS One hundred eight patients were included (57 males). Median age at diagnosis was 58 years. All of them showed T1-3N0M0 stages. Seventy per cent of the cases presented with a solitary lesion, mostly at the limbs. Complete response rate after first-line treatment was 87%, and no advantage was observed for any of them (surgery, radiotherapy, chemotherapy or other approaches). Nodal and visceral progression rate was 11% and 2%, respectively. 5-year specific survival (SSV) reached 93%; 97% for T1 patients and 84% for T2/T3 patients (P = 0.031). Five-year SSV for patients developing early cutaneous relapse was 64%; for those with late or no relapse, 96% (P = 0.001). Estimated median SSV for patients showing nodal progression was 103 months (95% CI: 51-155 months); for patients without nodal progression, estimated SSV did not reach the median (P < 0.001). Nodal progression was an independent predictive parameter for shorter survival (P = 0.011). CONCLUSION Multiple cutaneous lesions at presentation, early skin relapse and nodal progression portrait worse prognosis in patients with PCALCL.

Abstract
BACKGROUND Ixekizumab (anti-IL17A) is effective as treatment for moderate-to-severe plaque psoriasis, but real-life data on effectiveness and safety are currently very limited. OBJECTIVE To evaluate the efficacy and safety of ixekizumab in a cohort of real-life plaque psoriasis patients. METHODS Retrospective chart review of 100 patients with moderate-to-severe plaque psoriasis treated with ixekizumab at seven Spanish dermatological centres. RESULTS According to the as observed analysis, the percentage of patients achieving a 75% and 90% of reduction from the baseline score of Psoriasis Area and Severity Index (PASI) was 87.5%-50.0% at week 12-16; 88.3%-58.4% at week 24 and 82.9%-58.5% at week 52, respectively. The mean ± standard deviation (SD) score of PASI at baseline was 12.9 ± 9.2, and it declined rapidly after ixekizumab administration to 1.9 ± 4.0 (P < 0.001) at week 12-16 and was maintained at 1.7 ± 4.1 and 1.8 ± 2.9 at week 24 and 52, respectively. Ixekizumab response was not affected by clinical variables like body mass index, disease duration or the presence of psoriatic arthritis. However, the bio-naive group showed significantly higher PASI 75 response rate at week 12-16 compared to patients previously exposed to biologic agents (P = 0.037). Twenty-six (26%) patients experienced adverse events (AEs) during the follow-up period, being most of them of mild-to-moderate intensity. The most common AE was local reaction at the site of injection (14/26; 53.8%). At the end of the observational period, 15 (15%) patients discontinued ixekizumab treatment due to limited clinical improvement (n = 11), adverse events (n = 3) or lost to follow-up (n = 1) within a mean ± SD time of 6.0 ± 3.9 months. CONCLUSION The present study illustrates the initial experience with ixekizumab in real-world clinical practice confirming its usefulness and safety in the management of plaque psoriasis patients.

Abstract
The dissipation of atrazine, chlorpyrifos and iprodione in a biopurification system and changes in the microbial and some biological parameters influenced by the rhizosphere of Lolium perenne were studied in a column system packed with an organic biomixture. Three column depths were analyzed for residual pesticides, peroxidase, fluorescein diacetate activity and microbial communities. Fungal colonization was analyzed by confocal laser scanning microscopy to assess the extent of its proliferation in wheat straw. The L. perenne rhizosphere enhanced pesticide dissipation and negligible pesticide residues were detected at 20-30 cm column depth. Atrazine, chlorpyrifos and iprodione removal was 82, 89 and 74% respectively in the first 10 cm depth for columns with vegetal cover. The presence of L. perenne in contaminated columns stimulated peroxidase activity in all three column depth sections. Fluorescein diacetate activity decreased over time in all column sections with the highest values in biomixtures with vegetal cover. Microbial communities, analyzed by PCR-DGGE, were not affected by the pesticide mixture application, presenting high values of similarity (>65%) with and without vegetal cover. Microbial abundance of Actinobacteria varied according to treatment and no clear link was observed. However, bacterial abundance increased over time and was similar with and without vegetal cover. On the other hand, fungal abundance decreased in all sections of columns after 40 days, but an increase was observed in response to pesticide application. Fungal colonization and straw degradation during pesticide dissipation were verified by monitoring the lignin autofluorescence loss.

Abstract
BACKGROUND Nonsurgical treatment (radiotherapy, imiquimod) is increasingly employed for the management of lentigo maligna (LM). While the diagnosis of LM remains difficult, the detection of treatment failure is even more challenging. OBJECTIVES To describe the sensitivity and specificity for the diagnosis of LM of individual features and methods using dermoscopy and in vivo reflectance confocal microscopy (RCM) to aid in the detection of treatment failure of LM following nonsurgical treatment. METHODS A retrospective study of dermoscopy and RCM images (blinded to the correlation with pathology) in patients with biopsy-confirmed LM who were undergoing nonsurgical treatment in two referral institutions - one in Sydney, Australia, and the other in Barcelona, Spain. Ninety-eight patients were treated nonsurgically for LM during the period 2006-2012. Thirty-one patients had abnormal dermoscopy or RCM evaluation, and had a biopsy that identified LM recurrence in 15 patients and nonmelanoma diagnoses in 16 patients (one Bowen disease, 15 solar changes). RESULTS The diagnosis of treatment failure was difficult with dermoscopy, with a sensitivity of 80% and specificity of 56%, even with the interpretation of an expert. The best criterion was asymmetric hyperpigmented follicular openings, but this was present in only 47% of treatment failure LM. Isolated, very fine brown dots ('dust' appearance) correlated highly with the diagnosis of treatment failure LM (73% sensitivity and 88% specificity) and with pagetoid cells seen with RCM. The LM score, comprising six criteria, had a specificity of 94% and sensitivity of 100%. CONCLUSIONS These methods and descriptors should help to manage the diagnosis of treatment failure.

Abstract
BACKGROUND Intravenous rituximab is a safe and effective option for the treatment of systemic non-Hodgkin B-cell lymphoma. The effectiveness of intralesional rituximab (ILR) in primary cutaneous B-cell lymphomas (PCBL) has been described in a small number of patients. OBJECTIVES To evaluate the effectiveness, tolerance and adverse effects of ILR in patients with follicle centre (FCL) and marginal zone (MZL) PCBL. METHODS This was an epidemiological observational multicentre study of patients with PCBL treated with ILR. RESULTS Seventeen patients with MZL and 18 with FCL PCBL were included. The median number of lesions treated was two per patient. The treatment regimen used in 74% of the patients was a course of three injections in a single week at 1-month intervals. The dose per lesion and day of treatment was 10 mg in 71% of the patients. The median cumulative dose of rituximab per lesion was 60 mg (range 13-270) and per patient was 150 mg (range 20-360 mg). Complete response (CR) and partial response were achieved in 71% and 23% of patients, respectively. The median time to CR in patients who received 10 mg of ILR per lesion was 8 weeks. Similar response rates were observed in MZL and FCL. Median disease-free survival was 114·1 weeks. No parameters that significantly predicted CR were identified. Adverse reactions were recorded in 19 patients; the most frequent was localized pain at the injection site. Median follow-up was 21 months. CONCLUSIONS Intralesional rituximab is a well-tolerated and effective treatment for FCL and MZL PCBL. It should be considered a useful alternative in patients with recurrent lesions and in which the sequelae of radiotherapy or surgery would be significant.

Abstract
The effect of pulp mill sludge addition (10-30 Mg/ha) to soil derived from volcanic ash (Andisol) on soil characteristics, microbial community and Lolium perenne L. cv quartet. biomass production was evaluated in field assays. Soil without sludge was used as a control treatment. The sludge addition improved the chemical properties of the soil. Organic matter and phosphorous content increased in the soil with increasing amounts of sludge, obtaining 35% more organic matter content with the application of 30 Mg/ha than the control soil. The phosphorous was accumulated into the soil after the end of cultivation improving the phosphorous pool in the soil. When 30 Mg/ha sludge was added to the soil, a biomass of Lolium perenne, was 60% more than the control soil at the end of the experiment. The analysis of soil microbial community showed that the application of sludge did not modify greatly the microbial community of fungi and bacteria even when high doses were applied.

Abstract
The white-rot fungus Anthracophyllum discolor immobilized on wheat grains was evaluated for chlorophenol (2,4-dichlorophenol, 2,4,6-trichlorophenol and pentachlorophenol) degradation in allophanic soil columns activated by acidification. Columns without inoculation were used as the control to evaluate the adsorption capacity of the soil columns. The chlorophenols were removed efficiently in soil columns by both adsorption and degradation processes. In inoculated soil columns, 2,4-dichlorophenol was highly degraded and this degradation is associated with a high production of manganese peroxidase. 2,4,6-trichlorophenol was degraded to a lesser extent compared with 2,4-dichlorophenol. Pentachlorophenol was first removed by adsorption and then through degradation by the fungus. Manganese peroxidase activity was lowest when the column was fed with pentachlorophenol and highest when the column was fed with 2,4-dichlorophenol. Laccase was also produced by the fungus but to a lesser degree.

Abstract
The consensus statement on the management of primary cutaneous melanoma that we present here was based on selection, discussion, review, and comparison of recent literature (including national and international guidelines). The protocols for the diagnosis, treatment, and follow-up used in the hospital centers throughout Catalonia and the Balearic Isles belonging to the Network of Catalan and Balearic Melanoma Centers were also considered. The main objective of this statement was to present the overall management of melanoma patients typically used in our region at the present time. As such, the statement was not designed to be an obligatory protocol for health professionals caring for this group of patients, and neither can it nor should it be used for this purpose. Professionals reading the statement should not therefore consider it binding on their practice, and in no case can this text be used to guarantee or seek responsibility for a given medical opinion. The group of dermatologists who have signed this statement was created 3 years ago with the aim of making our authorities aware of the importance of this complex tumor, which, in comparison with other types of cancer, we believe does not receive sufficient attention in Spain. In addition, the regular meetings of the group have produced interesting proposals for collaboration in various epidemiological, clinical, and basic applied research projects on the subject of malignant melanoma in our society.

Abstract
INTRODUCTION We made a clinical study, about nutrition in seriously ill patients, which includes a typical heterogeneous group of critical ill patients, with/without anaemia's, that have been admitted to Intensive Care Unit, ICU. It is difficult to individualize and to generalize the relative importance of all the factors that can contribute to these anaemia's in the admission to the Unit, including nutritional deficiencies, inflammatory alterations, the immune response to aggressions, inmunitary modifications and the complex relations existing between these clinic processes. OBJECTIVE Indirect valuation of the nutritional situation and anaemia's, in a typical heterogeneous group of critical ill patients. METHOD/RESULTS We studied 202 patients admitted to ICU, of varied and heterogeneous origin, classifying them in 3 groups: control, post surgery and septic group's, becoming the indirect valuation of the nutritional situation on the basis of: Global Subjective Valuation, (VGS) and the nutritional analytical determinations of total lymphocytes, albumin, and transferrin. Also we made hemogram and determinations of sideremia and ferritinemia to all of them. In 57% of the patients, we observed levels haemoglobin < 12.5 g/dl, basically in the post surgery groups, 68 patients and septic group's, 10 patients. And with levels haemoglobin < 10 g/dl, in 25 patient's (12.3%). There were 87 patients, 23 of them in the control group's, 58 in the post surgery and 5 septic group's, with levels haemoglobin > 12.5 g/dl. Regarding the nutritional prognoses indicators, (VGS + nutritional profile), in the control group's, they did not present anaemia nor analytical clinical under nourishment, in the post surgery group's, anaemia and slight under nourishment and in the septic group's, anaemia and moderate under nourishment. There were significant differences between the surgery and septic group and control group's, in values of haemoglobin, iron, total lymphocytes, transferrin and albumin. A statistical correlation between sideremia and albumin was significative. (Spearman's Rho 0,277). CONCLUSIONS The evaluation of the anaemia and nutritional valuation. and the ferroterapic treatment, as immune-nutrient, can be beneficial for the integrity of the immune system and its defense's abilities against the aggressions in critically ills.

Abstract
The European Biomedicine and Health (BIOMED-2) Concerted Action Project BMH4-CT98-3936 has defined standardized protocols for polymerase chain reaction (PCR) amplification of different loci of the T-cell receptor (TCR) and immunoglobulin (Ig) genes with a view to achieving greater sensitivity and specificity in the assessment of clonality of lymphoid neoplasms. To assess T-cell clonality, analysis of TCRbeta gene and TCRdelta rearrangements (useful in cases of Tgammadelta + cell neoplasms) is proposed alongside that of TCRgamma. For analysis of B-cell clonality, along with the framework (FR) III segment of the IgH gene, other segments are studied (FRI, FRII) in addition to Igl and Igk genes or incomplete DJ rearrangements of the IgH gene and the k deleting element. The results of the amplification are read using automatic reading systems (GeneScan) or using a heteroduplex system.

Abstract
BACKGROUND Vulvodynia is a fairly common dermatological symptom that often interferes with the personal, social and working activities of affected women and results in a significant loss of their quality of life. It is a persistent and tedious clinical disorder which is often resistant to conventional treatments. OBJECTIVES The aim of this study is to evaluate the main clinical signs, associated psychopathological disorders and outcome after antidepressant treatment of patients with vulvodynia. METHODS Eighty patients were included. Clinical characteristics and psychopathological profiles were determined by appropriate instruments. The improvement of clinical symptoms after combined antidepressant drug therapy was also evaluated. RESULTS Pain (70%), burning (63.7%), dyspareunia (57.5%) and stinging (56.2%) were the most commonly reported symptoms. Most patients (56.5%) showed anxiety, and 52.2% of them were reported as having a depression disorder. When evaluated by psychometric tools, 81.4% of patients scored >150 on the Life Event Scale, which means a risk >50% of suffering an illness in the near future, and patients' scores in the Dermatology Life Quality Index showed higher values than the mean of the Spanish validation group. After 6 months of combined treatment with escitalopram (10-20 mg/day), perfenazine (2-4 mg/day) and amytriptiline (10 mg/day), a complete remission of the clinical symptoms was achieved in 41% of patients. In contrast, only 12% of patients who did not follow drug treatment reported a complete resolution of the clinical symptoms. CONCLUSIONS Our results seem to confirm that vulvodynia is associated with psychiatric co-morbidity such as stress and depression. The study highlights that the psychiatric treatment may be a useful option to improve clinical symptoms. Whether these patients should be evaluated for depression or be referred to a psychiatrist, remains to be investigated.

Abstract
Eccrine angiomatous hamartoma (EAH) is a lesion that tends to appear as a plaque or nodular single lesion that may be painful and/or hyperhidrotic. Histopathologically, EAH is manifested by lobules of mature eccrine glands and ducts closely associated with well-differentiated, thin-walled blood vessels. Rarely, EAH can present as a macular hyperhidrotic lesion following a segmental distribution.

Abstract
The effect of kraft mill sludge addition (25 to 75 ton/ha) to soil derived from volcanic ashes (Andisol) on wheat (Triticum aestivum L.cv. Puken) biomass production, and in the nutrient absorption by the plants was evaluated. Respiration activity and seed germination tests were carried out on the soil/sludge mixtures, in order to evaluate possible toxic effects due to the sludge addition to the soil. Soil without sludge was used as a control treatment. The plants were grown in a greenhouse (25 degrees C, 14 h-photoperiod) during 120 days, then the plants were collected and dried at 65 degrees C for 72 h for the determination of biomass production (root and aerial) and analyzed for mineral content (Ca, Mg, K and P). The mixtures of soil/sludge showed no toxicity. Seed germination and respiration activity increased with the increment of the sludge. The accumulated CO2 in the soil without sludge was 41.66 mg CO2/100; this value shows a low microbial activity. The biomass increased with the increment of sludge addition to the soil and five times more biomass was obtained when 75 ton/ha sludge was added to the soil. The nutrient absorption efficiency was also improved with the sludge addition.

Abstract
The expression of receptor for androgen (AR), oestrogen alpha and beta (ERalpha and ERbeta) and progesterone (PR) was examined immunohistochemically in canine prostate specimens (normal, hyperplastic, inflamed [prostatitis] or neoplastic). AR immunolabelling was seen in 100% of epithelial cells of normal and hyperplastic tissue, the corresponding figures for inflamed and carcinomatous tissue being 74% and 65%, respectively. ERalpha labelling was seen in 85% of epithelial cells in normal prostate glands, the corresponding figures for hyperplastic, inflamed and neoplastic glands being 35%, 22% and 12%, respectively. ERbeta labelling was seen in 85% of epithelial cells of normal glands and in about 70% of such cells in glands showing pathological changes. On the other hand, PR expression (weak) in normal glands was observed in fewer epithelial cells (44%) than in hyperplastic (70%), inflamed (62%) or neoplastic (64%) glands.

Abstract
Infection with human immunodeficiency virus (HIV) increases the risk of developing non-Hodgkin lymphoma. Plasmablastic lymphoma (PBL) is a rare variant of diffuse large cell lymphoma that often involves the oral cavity of HIV+ patients. It is characterized by immunoblastic morphology and plasma cell phenotype. Cutaneous involvement in PBL appears to be rare. We report a 44-year-old man with AIDS and Kaposi sarcoma (KS) previously treated with doxorubicin who, following treatment with highly active antiretroviral therapy, developed an erythematous infiltrated nodule on the right arm. Histology showed subcutaneous fat necrosis and clusters of atypical large plasma cells (plasmablastic cells). Immunohistochemistry revealed lambda light chain restriction. Epstein-Barr virus (EBV) mRNA was detected by in situ hybridization within the plasmablastic cells. Polymerase chain reaction amplification with specific primers for human herpesvirus 8 (HHV-8) performed on the skin biopsy specimen detected a specific band. A complete screening (bone marrow biopsy, computed tomographic scan, radiological survey) disclosed no abnormalities. The lesion resolved spontaneously after 3 months. Two years later an infiltrated plaque developed on the abdominal wall. The clinical and histopathological features of this new lesion were similar to those observed 2 years previously. No evidence of extracutaneous involvement was detected. The lesion again resolved spontaneously after 25 days. PBL may be seen in patients with transplants or receiving chemotherapy, but is usually observed in patients with advanced AIDS. The observation of recurrent self-healing EBV- and HHV-8-associated cutaneous monoclonal plasmablastic infiltrates, in a patient with AIDS and KS, expands the clinical spectrum of AIDS-associated plasmablastic lymphoproliferative disorders.

Abstract
Mycobacterium ulcerans infection causes a skin disease known as Buruli ulcer (BU), a disorder manifested usually as a solitary and painless nodule or papule that progresses to massive necrotizing destruction and cutaneous ulceration. When healing occurs, it often results in disabling deformities. Buruli ulcer is considered the third most common mycobacterial disease in immunocompetent people, after tuberculosis and leprosy. Although the emergence of Buruli ulcer in Western African countries over the past decade has been dramatic, it has been scarcely reported in industrialized countries. We report a patient from Equatorial Guinea who was human immunodeficiency virus-positive, presenting aggressive and multifocal BU associated with an underlying destructive osteomyelitis, in which only an aggressive surgical approach yielded to a resolution of the disease. In a global world, with increasing migratory population fluxes, an increased awareness of dermatologists regarding the clinical, histopathological and microbiological features of BU is important in order to avoid significant delays in diagnosis and treatment.

Abstract
The presence of a dominant B- or T-cell clone is an important diagnostic criterion for distinguishing cutaneous lymphomas from lymphoid reactive infiltrates. Rarely, a combined B- and T-cell rearrangement can be detected from a single sample. In such instances, genotypic analysis does not permit differentiation of the coexistence of a T- and B-cell lymphoma from a single clone harbouring a monoclonal rearrangement for both immunoglobulin heavy chain and T-cell receptor genes. We herein report a case of a skin tumour consistent with a dense cutaneous lymphoid infiltrate showing a double prominent B- and T-cell component. A dual B- and T-cell clonality was detected by polymerase chain reaction from whole-tissue DNA sample. Genotypic analysis with DNA, obtained after laser-assisted microdissection from the B-cell population, again showed both T- and B-cell monoclonal rearrangements. Conversely, the microdissected T-cell population did not reveal a clonal pattern. The diagnosis of cutaneous B-cell lymphoma with a dual B- and T-cell genotype was established. This description illustrates the diagnostic usefulness of laser-capture microdissection in cutaneous lymphomas presenting dual genotype.

Abstract
Antibiotic resistance in clinical isolates of Salmonella typhimurium has steadily risen in recent years. Some of the resistance genes may be carried into integrons. In this study, integrons, both from 10 epidemiologically related and unrelated S. typhimurium clinical isolates, were characterized, showing that epidemiologically different strains can carry the same integron, and that epidemiologically related strain can carry different integrons. Among the resistance genes detected in this study were genes encoding b-lactamases (bla(oxa-30) in two strains, and bla(pse-1) in five strains, one of which was carrying this cassette in two different integrons); aminoglycoside-modifying enzymes (aadA2 in four strains, one of which was carrying this cassette in two different integrons, and aadA1 in six strains); as well dihydrofolate reductases (dfrAI in three strains).

Abstract
INTRODUCTION Benign recurrent intrahepatic cholestasis (BRIC) is a rare autosomal-crecessive or sporadic disorder, characterized by repeated episodes of unexplained cholestasis followed by prolonged asymptomatic periods. CASE REPORT We present two male patients aged 12 and 15 years old who initially presented cholestasis and who had no family history of liver or biliary disease. Typically, alkaline phosphatase and bilirubin levels were elevated, with a slight increase in transaminases and gamma-glutamyltransferase. In both patients biliary tract disease was ruled out by endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiography while no significant abnormalities of the liver parenchyma were found on liver biopsy. Early treatment with ursodeoxycholic acid (UDCA) reduced the duration of the cholestasis episode compared with that of other episodes in which the patient had received other treatment or the treatment was late (1 or 2 months vs 4 months in patient 1 and 1-3 months vs 5 months in patient 2, respectively). DISCUSSION Consensus is lacking on the treatment of BRIC although several treatment have been used. UDCA could be effective in increasing bile acid secretion and in reducing serum bilirubin levels. In the two patients described, the initial dosage was 15 mg/kg/day, which was subsequently maintained at 6 mg/kg/day, which was subsequently maintained 6 mg/kg/day until biochemical parameters returned to normal. Nevertheless, larger studies are required to confirm that UDA shortens episodes of cholestasis in BRIC.

Abstract
Large series of patients with Sézary syndrome (SS), the leukemic variant of cutaneous T-cell lymphoma (CTCL), have been reported infrequently because of its low incidence. Here we recorded several clinical, histopathological and immunophenotypical features of 29 cases of leukemic CTCL patients from four Dermatology Departments of Catalonia, Spain, and analyzed their prognostic value. Clinical data included sex, age, delay of SS diagnosis, previous diagnosis of lymphoma, B-symptoms, type of skin lesions, peripheral adenopathy, histologic evaluation of lymph node biopsy, visceral involvement, percentage of circulating Sézary cells, serum LDH and beta-2-microglobulin levels, first treatment and response, disease-free interval, further therapies and survival. Histopathological data examined were epidermotropism, depth and thickness of the infiltrate, cell size, adnexal involvement, presence of granuloma, eosinophils and plasma cells, mitotic rate. The percentage of CD45Ro, CD43, CD20, CD30 and CD8 positive dermal cells were also recorded. Survival showed a mean actuarial risk of 57% at 3 years and 38% at 5 years, with a median survival of 48 months. Analysis of actuarial survival demonstrated as following as features linked with a bad prognosis: fast evolution of the disease (from symptoms onset up to diagnosis) (p = 0.0274) raised levels of serum lactate dehydrogenase (p = 0.0379) and beta-2-microglobulin (p = 0.0151), the latter being the most important prognostic factor. In conclusion although SS had been traditionally considered as a low-grade lymphoma, the present study agrees with the recent classification rating SS as an aggressive type of CTCL with a poor prognosis. Our results show that some simple clinical and blood test data can be useful as prognostic indicators in this disease.

Abstract
BACKGROUND Primary cutaneous marginal zone B-cell lymphoma (MZCL) has recently been described. Differentiation from follicular centre cell lymphomas and lymphocytomas is often difficult due to insufficient experience and a lack of large series of patients. OBJECTIVES To characterize primary cutaneous MZCL better, we report clinical, histopathological, immunophenotypic and molecular genetics features in a series of 22 patients. METHODS All patients were treated and followed up at the same institution. Diagnosis of MZCL was based on the World Health Organization classification criteria. All samples were routinely tested with a wide panel of monoclonal antibodies. DNA was extracted from every sample following standard methods. IgH rearrangement and t(14;18)(q32;q21) studies were performed in all samples. RESULTS Twenty-two patients (20 men, two women; mean age 50 years, range 24-77) were included. The mean follow-up was 43 months. Seventy per cent of patients presented with characteristic skin lesions on the trunk or extremities, consisting of deep red to violaceous infiltrated plaques, nodules or tumours frequently surrounded by diffuse or annular erythema. Four patients presented with lesions on the head and neck area. Two patients had disseminated skin lesions. The main histopathological features were non-epidermotropic, dense lymphocytic infiltrates mainly distributed in a nodular pattern. Adnexal involvement was usually present, with eventual formation of lymphoepithelial complexes. Cytologically, the infiltrate was polymorphous with marginal zone B cells and B-monocytoid cells. Blastoid CD30+ cells were often observed. Colonized reactive germinal centres and lymphoplasmocytoid differentiation were frequently present. Neoplastic cells were CD20+, CD79a+, CD5- and CD10-. Monotypic expression of light chains was observed in 18 cases (13 kappa; five lambda). Clonal IgH rearrangements were detected in 14 cases. The bcl-2 mutation t(14;18)(q32;q21) was demonstrated in two cases. Most patients were treated with local radiotherapy. Complete response rate with this approach was 100%. Six patients (27%) had skin recurrences from 6 months to 8 years after first treatment. Five patients (23%) had extracutaneous involvement. Two of them had a large cell transformation and one died of lymphoma. Three of four patients with head and neck presentation developed extracutaneous disease. CONCLUSIONS MZCL appears to be a well recognizable entity, clinically, histologically and immunophenotypically. Although prognosis is generally good, the disease has potential for skin as well as extracutaneous recurrences. Large cell transformation and head and neck presentation may be associated with a worse prognosis.

Abstract
We describe a 76-year-old woman who presented persistent generalized pruritus as the only cutaneous manifestation of a cutaneous T-cell lymphoma (mycosis fungoides). No cutaneous lesions were observed throughout the patient's course. Skin biopsies obtained from normal-looking pruritic skin revealed a discrete perivascular lymphocytic infiltrate in the upper dermis and focal intraepidermal clusters of atypical lymphoid cells (Pautrier's microabscesses). PCR analysis of TCR-gamma gene disclosed a monoclonal T-cell rearrangement. Sequencing of the PCR monoclonal product identified the J(8)V(2)C(2) TCR gene rearrangement. This observation illustrates the existence of a peculiar and exceedingly rare form of mycosis fungoides characterized only by persistent pruritus unresponsive to several therapeutic approaches. The diagnostic difficulties of this rare variant are stressed.
