    Notes: There is a wide variety of topical or surgical treatment options for molluscum contagiosum (MC). However, treatment in young or anxious children is difficult, time-consuming and often painful. We studied the topical efficacy and tolerance of imiquimod, a topical immune-response modifier, which stimulates the production of interferon-αand other cytokines in children with MC. In an open-label, follow-up trial, imiquimod 5% cream was applied three times a week for 16 weeks to 15 children aged 4–11 years with multiple MC. Nine of 13 children (69%) who completed treatment responded. Two patients (15%) showed a complete remission, and seven (54%) had a partial response, with a remarkable reduction of the MC lesions. Four children (31%) showed stable or progressive disease. In three children (23%) with partial remission, the number of mollusca were considerably reduced, thus avoiding surgical treatment. In general, the treatment was well-tolerated, without systemic side-effects. Local side-effects included erythema (85%), itching (75%), burning sensations (23%) and pain (11%). Three children (23%) discontinued treatment because of local side-effects. The results of this study suggest that imiquimod 5% cream is a useful new treatment option for MC in children, especially in severe cases. The dosing schedule and length of treatment requires further evaluation.

    Notes: Severe generalized nodular and bullous mastocytosis of the xanthelasmoid type is described in a 7-month-old boy. Reddish to yellowish-brown xanthelasmoid papules and nodules first developed in the inguinal region a few weeks after birth and then progressively spread to cover nearly the entire body surface. There was severe pruritus and recurrent episodes of blistering. The diagnosis of cutaneous mastocytosis of the xanthelasmoid type with subepidermal bullae was confirmed by skin biopsies showing solid and deeply penetrating infiltrates of metachromatic mast cells under light and electron microscopy. Systemic involvement of other organs, however, was excluded by bone scintigraphy, abdominal ultrasound, bone marrow aspiration and echocardiography. The extensive skin involvement was reflected in highly elevated urinary levels of histamine (263·4 μg L−1) and its metabolite N-methylimidazole acetic acid (20·8 mg L−1). The patient was systematically well and received only symptomatic treatment. Over a period of 1 year, the condition gradually improved, and the skin lesions began to flatten and regress.

    Notes: Schnitzler's syndrome is a distinct disease entity characterized by the association of chronic urticaria, intermittent fever, arthralgia, elevated erythrocyte sedimentation rate and IgM macroglobulin-aemia. We report a patient with the same symptoms, but a monoclonal IgG instead of IgM gammopathy. Histological examination of the urticarial lesions showed signs of mild leucocyto-clastic vasculitis. Except for the different class of the monoclonal immunoglobulin, the clinical symptoms, laboratory findings and histology in this patient were identical with those in classical Schnitzler's syndrome. IgG and IgM paraproteins may be equivalent with regard to the putative pathophysiology of the disease process in Schnitzler's syndrome. We therefore suggest that the spectrum of Schnitzler's syndrome is expanded to include patients with chronic urticaria and monoclonal IgG gammopathy, as a closely related variant.

    Notes: Alternative activation of macrophages, induced by Th2 cytokines and glucocorticoids, is essential for the proper functioning of anti-inflammatory immune reactions. To this end, alternatively activated macrophages (aaMΦ) express a not yet fully unravelled set of genes including cytokines such as alternative macrophage activation-associated CC-chemokine (AMAC)-1 and pattern recognition molecules such as the scavenger receptor CD163. In order to further characterize the molecular repertoire of aaMΦ, differential gene expression was analyzed by combining subtractive suppression cloning and differential hybridization. We show here that aaMΦ induced by interleukin (IL)-4 overexpress the prototype extracellular matrix (ECM) protein fibronectin on the mRNA and protein level. This overall increase is accompanied by a shift in fibronectin splice variants from an embryonic to a mature pattern. In addition, the expression of another ECM protein, βIG-H3, is also upregulated by IL-4 in aaMΦ. In contrast to IL-4 and in line with its inhibitory effect on wound healing, dexamethasone exerts a strongly suppressive effect on fibronectin and βIG-H3 expression. In conclusion, overexpression of ECM proteins induced by IL-4 in macrophages suggests that aaMΦ may be involved in ECM deposition and tissue remodelling during the healing phase of acute inflammatory reactions and in chronic inflammatory diseases.

    Notes: Background  Cutaneous T-cell lymphoma (CTCL) is a slowly progressive malignancy for which there is no cure. Therefore, accurate prediction of prognosis is important for the conduct of clinical trials and for counselling of individuals.Objectives  To improve prediction of survival in patients with CTCL.Methods  Prognostic factors including tumour–node–metastasis (TNM) criteria and the CTCL Severity Index (CTCL-SI) were analysed using a Weibull model for multivariate analysis in a sample of 62 patients with classical CTCL (mycosis fungoides and Sézary syndrome). The Brier score was used to quantify the quality of individual prediction.Results  Estimated 5-year survival rate (SR5) differed according to TNM stage: stage IA, 100% (95% confidence interval 70–100%); IB–III, 86% (73–100%); IVA, 54% (32–91%); IVB, 0% (0–52%). In a multivariate analysis, two independent prognostic factors were identified: lymph node (P = 0·036) and blood involvement (P = 0·015). A probability of survival model showed correlation of CTCL-SI with survival in patients with CTCL-SI 〉 20 according to the following formula: SR5 = 124–2 × (CTCL-SI)%. Calibration of SR5 against CTCL-SI-independent CTCL subsets revealed underestimation of Sézary syndrome. When CTCL-SI parameters were adjusted accordingly, the probability of survival model did not change significantly, while SR5 values became adequate. In addition, CTCL-SI was shown to be superior to TNM by 30% regarding individual predictive power.Conclusions  Probability of survival in CTCL can be accurately predicted by a CTCL-SI-based survival rate formula. Careful monitoring of lymph node and blood compartments and quantification by CTCL-SI are reliable tools for follow-up of patients with CTCL and allow progression-adjusted prediction of prognosis.

    Notes: We report on a 74-year-old female patient with a primary cutaneous CD20+, diffuse large cell B-cell lymphoma of the lower leg resembling a chronic non-healing leg ulcer. There was no evidence of systemic involvement on computed tomography (CT) scans of the chest, abdomen and pelvis; a slightly enlarged lymph node in the right groin showed dermatopathic lymphadenopathy on histology and immunohistochemistry. Involvement of the bone marrow and peripheral blood was ruled out by punch biopsy and fluorescent activated cell sorter (FACS) analysis of the blood, respectively. Therapeutic anti-CD20 monoclonal antibody rituximab was given at 375 mg m−2 i.v. once weekly for 7 weeks, without adverse effects, resulting in a minor improvement in the centre of the ulcerated tumour. Unfortunately, the response was not maintained, and after 7 weeks of treatment the patient started to develop new tumour lesions at the border of the ulcer. Local radiotherapy was started and combined photon and electron beam irradiation induced complete remission of the B-cell lymphoma.
