Abstract
Therapeutic management of pustular psoriasis remains a challenge despite the rapid advance in psoriasis research and the development of drugs, especially biologics. Treatment guidelines have been established for pustular psoriasis, but no controlled studies are present for juvenile pustular psoriasis (JPP). Search of the literature reveals that current evidence of JPP treatment is limited to case reports and case series. Among the conventional drugs for JPP, oral retinoid is the most commonly used, yet concerns for growth disturbance exist. Cyclosporine and methotrexate have also been administered as first-line treatment. Etanercept is the first biological agent approved for juvenile plaque psoriasis, followed by adalimumab. However, infliximab is usually recommended for JPP because of the rapidity of onset, despite not being approved for use in pediatric psoriasis patients. More recently, secukinumab, ixekizumab, brodalumab, guselkumab, and risankizumab have been approved for adult pustular psoriasis in selected countries. Controlled studies are needed to prove the efficacy and long-term safety of the therapeutic treatments currently used for JPP.

Abstract
Psoriasis is a chronic, immune-mediated, inflammatory skin disease, affecting 1-3% of the white population. Although the existence of two psoriasis incidence peaks has been suggested (one in adolescence before 20 years of age and another in adulthood), its onset may occur at any age, including childhood and adolescence, in which the incidence is now estimated at 40.8 per 100,000. As for adult psoriasis, pediatric psoriasis has recently been associated with obesity, metabolic syndrome, increased waist circumference percentiles and metabolic laboratory abnormalities, warranting early monitoring and lifestyle modifications. In addition, due to psoriasis' chronic nature and frequently occurring relapses, psoriatic patients tend to have an impaired quality of life, often requiring long-term treatment. Therefore, education of both pediatric patients and their parents is essential to successful and safe disease management. Given the lack of officially approved therapies, the very limited evidence-based data from randomized controlled trials, and the absence of standardized guidelines, to date, pediatric psoriasis treatment is primarily based on published case reports, case series, guidelines for adult psoriasis, expert opinions and experience with these drugs in other pediatric disorders coming from the disciplines of rheumatology, gastroenterology and oncology. This review focuses on the use of systemic treatments in pediatric psoriasis and their specific features, analyzing the few literature evidences available, expanding the treatment repertoire and guiding dermatologists in better managing of recalcitrant pediatric psoriasis.

Abstract
Psoriasis is a common yet complex inflammatory dermatosis that may be seen in infants, children, and adolescents. The clinical presentation and course may be quite variable, and while patients with mild disease are often easily managed, those with recalcitrant or more severe disease often present a therapeutic dilemma given the number of therapies available and the relative lack of data on the efficacy and safety of use of these therapies in children. This review presents the reader with an overview of the current understanding of the pathophysiology, diagnosis, and treatment of pediatric psoriasis, with an emphasis on the available data in the literature that pertains to the use in children of currently available topical and systemic therapies, including topical corticosteroids, vitamin D analogs, phototherapy, systemic immunosuppressive medications, and biologic agents.

Abstract
Generalized pustular psoriasis (GPP) is a rare type of psoriasis and is considered the most severe variant. Infantile pustular psoriasis (IPP) is a very rare form of GPP. Severe IPP may be difficult to control and is complicated by bacterial superinfection, dehydration, and sepsis. Herein, a 2.5-month-old infant with IPP is presented, who was successfully treated with systemic retinoid therapy, which appears to be a safe and effective option for this challenging pustular eruption of childhood.

Abstract
We report a 2-year-old girl with diffuse pustular eruptions occurring in close association with respiratory tract infections. The pustular eruption had different clinical characteristics over time, evolving from circinate to von Zumbush pustular psoriasis, and finally to subcorneal pustular dermatosis. Treatment with acitretin 1 mg/kg/day gave good results. A relapse showing striking clinical characteristics of subcorneal pustular dermatosis was treated with dapsone (1 mg/kg/day) followed by ultraviolet B-narrowband (UV-B-NB) phototherapy. The patient subsequently had several relapses over 1 year, which were well controlled with short cycles of UV-B-NB. This patient's findings demonstrate that pustular eruptions can vary over time, assuming clearly different clinical patterns, and highlight the difficulty of classifying pustular eruptions as separate diseases.

Abstract
Reactive angioendotheliomatosis (RAE) is a rare condition characterized by cutaneous vascular proliferation that usually occurs in patients with diverse types of coexistent systemic disease. Although intravascular proliferation of endothelial cells has been considered to be the key histologic feature in RAE, other patterns of vascular proliferation have also been described. We reviewed the clinicopathologic features in 15 cases of RAE. The study group comprised eight males and seven females with an age range of 47-88 years (median 65 years). Eleven patients had coexistent systemic disease: renal disease (six patients, including three post renal transplantation); valvular cardiac disease (two patients); one patient each had alcoholic cirrhosis, glioblastoma multiforme (on chemotherapy), and rheumatoid arthritis/polymyalgia rheumatica. Six patients were iatrogenically immunosuppressed at the onset of the skin lesions. The clinical appearance included multiple erythematous macules, plaques, tumors, and ulcerated lesions, with a wide distribution but a propensity to involve limbs. Lesions had been present for 1 month to 4 years (median 4 months). Lesions resolved in four cases, improved in two cases, remained static in one case, and progressed in four cases. Two cases were recent and follow-up was not available in two other cases. Three patients died of their coexistent systemic disease with resolution, improvement, and progression of lesions, respectively. All lesions were characterized histologically by a proliferation of capillaries in the dermis, with variably diffuse (seven cases), lobular (six cases), or mixed lobular and diffuse patterns (two cases). There was marked intercase and intracase heterogeneity in histologic features. Common features included fibrin microthrombi (nine cases), reactive (fasciitis-like) dermal alterations (seven cases), and foci of epithelioid endothelium (four cases). Four of 10 cases tested showed positive immunohistochemical staining for HHV-8 latent nuclear antigen in lesional endothelial cell nuclei. This study suggests that RAE has a broader clinicopathologic spectrum than previously described. The pathogenesis of this rare disorder is unknown, but it is likely that immunologic factors play a role.

Abstract
Psoriasis often presents in childhood. The diagnosis may be challenging if the disease is mild or the presentation is atypical. All of the forms recognised in adults are encountered in childhood (plaque, guttate, erythrodermic and pustular). Guttate and flexural forms are particularly common in children. Successful management requires education of the child and parents regarding the course of the disease and treatment options. Environmental triggers should be sought out and eliminated where possible. Most patients respond to topical treatment with emollients, coal tar, anthralin (dithranol) or calcipotriol. Treatment is tailored according to patient age, extent and distibution of psoriasis. For those who fail to respond, daycare or inpatient care is appropriate. Phototherapy with UVB may be combined with topical agents. Systemic therapy is required in a minority, usually those with resistant or erythrodermic disease, pustular psoriasis and arthropathic psoriasis. Retinoids are probably the systemic agent of choice. There are few data regarding the use of methotrexate or cyclosporin in childhood psoriais.

Abstract
Annular pustular psoriasis (APP) is a rare form of pustular psoriasis with a chronic recurrent course and good prognosis. We report three cases of APP in children, two of whom were siblings. Review of the medical literature reveals that a disproportionately high percentage of cases of APP occur in children. In some cases topical therapy can clear the condition, although in severe or recalcitrant disease, systemic therapy may be necessary.

Abstract
A diffuse xanthomatous infiltration was detected on a biopsy of the hyperpigmented patches in a 40-year-old man with POEMS (Polyneuropathy, Organomegaly, Endocrinopathy, M-protein, Skin changes) syndrome. Multiple biopsies of the hyperpigmented patches showed diffuse or perivascular foamy histiocytes in the upper and mid dermis, a sparse infiltrate of lymphocytes, fibrosis, hyperpigmentation of the basal layer, and capillary proliferation. The foamy cells were positive for periodic acid-Schiff (PAS) with diastase, oil red-O, and CD68. To our knowledge, this is the first case with foamy histiocytes without xanthomatous-appearing skin lesions in POEMS syndrome. It would be worth searching for xanthomatous histiocytes in the hyperpigmented skin of patients with POEMS syndrome.

Abstract
It is not unusual for psoriasis to start in childhood although a mild or atypical presentation sometimes makes it difficult to establish a confident diagnosis at this age. All adult forms occur but flexural psoriasis and guttate psoriasis are particularly common. Management involves education of the child and parents concerning the nature of psoriasis and the effects of treatment. Genetic counselling may be provided if needed based on population data. Environmental triggers of psoriasis should be sought particularly infection. Psoriasis can usually be treated effectively in children with topical agents including emollients, coal tar, corticosteroids, dithranol and calcipotriol according to age and the sites affected. In those who do not respond, consideration should be given first to day care or in-patient treatment which may be combined with UVB phototherapy. Systemic therapy should be used only under extreme circumstances such as resistant erythrodermic, pustular or arthropathic psoriasis. There are no controlled trials in this age group but the most experience has been with retinoids which are probably the second-line drug of choice for children. Methotrexate and cyclosporin appear to be effective in children but more efficacy and safety data are required.

Abstract
This study analyzed data from treatments of 385 cases of generalized pustular psoriasis (GPP) from 325 hospitals in Japan. Retinoid treatment was effective in 84.1% of patients, methotrexate in 76.2%, cyclosporine in 71.2%, oral PUVA therapy in 45.7%, and tonsillectomy in 16.7%. Short-term therapy with systemic corticosteroid for GPP during only the phase with severe systemic clinical findings may be also effective (75.4%). However, these treatments for GPP each differed in clinical effects, prognosis, and side effects. These findings may be useful in creating guidelines for treatment of generalized pustular psoriasis. Further studies based on these specific clinical effects are necessary.

Abstract
Reactive cutaneous angioendotheliomatosis (RCA) is an uncommon benign disease characterized by intravascular proliferation of endothelial cells. The observation of RCA in infants is exceedingly rare. We describe a case of RCA in a 3-month-old infant. The lesions were characterized by six small purpuric papules (1-2 mm in diameter), distributed on the thighs and neck. The general condition of the patient was good, with no lymphadenopathy, systemic involvement, or fever. The histopathologic features of a papule were characterized by the presence of cohesive aggregates of large mononucleated cells protruding into the lumina of dilated vessels and filling some of them completely. Neither an inflammatory infiltrate nor a proliferation of pericytes were present around blood vessels. Intravascular proliferating cells demonstrated positive staining for Ulex europaeus agglutinin 1 (UEA-1) and for Factor VIII-RA and CD34 antigens. The course of the disease was unremarkable with persistence of the lesions for 8 months; no treatment was started.

Abstract
The incidence of many skin diseases peak in adulthood, and these disorders may be difficult to recognize when they do present in childhood. Their clinical features may be distinct in pediatric patients, and they may be managed differently in children as compared to adults. Therefore, it is important that dermatologists are able to identify "adult" skin disease in the pediatric patient, and know how to appropriately manage these problems in young patients. The epidemiology, clinical features, differential diagnosis, and management of the following "adult" skin diseases in children are reviewed: psoriasis, lichen planus, rosacea, Sweet's syndrome, and mucosis fungoides. Distinctive features of lichen sclerosus and immunobullous diseases in childhood will also be briefly discussed.

Abstract
Angioendotheliomatosis is an uncommon disease characterized histologically by proliferation of cells within vascular lumina with secondary intravascular thrombi resulting in obliteration of the involved vessels. While angioendotheliomatosis was initially thought to be a single disease entity, recent studies show that the disease may be divided into benign (reactive) and malignant variants, with the malignant variant representing intravascular malignant lymphoma. The reactive variant is rare, with only 16 cases reported in the literature, and is characterized histologically by proliferating endothelial cells within vessel lumina. In this report we present a case of reactive angioendotheliomatosis and review the literature on this rare entity.

Abstract
We treated childhood psoriasis with methotrexate (MTX) in seven children (4 boys, 3 girls) over 7.5 years. Their ages and duration of disease varied from 3.5 to 16 years (mean 12.14 yrs) and 4.8 months to 5 years (mean 2.2 yrs), respectively. Psoriatic erythroderma was seen in three patients, generalized pustular psoriasis in two, recalcitrant psoriasis and psoriatic arthropathy in one each. Pre-MTX liver biopsy performed in 4 children showed grade I changes. Methotrexate was given in a single weekly oral dose of 3.75 to 25 mg (mean 16.6 mg). The duration of treatment necessary to control the disease varied from 6 to 10 weeks (mean 7.9 wks). Total duration of MTX therapy was 31.2 to 46.4 weeks (mean 38.8 wks). Posttherapy disease-free interval ranged between 14.4 and 16.8 weeks (mean 15.5 wks). Follow-up after withdrawal of MTX was 16 to 28 weeks (mean 22.3 wks). Total cumulative MTX dose ranged from 390 to 960 mg (mean 683.6 mg). Side effects were nausea and vomiting in three patients.
