Abstract Cutaneous manifestations occur in the course of hematologic malignancies and precede, accompany or occur late in relation to the diagnosis. They result from paraneoplastic phenomena, tumor infiltrations, immunosuppression resulting from the hematologic disease itself or its treatment. The dermatologist must be aware of these conditions that may be helpful both in the diagnosis of the underlying disease and in reducing patient morbidity. This review (part II) addresses the paraneoplastic dermatological changes associated with systemic hematologic malignancies. precede phenomena infiltrations treatment morbidity part II

Abstract Cutaneous manifestations occur during the course of hematologic malignancies and precede, follow, or are late events in relation to the diagnosis. They result from paraneoplastic phenomena, tumor infiltrations, and immunosuppression resulting from the hematologic neoplasia itself or its treatment. The dermatologist must be aware of these conditions, which can help both in the diagnosis of the underlying disease and in the reduction of patient morbidity. This review (part I) addresses skin lesions associated with direct infiltration by systemic hematologic malignancies. precede follow phenomena infiltrations treatment conditions morbidity part I

Abstract: Background: Urticarias are frequent diseases, with 15% to 20% of the population presenting at least one acute episode in their lifetime. Urticaria are classified in acute ( ≤ 6 weeks) or chronic (> 6 weeks). They may be induced or spontaneous. Objectives: To verify the diagnostic and therapeutic recommendations in chronic spontaneous urticaria (CSU), according to the experience of Brazilian experts, regarding the available guidelines (international and US). Methods: A questionnaire was sent to Brazilian experts, with questions concerning diagnostic and therapeutic recommendations for CSU in adults. Results: Sixteen Brazilian experts answered the questionnaire related to diagnosis and therapy of CSU in adults and data were analyzed. Final text was written, considering the available guidelines (International and US), adapted to the medical practices in Brazil. Diagnostic work up in CSU is rarely necessary. Biopsy of skin lesion and histopathology may be indicated to rule out other diseases, such as, urticarial vasculitis. Other laboratory tests, such as complete blood count, CRP, ESR and thyroid screening. Treatment of CSU includes second-generation anti-histamines (sgAH) at licensed doses, sgAH two, three to fourfold doses (non-licensed) and omalizumab. Other drugs, such as, cyclosporine, immunomodulatory drugs and immunosuppressants may be indicated (non-licensed and with limited scientific evidence). Conclusions: Most of the Brazilian experts in this study partially agreed with the diagnostic and therapeutic recommendations of the International and US guidelines. They agreed with the use of sgAH at licensed doses. Increase in the dose to fourfold of sgAH may be suggested with restrictions, due to its non-licensed dose. Sedating anti-histamines, as suggested by the US guideline, are indicated by some of the Brazilian experts, due to its availability. Adaptations are mandatory in the treatment of CSU, due to scarce or lack of other therapeutic resources in the public health system in Brazil, such as omalizumab or cyclosporine.

FUNDAMENTO: Siringoma é tumor anexial benigno do ducto sudoríparo écrino cujo tratamento é realizado por diversas modalidades cirúrgicas com resultados variáveis. OBJETIVO: 1. Relatar a experiência no tratamento cirúrgico de siringomas periorbitários mediante excisão com a tesoura oftalmológica de Castroviejo, seguida pela cicatrização por segunda intenção. 2. Apresentar revisão da literatura com enfoque no aspecto terapêutico. MATERIAL E MÉTODOS: Em 68 meses foram tratados 38 pacientes com siringomas periorbitários. Realizada a exérese cirúrgica com tesoura oftalmológica de Castroviejo seguida pela cicatrização por segunda intenção. Realizadas avaliações sete, 30 e 90 dias após a cirurgia. O seguimento variou entre três e 62 meses, com média de 33 meses. RESULTADOS: Dos 38 pacientes tratados, 63,1% tiveram resultado ótimo, 31,6% bom e 5,3% regular. A única complicação imediata observada foi edema, e as tardias foram: hipocromia (12 casos), cicatriz deprimida (um caso) e hipertrófica (um caso). Não ocorreram recidivas no período observado. CONCLUSÕES: O tratamento dos siringomas periorbitários mediante exérese cirúrgica com tesoura oftalmológica de Castroviejo, seguida pela cicatrização por segunda intenção, constitui procedimento ambulatorial de baixo custo e fácil execução. Proporciona resultados satisfatórios, sem recidivas, apesar da possibilidade de ocorrer hipocromia transitória.

BACKGROUND: Syringomas are benign adnexal tumors from intraepidermal eccrine ducts, treated by diverse surgical modalities with variable results. OBJECTIVES: 1. To report our experience in surgical treatment of multiple periorbital syringomas excised by Castroviejo scissors followed by healing by secondary intention. 2. To present a literature review with emphasis on therapeutic aspects. MATERIAL AND METHOD: During 68 months we treated 38 cases of periorbital syringoma. All of them were submitted to surgical excision using Castroviejo scissors, followed by healing by secondary intention. Evaluation was done 7, 30 and 90 days after surgery. The mean follow-up period was 33 months, ranging from 3 to 62 months. RESULTS: The results were excellent in 24 patients (63.1%), good in 12 patients (31.6%) and regular in two patients (5.3%). The only immediate complication observed was edema; late complications were hypochromia (12 patients), depressed scar (one patient) and hypertrophic scar (one patient). Recurrences were not observed during the follow-up period. CONCLUSIONS: We concluded from our results that excision of periorbital syringomas by Castroviejo scissors followed by healing by secondary intention is a low cost, straightforward outpatient procedure. Results are good, with no recurrences, although transient hypochromia may occur.
