Introdução: Quelóides são tumores benignos de pele causados por alterações no processo de cicatrização de feridas. As opções terapêuticas disponíveis são diversas e a associação entre as técnicas é comumente utilizada. Métodos: Efetuámos a avaliação do tratamento combinado de ressecção cirúrgica de quelóide no lóbulo da orelha com posterior colocação de brinco de pressão utilizando êmbolos estéreis de seringas de 5 mL, que permaneceram no local durante 30 dias, combinado com injecção intralesional de corticoide aos 15 dias. Resultados: Foram avaliados cinco pacientes (3M/2F) com média de 22 anos, com quelóides recidivantes dos lóbulos auriculares tratados no Hospital Jean Bitar, estado do Pará, no ano de 2019 a 2020. O procedimento decorreu sem incidentes e o resultado estético foi considerado muito bom, sem recidiva após 6 meses Conclusão: Este procedimento cirúrgico combinado e a confecção do brinco foi considerada de baixo custo, fácil reprodutibilidade e com bom resultado estético final e boa tolerabilidade

A blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a cutaneous lymphoma derived from a plasmacytoid dendritic precursor cell that exhibits aggressive clinical behavior. Herein, we report a 46-year-old woman with a complaint of a painless nodule on the back, associated with pruritus. The nodule grew and new growths appeared over six months of evolution. The histopathological examination of one of the left upper limb lesions showed a dense lymphoid cell infiltrate with atypia in the superficial and deep dermis. Immunohistochemistry showed positivity for CD45, S-100 protein, CD123, and TCL 1. About two months after the initial evaluation, the patient was admitted to the Emergency Hospital of Marituba-PA with dyspnea. She progressed to cardiorespiratory arrest and death within 12 hours of admission. There is still no consensus for the treatment of BPDCN. Intensive therapy for acute leukemia can be useful, but allogeneic bone marrow transplantation has a greater chance of long-term survival.

BACKGROUND: describes clinical aspects of patients with chromoblastomycosis treated at the dermatology department of the Para State University. The present study aimed to describe clinical and therapeutic aspects of patients with chromoblastomycosis treated at the dermatology department of Para State University. METHODS: An observational, descriptive, case series study was performed, comprising 12 patients with the diagnosis of chromoblastomycosis. A clinical interview and a dermatological protocole were applied, classifing these patients in variables as gender, age, time of illness, type of lesion (size, shape, appearance, location and evolution), treatment and complications. Those unable to attend the clinic in person or unable to be represented by someone legally, a Term of Consent for Data Use was applied. CONCLUSIONS: most of the patients were male, rural workers, with vegetative lesions according to the classification of Carrión, graduated as moderate, with less than 10 years of evolution.

O siringocistoadenoma papílifero é uma neoplasia anexial benigna incomum, que se localiza preferencialmente no couro cabeludo e face, e está associado ao nevo sebáceo em 40% dos casos. Embora rara, a transição para carcinoma basocelular e carcinoma ductal pode ocorrer. Os autores descrevem o caso de um paciente do sexo masculino, de 7 anos de idade, com dermatose papulosa linear do pescoço desde o nascimento. Apresentava, no exame dermatológico, pápulas eritematosas, crateriformes, confluentes, dispostas em faixa, de 3 x 2 cm na região cervical. Foi realizada a exérese da lesão e o exame histopatológico demonstrou invaginação cística epidérmica e projeções papilares revestidas por epitélio glandular, com secreção de decapitação e infiltrado linfo-plasmocitário abundante. Os achados clínicos e histológicos foram compatíveis com o diagnóstico de siringocistoadenoma papílifero. Apesar da variabilidade clínica desta entidade, a histopatologia é característica e o tratamento consiste na exérese da lesão.

Introduction: Moderate and severe forms of psoriasis require phototherapy and/or systemic medications. The UVB band, with wavelength between 311 and 312nm, is called narrowband UVB (NB-UVB) and it has proven to be more beneficial for the psoriasis treatment. Goals: to characterize the group of patients with psoriasis treated with NB-UVB phototherapy, according to the clinical form, sex, phototype, and clinical evolution. Methods: All patients with psoriasis who underwent NB-UVB phototherapy between August 2016 and April 2017 were included in this study. Data on the patients were collected retrospectively. Results: During the study, 19 patients were treated with NB-UVB phototherapy, being 09 women (47%) and 10 men (53%), ages ranging from 22 to 81years. The most prevalent phototypes were III (42%) and IV (37%). Only 04 patients (21%) had guttate psoriasis and 15 (79%) had psoriasis vulgaris with variable severity. The total number of phototherapy sections, during the period evaluated, varied from 7 to 51, with an average of 25 sessions. It was observed that, 09 patients (47%) had a response beginning with up to two months of treatment. The minimum number of sections to start improvement varied from 8 to 28, with an average of 16 sessions. Conclusions: The use of NB-UVB phototherapy proved to be a safe and effective treatment, and should be considered a good therapeutic option for psoriasis.

O carcinoma de células escamosas cutâneo é resultante da proliferação maligna dos queratinócitos. Costuma surgir da evolução de lesões precursoras, mas pode crescer espontaneamente na pele normal ou cronicamente inflamada. O carcinoma de células escamosas invasivo corresponde à segunda forma mais comum de câncer da pele não melanoma e representa 20% de todas as neoplasias cutâneas. Este trabalho relata um caso clínico de carcinoma de células escamosas cutâneo, rapidamente progressivo e com metástases regionais, que mesmo com a ressecção completa e esvaziamento ganglionar, apresentou pouca resposta terapêutica e evoluiu a óbito.

Background: Dohi's Reticulated Acropigmentation is a rare autosomal dominant genodermatosis with high penetrance, characterized by small, irregular, hypo and hyperpigmented macules on the dorsal surface of the distal extremities. Case: The authors report a case of Dohi’s Reticulated Acropigmentation in a 61 years old female patient. The patient complained of spots on hands, feet and posteriorly face involvement since she was 7 years old. Conclusion: Dohi's Reticulated Acropigmentation is a rare clinical condition, which usually appear in childhood and commonly interrupt their onset before adolescence. The diagnosis is based on clinical data, physical examination and histopathological findings. The treatment is unsatisfactory and still no therapy is proposed.

An atopic breast eczema is usually bilateral, with intense pruritus and good response to corticosteroids. The differential diagnosis with mammary Paget’s disease is fundamental, mainly in unilateral clinical manifestations, since it is frequently associated to adjacent breast tumors. The aim of the present report was to present a clinical condition of an atopic breast eczema through an exuberant and unilateral clinical presentation, emphasizing the need of the differential diagnosis for malignant diseases at this location.
