RESUMO

A doença de Hailey-Hailey ou pênfigo familiar benigno é condição rara, que se caracteriza por lesões vesiculares e erosões, associadas a dor e queimação, que comprometem a qualidade de vida dos pacientes. Existem vários tratamentos tópicos e sistêmicos que podem promover temporariamente a remissão das lesões, não existindo tratamento curativo. Algumas opções de tratamento com resultados duradouros abrangem a dermoabrasão e a vaporização com laser de Erbium YAG ou CO2. Relatamos três casos de pacientes com lesões recorrentes e respostas limitadas aos tratamentos clássicos, que apresentaram melhora clínica importante e alívio sintomático após terapia com laser de CO2 fracionado.

The Hailey-Hailey disease or familial benign pemphigus is a rare condition, characterized by vesicular lesions and erosions with a predilection for intertriginous areas associated with pain and burning sensation that affect the quality of life of patients. There are many topical and systemic treatments for the injuries that can temporarily promote partial or complete remission, but there is no curative treatment. Some treatment options with lasting results include dermabrasion and Erbium laser resurfacing (YAG or CO2). We report three cases of patients with recurrent lesions and limited responses to classical treatments, which showed significant clinical improvement after fractional CO2 laser therapy.

RESUMO

Ocronose exógena é doença cutânea rara, geralmente associada ao uso tópico de hidroquinona. Leva à hiperpigmentação acinzentada ou preto-azulada, devido à deposição dérmica de pigmento ocre. Não existe tratamento padronizado, e as opções terapêuticas são em geral frustrantes. Relatamos o caso de uma paciente com ocronose exógena após uso de hidroquinona, tratada com laser fracionado de CO2 e apresentando resultado bastante satisfatório.

Exogenous Ochronosis is a rare skin disease. It is usually associated with the topical use of hydroquinone, resulting in a grayish or bluish black hyperpigmentation due to dermal deposition of ocher pigment. There is no gold standard treatment and the therapeutic options are generally not effective. We report a case of a patient with exogenous achronosis after use of Hydroquinone, treated with CO2 Laser and showing very good results.

RESUMO

Abstract Porokeratosis is a disorder of epidermal keratinization characterized by the presence of annular hyperkeratotic plaques. Its etiopathogenesis is not yet fully understood, but a relationship with immunosuppression has been reported. Dermoscopic examination revealed a classic yellowish-white ring-like structure that resembled “volcanic crater contour” – the so-called cornoid lamella. We describe a case of porokeratosis in a female patient with chronic lymphedema, which was similar to Bowen’s disease due to the many glomerular vessels seen on clinical examination and dermoscopy.

RESUMO

O tratamento da foliculite decalvante representa grande desafio, com inúmeras recidivas e manutenção da atividade da doença por longo período. A remoção de pelo com laser vem sendo utilizada no manejo de desordens foliculares cicatriciais. Este relato tem por objetivoilustrar o caso de paciente portador de foliculite decalvante em membro inferior que realizou cinco sessões terapêuticas com laser neodímio:YAG (Nd:YAG) e assim obteve remissão completa das lesões inflamatórias.

Treatment of folliculitis decalvans is a major challenge, with a great number of recurrences and required maintenance of disease activity over a long period. Laser-based hair removal has been used in the management of scarring follicular disorders. The present case report aims to illustrate the case of a patient bearing folliculitis decalvans in the lower limb who underwent five therapeutic sessions of neodymium:YAG laser (Nd:YAG), achieving complete remission of the inflammatory lesions with the treatment.

RESUMO

Os grânulos de Fordyce são referidos como glândulas sebáceas ectópicas benignas caracterizadas por múltiplas pápulas amareladas, principalmente em lábio superior e observadas na maioria dos casos em homens adultos. Descrevem-se dois casos de pacientes com grânulos de Fordyce que foram submetidos ao tratamento com laser de CO2 obtendo bom resultado cosmético.

Fordyce granules are referred to as benign ectopic sebaceous glands characterized by multiple yellow papules, occurring mainly in the lower lip. It is mainly observed in adult men. The present study describes two cases of patients with Fordyce granules who were treated using a CO2 laser and obtained good cosmetic results.

RESUMO

BACKGROUND: Progressive macular hypomelanosis (PMH) is a dermatosis of unknown etiology. It has been concluded that it involves the presence of Propionibacterium acnes, a saprophyte of the pilosebaceous follicles. In our study, we investigated the presence of P. acnes in lesional and non-lesional skin of patients with PMH through quantitative real-time polymerase chain reaction (PCR) and bacterial culture from a skin fragment. MATERIALS AND METHODS: An observational, exploratory study, with laboratory comparison of lesional (study group) and non-lesional skin (comparison group), in patients with PMH, was carried out with 36 patients, seen in the dermatology outpatient setting at the Oswaldo Cruz University Hospital (OCUH), Recife, Pernambuco, Brazil, between March and May 2008. All patients were submitted to a Wood's lamp examination, mycological research, and biopsies of lesional and non-lesional skin from the back. Skin fragments were submitted to a histopathology test, bacterial culture, and a quantitative real-time PCR test. The program Statistical Package for Social Sciences, version 12.0, was employed for relationship analysis with the Wilcoxon and McNemar tests. RESULTS: There was a significant predominance of P. acnes on lesional skin, in comparison to non-lesional skin (P<0.001), as demonstrated by culture and quantitative real-time PCR. CONCLUSION: Although P. acnes is a saprophyte, the hypothesis may be raised that this microorganism participates in the development of PMH.

RESUMO

Hydroxyurea is an hydroxylated urea derivative used in many myeloproliferative disorders. Many, but unusual cutaneous disorders are related after its prolonged use. Their pathogenesis is not clear, but it is suggested that there is direct toxicity of the drug on the skin. We described a white, 75-year old man with diagnosis of Polycythemia Vera that in 11 years of treatment developed many cutaneous lesions: skin hyperpigmentation, atrophic lesions on forearms, longitudinal melanonychia of 20 nails, right forearm ulcer, cutaneous xerosis, ichthyosis and auricular spinocellular carcinoma. At this moment, the literature reports describe little diversity of lesions in affected patients.

RESUMO

Progressive macular hypomelanosis is a dermatosis of uncertain etiology. The participation of Propionibacterium acnes has been suggested in view of the response achieved following therapy with drugs that are active against this bacterium. This report describes a series of thirteen patients with progressive macular hypomelanosis who were treated with an association of lymecycline and benzoyl peroxide over a three-month period. Response to treatment was excellent and the positive results were maintained during the entire follow up period.

RESUMO

A hidroxiureia é um derivado hidroxilado da ureia utilizado em diversas desordens hematológicas. Inúmeras alterações cutâneas, porém raras, são relatadas após seu uso prolongado. A patogênese das mesmas não está bem esclarecida, porém, sugere-se que a droga tenha uma ação tóxica direta sobre a pele. Descrevemos um homem de 75 anos, branco, com diagnóstico de Policitemia Vera que, ao longo de 11 anos de tratamento com hidroxiureia, evoluiu com várias lesões cutâneas: hiperpigmentação da pele, lesões atróficas em antebraços, melanoníquia longitudinal das 20 unhas, úlcera em antebraço direito, xerose cutânea, ictiose em pernas e carcinoma espinocelular no pavilhão auricular direito. Até o momento, os relatos na literatura descrevem pouca diversidade de lesões nos pacientes acometidos.
