- Apresentação Curiosa de um Tumor Cutâneo e o seu Sucesso TerapêuticoPublication . Santos, G; Sousa, L; João, AA doença de Bowen é um carcinoma espinocelular (CEC) in situ que pode evoluir para carcinoma espinocelular invasivo. Mulher, 61 anos, referia placa rosada, anular, bem delimitada, não descamativa, na região pré-auricular direita com 2 anos de evolução. Desde 2 meses antes da consulta, surgiu no seu centro um nódulo translúcido, com telangiectasias. A biopsia excisional do nódulo mostrou carcinoma espinocelular com doença de Bowen na periferia. A placa remanescente foi tratada com laser de CO2 seguida de terapêutica fotodinâmica com desaparecimento completo da lesão. Salienta-se este caso pela curiosidade da sua apresentação clínica e pelos bons resultados terapêutico e estético.
- Do You Know This Syndrome?Publication . Santos, G; Lestre, S; João, APOEMS syndrome is a unique clinical entity, the diagnosis of which is made when polyneuropathy and monoclonal gammopathy occur together, associated with other changes such as organomegaly, endocrinopathy, skin changes and papilledema. Cutaneous manifestations are heterogeneous, with diffuse cutaneous hyperpigmentation, hemangiomas and hypertrichosis occurring more frequently. We report the case of a 65- year-old female patient with this syndrome, diagnosed after 15 years of disabling peripheral neuropathy.
- Exacerbation of Recalcitrant Cutaneous Sarcoidosis with Adalimumab - a Paradoxical Effect? A Case ReportPublication . Santos, G; Sousa, L; João, AThe paradoxical adverse effects of tumor necrosis factor-alpha (TNF-alpha) antagonists have been described frequently as a result of the widespread use of these drugs. Among the TNF-alpha blocking agents, few reports exist relating the use of adalimumab in cutaneous sarcoidosis, although all of them show good results. More recently, sarcoidosis onsets have been reported with various TNF-alpha inhibitors. The current case is, to our knowledge, the first to describe the exacerbation of cutaneous lesions of sarcoidosis treated with adalimumab.
- Intravenous Immunoglobulin for the Treatment of Quetiapin-Induced Bullous Pemphigoid in an HIV-Infected PatientPublication . Cabete, J; Santos, G; Páris, F; Serrão, V; Fidalgo, AThe authors present the case of a 48-year-old woman with HIV-associated dementia treated with antiretroviral therapy and psychoactive drugs, to whom bullous pemphigoid(BP) was diagnosed. Given incomplete response to corticotherapy, and azathioprine-induced bicytopenia,intravenous immunoglobulin(IVIG) was initiated. Despite transient disease control, recurrent flares suggested a persistent triggering factor. Specifically, quetiapin was implicated and discontinued with an immediate clinical response. Inadvertent re-challenge with olanzapine(a related drug)led to a new eruption, confirming drug-induced BP (DIBP). A total of six IVIG cycles were completed, without severe side effects to report, namely HIV disease progression. HIV-related autoimmune bullous diseases are rare. Treatment of severe drug eruptions is primarily based on immunossupressive drugs, raising concerns regarding additional immunossupression. This case suggests IVIG as a valuable option for the treatment of BP in HIV patients. In addition, quetiapin should be added to the list of neuroleptics previously linked to DIBP.
- Larva Migrans Cutânea - a Propósito de um Caso TípicoPublication . Santos, G; João, AA larva migrans cutânea é frequente em regiões tropicais e sub-tropicais e é causada pela migração de larvas de nemátodos na pele. O diagnóstico é efectuado essencialmente pelas características epidemiológicas da dermatose e pela sua semiologia clínica. Geralmente o tratamento é bem sucedido com albendazol ou ivermectina. Descreve-se o caso clínico de uma mulher de 54 anos que regressou de férias na Jamaica há cerca de 15 dias. A doente iniciou no local, uma pápula eritematosa, bem delimitada, com 2mm de largura no bordo externo do pé esquerdo, progredindo em trajecto serpiginoso pela planta até atingir o bordo interno do pé. Negava febre ou outros sintomas associados. Clinicamente a dermatose era muito sugestiva de larva migrans cutânea pelo que se institui terapêutica com albendazol. O presente caso serve para relembrar uma dermatose pouco frequente em Portugal. Pretende-se também alertar para o reconhecimento precoce desta dermatose, que apesar de autolimitada é motivo de grande ansiedade para os doentes.
- Leg Ulcers in Antiphospholipid Syndrome Secondary to Systemic Lupus Erythematosus Treated with Intravenous ImmunoglobulinPublication . Santos, G; João, A; Sousa, LBACKGROUND: Despite encouraging reports on the efficacy of intravenous immunoglobulin (IVIg) in antiphospholipid syndrome, the clinical value of this treatment is not well established, and most of the data are based on case reports and small series of patients. OBSERVATION: We describe the significant improvement of leg ulcers with IVIg in a 61-year-old female, with diabetes mellitus, venous peripherical insufficiency and secondary antiphospholipid syndrome to systemic lupus erythematosus. CONCLUSIONS: This case illustrates a rare cause of leg ulcers and documents that IVIg may be an effective adjuvant treatment in the management of selected patients with antiphospholipid syndrome when conventional strategies using subcutaneous heparin and low-dose aspirin are insufficient.
- A Nonhealing Ulcer on the Nose. A Case ReportPublication . Santos, G; João, ADermatitis artefacta is a disease characterized by self-inflicted skin lesions as the result or manifestation of psychiatric disorders or specific stress situations. Clinical manifestations range from superficial erosions to deep wounds. Because of its rarity and the polymorphism of the lesions, dermatitis artefacta is often a challenge for the clinicians. This report presents the case of a 62-year-old woman who had an ulcer of the nose lasting for three years caused by digital manipulation. Early recognition of dermatitis artefacta is difficult but avoids unnecessary treatments. A multidisciplinary approach to this entity is necessary to obtain the best results.
- Reconstrução Complexa de Defeito do Terço Inferior do NarizPublication . Santos, G; Goulão, JA reconstrução de defeitos nasais deve preservar a integridade das funções e expressões faciais. A localização do tumor, o tamanho, as camadas atingidas e a disponibilidade de tecido dador devem ser considerados, de modo a estabelecer o procedimento cirúrgico adequado. Em qualquer reconstrução nasal, é necessário ter em conta três camadas: revestimento interno, suporte cartilagíneo e revestimento externo. Os autores descrevem a reconstrução de um defeito de espessura total do terço inferior do nariz após excisão de carcinoma basocelular recidivado, com retalho septal mucoso ipsilateral para a reconstrução do revestimento interno, enxerto livre de cartilagem auricular para o suporte cartilagíneo e retalho de transposição nasogeniano para o revestimento externo, num único tempo cirúrgico e com resultado estético e funcional final aceitável.
- Scalp Porocarcinoma: a Rare DiagnosisPublication . Brasileiro, A; Santos, G; Fidalgo, A; João, AAdnexal skin tumours are rare conditions, and often clinically indistinguishable from other cutaneous neoplasms. Porocarcinoma, a sweat gland malignant tumour, is more commonly found on extremities. Few reports in other anatomic locations can be found in the literature, and those arising on the scalp are even scarcer. The authors report the case of an 84-year-old diabetic man, with a tumour on the left parietal region for 1 year, which histopathological features were consistent with porocarcinoma. The importance of histopathologic diagnosis is hereby emphasized by the more aggressive behaviour of this tumour, therefore requiring clinical actuation accordingly.
- Syndrome In QuestionPublication . Santos, G; Sousa, LMultiple autoimmune syndrome is a rare condition, described by Humbert and Dupond in 1988. It is defined by the association of at least 3 autoimmune diseases in the same patient. Vitiligo is the most common skin condition in this syndrome. This article presents the case of a 31-year-old male with vitiligo, alopecia areata, Crohn's disease, psoriasis vulgaris and oral lichen planus. The rarity of this case is highlighted by the coexistence of four autoimmune skin diseases in association with Crohn's disease, never described in the literature.
