- Avaliação e tratamento do doente com acne – Parte I: Epidemiologia, etiopatogenia, clínica, classificação, impacto psicossocial, mitos e realidades, diagnóstico diferencial e estudos complementaresPublication . Figueiredo, A; Massa, A; Picoto, A; Soares, AP; Sousa-Basto, A; Lopes, C; Resende, C; Rebelo, C; Brandão, FM; Marques-Pinto, G; Schonenberger de Oliveira, H; Selores, M; Gonçalo, M; Bello, MTO Portuguese Acne Advisory Board (PAAB), grupo de dermatologistas portugueses que, à semelhança de grupos congéneres internacionais, tem dedicado particular atenção à definição de linhas de orientação para o tratamento da acne, pretende que o presente documento constitua uma ferramenta útil na abordagem dos doentes com esta patologia. Elaborou-se um dossier, para educação médica contínua, subdividido em 2 partes: Parte I – etiopatogenia e clínica; Parte II – abordagem terapêutica. Nesta Parte I, revêem-se os principais aspectos da clínica e da fisiopatogenia da acne à luz dos conhecimentos actuais. Discute-se a importância do impacto psicológico e social desta entidade e analisam-se os principais mitos e realidades com ela relacionados. Descrevem-se, sucintamente, as patologias mais relevantes no diagnóstico diferencial das lesões de acne. Enumeram-se as indicações para estudo hormonal, bem como os exames a efectuar nos doentes com esta patologia. The Portuguese Acne Advisory Board (PAAB), a group of Portuguese dermatologists with a special interest in acne, develop, as other international groups in this field, consensus recommendations for the treatment of acne. Overall, the goal is to provide a practice guideline to all physicians dealing with this entity. The continuing medical education dossier was divided in two parts: Part I – etiopathogeny and clinical features; Part II – therapy. This Part I reviews acne pathophysiology, clinical aspects, psychological and social impact and several myths surrounding this disease. Some other entities relevant for the differential diagnosis are described. The need of hormonal evaluation is also discussed
- Avaliação e tratamento do doente com acne - Parte II: tratamento tópico, sistémico e cirúrgico, tratamento da acne na grávida, algoritmo terapêuticoPublication . Figueiredo, A; Massa, A; Picoto, A; Soares, AP; Lopes, C; Resende, C; Rebelo, C; Brandão, FM; Marques-Pinto, G; Schonenberger de Oliveira, H; Selores, M; Gonçalo, M; Bello, RTO Portuguese Acne Advisory Board (PAAB), grupo de dermatologistas portugueses que, à semelhança de grupos congéneres internacionais, tem dedicado particular atenção à definição de linhas de orientação para o tratamento da acne, pretende que o presente documento constitua uma ferramenta útil na abordagem dos doentes com esta patologia. Elaborou-se um dossier, para educação médica contínua, subdividido em 2 partes: Parte I – etiopatogenia e clínica; Parte II – abordagem terapêutica. Nesta Parte II discute-se a abordagem terapêutica – tópica e sistémica – em cada forma clínica de acne, dando particular ênfase aos retinóides e aos antimicrobianos, e salientam-se as estratégias a adoptar para limitar a crescente resistência bacteriana aos antibióticos. Referem-se as indicações específicas para terapêutica hormonal e analisam-se as particularidades do tratamento da acne na grávida e lactante. Descrevem-se algumas técnicas para correcção das cicatrizes da acne. Por último, publica-se um algoritmo que pretende ilustrar a classificação da acne e definir, para cada tipo clínico, a abordagem terapêutica consensualmente recomendada. The Portuguese Acne Advisory Board (PAAB), a group of Portuguese dermatologists with a special interest in acne, develop, as other international groups in this field, consensus recommendations for the treatment of acne. Overall, the goal is to provide a practice guideline to all physicians dealing with this entity. The continuing medical education dossier was divided in two parts: Part I – etiopathogeny and clinical features; Part II – therapy. This Part II reviews the therapeutic approach of acne patients, including topical and oral medications, according to the clinical acne type. Retinoids and antimicrobial agents are discussed and strategies for limiting antibiotic resistance are provided. Appropriate patient selection for hormonal therapy and treatment of acne during pregnancy are also discussed. A variety of surgical techniques useful in the management of acne scars are referred. Finally, the recommendations outlined in the treatment algorithm reflect a consensus approach that takes into account the severity and the specific clinical subtypes of acne.
- Bleomycin-induced flagellate hyperpigmentationPublication . Resende, C; Araújo, C; Gomes, J; Brito, CBleomycin is a chemotherapeutic agent used in the treatment of different tumours. It has several side effects, including flagellate hyperpigmentation, which is a unique and a well-documented side effect of bleomycin therapy. We report a case of a 23-year-old woman with a personal history of ovarian dysgerminoma, who developed flagellate hyperpigmentation on trunk after bleomycin therapy.
- Late onset Ito's nevusPublication . Resende, C; Araújo, C; Vieira, AP; Brito, CDermal melanocytoses include a variety of congenital and acquired melanocytic lesions characterised by the presence of multiple spindle-shaped dendritic melanocytes in the dermis. These lesions are commonly found in the skin of Asians, but they can also appear in Caucasians. The Mongolian spot, nevi of Ota and Ito are the most common morphological forms. We report a case of a 24-year-old Caucasian woman presented with a 10-months history of progressive darkening of the right side of her upper back. Cutaneous examination revealed a macular blue-grey hyperpigmentation of the right side of her upper back. Biopsy specimen from the macule showed multiple darkly pigmented, spindle-shaped dendritic melanocytes in the superficial dermis, interstitially arranged between collagen bundles. The diagnosis of nevus of Ito was established. Our patient is maintaining vigilance in dermatology consultation.
- Rapidly lethal dermatomyositis associated with cutaneous lymphangitis carcinomatosaPublication . Resende, C; Araújo, C; Duarte, ML; Brito, CA 70-year-old woman with a recent diagnosis of dermatomyositis (DM) presented to the dermatology department for study of a probably paraneoplastic syndrome. On examination, we observed discrete, indurated, reddish, painful plaques and nodules on her abdomen and both thighs. A cutaneous biopsy from an abdominal nodule, performed as part of the paraneoplastic workup, was suggestive of cutaneous lymphangitis carcinomatosa, secondary to unknown malignancy. An extensive investigation to locate the site of the primary tumour revealed no specific findings. A course of palliative chemotherapy with cisplatin and 5-fluorouracil was then given, but the patient's condition deteriorated and 6 months after her initial observation the patient died. We describe this case because, to our knowledge, the association between DM and cutaneous lymphangitis carcinomatosa has not been described yet in the literature and to highlight that, DM can be a rapidly lethal disease.
- Schimmelpenning syndromePublication . Resende, C; Araújo, C; Vieira, AP; Ventura, F; Brito, CSchimmelpenning syndrome (SS) includes an organoid nevus that follows the lines of Blaschko and defects of brain, eyes, bones, or other systems. We report a case of a 3-month old female infant, who presented with several thin plaques, with irregular borders, yellowish color, which had a verrucous appearance, following the lines of Blaschko, mainly occupying the left side of posterior trunk, the left face, the right side of the anterior trunk, and the right upper limb. These plaques had been present since birth. In addition, she had a flat salmon to yellow nevus on the left parietal and temporal region of the scalp, with a bald patch. She was diagnosed after birth with an interauricular communication. The skin biopsy from the lesion of the right arm revealed an epidermal nevus that occupied the epidermis completely. Routine and other complementary laboratory blood tests, including platelet count, thyroid function tests, 25-hydroxy-vitamin D, parathyroid hormone, and plasma and urinary levels of calcium and phosphorus were negative. Cerebral magnetic resonance and renal ultrasound were normal. The diagnosis of SS was established. She is being followed in the clinics of Dermatology, Cardiology, Pediatrics, and Pediatric Neurology. We report this case to point out the importance of investigating patients with epidermal nevus to identify associated conditions.
