Síndrome de Stewart-Treves no membro inferior com apresentação exuberante: relato de caso / Profuse Stewart-Treves syndrome in the right leg: a case report

A Síndrome de Stewart-Treves é uma rara condição onde um angiossarcoma se desenvolve sobre área de linfedema crônico. Afeta mais frequentemente os membros superiores e representa 5% dos casos de angiossarcoma. Apesar de ser mais comum em mulheres submetidas a mastectomia radical e esvaziamento axilar por neoplasia de mama, pode ocorrer a partir de linfedema de outras etiologias. Clinicamente as lesões são caracterizadas por nódulos únicos ou múltiplos de cor avermelhada ou azulada no estágio inicial e, em estágio avançado, podem evoluir para massas hemorrágicas e até gangrena. O prognóstico é ruim e a conduta cirúrgica com excisão ampla ou amputação oferecem uma maior chance de sobrevida. Relata-se um caso de Síndrome de Stewart-Treves na perna direita, apresentando-se de forma exuberante e com acometimento de linfonodos pélvicos e abdominais.

Stewart-Treves syndrome is a rare condition characterized by the development of an angiosarcoma at sites of chronic lymphedema. It most often affects the upper limbs and accounts for 5% of cases of angiosarcoma. Although the syndrome is more common in women undergoing radical mastectomy and axillary dissection for breast cancer, it may result from lymphedema of other etiologies. Clinically, the lesions are characterized by single or multiple bluish-red nodules in the early stage and may progress to hemorrhagic masses and even gangrene in advanced stages. The prognosis is poor, and surgical management with wide excision or amputation offers a greater chance of survival. We report a case of profuse Stewart-Treves syndrome in the right leg, with involvement of pelvic and abdominal lymph nodes.

Prevalence and characterization of neonatal skin disorders in the first 72 h of life / Prevalência e caracterização das afecções cutâneas neonatais nas primeiras 72 horas de vida

Abstract Objective: To determine the prevalence of neonatal dermatological findings and analyze whether there is an association between these findings and neonatal and pregnancy characteristics and seasonality. Methods: Newborns from three maternity hospitals in a Brazilian capital city were randomly selected to undergo dermatological assessment by dermatologists. Results: 2938 neonates aged up to three days of life were randomly selected, of whom 309 were excluded due to Intensive Care Unit admission. Of the 2530 assessed neonates, 49.6% were Caucasians, 50.5% were males, 57.6% were born by vaginal delivery, and 92.5% of the mothers received prenatal care. Some dermatological finding was observed in 95.8% of neonates; of these, 88.6% had transient neonatal skin conditions, 42.6% had congenital birthmarks, 26.8% had some benign neonatal pustulosis, 2% had lesions secondary to trauma (including scratches), 0.5% had skin malformations, and 0.1% had an infectious disease. The most prevalent dermatological findings were: lanugo, which was observed in 38.9% of the newborns, sebaceous hyperplasia (35%), dermal melanocytosis (24.61%), skin desquamation (23.3%), erythema toxicum neonatorum (23%), salmon patch (20.4%), skin erythema (19%), genital hyperpigmentation (18.4%), eyelid edema (17.4%), milia (17.3%), genital hypertrophy (12%), and skin xerosis (10.9%). Conclusions: Dermatological findings are frequent during the first days of life and some of them characterize the newborn's skin. Mixed-race newborns and those whose mothers had some gestational risk factor had more dermatological findings. The gestational age, newborn's ethnicity, gender, Apgar at the first and fifth minutes of life, type of delivery, and seasonality influenced the presence of specific neonatal dermatological findings.

Resumo Objetivo: Verificar a prevalência dos achados dermatológicos nos primeiros dias de vida e analisar se há associação com características neonatais, gestacionais e sazonalidade. Métodos: Recém-nascidos de três maternidades de uma capital brasileira foram selecionados aleatoriamente para serem submetidos ao exame dermatológico feito por dermatologistas. Resultados: Foram selecionados aleatoriamente 2.839 neonatos com até 72 horas de vida, 309 foram excluídos por terem sido admitidos em Unidade de Tratamento Intensivo. Dos 2.530 neonatos examinados, 49,6% eram da etnia branca e 50,5% do sexo masculino. Foi observado algum achado dermatológico em 95,8% dos recém-nascidos; desses, 88,6% tinham lesões cutâneas transitórias neonatais, 42,6% marca de nascimento, 26,8% pustulose benigna neonatal, 2% lesões secundárias ao trauma, 0,5% malformação cutânea e 0,1% doença infecciosa. O achado dermatológico mais frequente foi o lanugo, observado em 38,9% dos neonatos, seguido por hiperplasia de glândulas sebáceas (35%), melanocitose dérmica (24,6%), descamação da pele (23,3%), eritema tóxico neonatal (23%), mancha salmão (20,4%), eritema da pele (19%), hiperpigmentação da genitália (18,4%), edema palpebral (17,4%), cistos de mília (17,3%), hipertrofia da genitália (12%) e xerose cutânea (10,9%). Conclusões: Os achados dermatológicos são frequentemente identificados nos primeiros dias de vida e muitos deles caracterizam a pele do recém-nascido. Os neonatos pardos e aqueles cujas mães apresentavam algum fator de risco gestacional tiveram mais achados dermatológicos. A idade gestacional, a etnia do neonato, o gênero, o índice de Ápgar, o tipo de parto e a sazonalidade influenciaram na presença de manifestações cutâneas específicas.

Benign skin disease with pustules in the newborn

Abstract: The neonatal period comprises the first four weeks of life. It is a period of adaptation where the skin often presents several changes: transient lesions, resulting from a physiological response, others as a consequence of transient diseases and some as markers of severe disorders. The presence of pustules in the skin of the newborn is always a reason for the family and for the assisting doctor to be worried, since the newborn is especially vulnerable to bacterial, viral or fungal infection. However, the majority of neonatal skin pustules is not infectious, comprising the benign neonatal pustulosis. Benign neonatal pustuloses are a group of clinical disease characterized by pustular eruptions in which a contagious agent is not responsible for its etiology. The most common ones are erythema toxicum neonatorum, the transient neonatal pustular melanosis and the benign cephalic pustulosis. These dermatoses are usually benign, asymptomatic and self-limited. It is important that the dermatologist and the neonatologist can identify benign and transient lesions, those caused by genodermatoses, and especially differentiate between neonates with systemic involvement from those with benign skin lesions, avoiding unnecessary diagnostic tests and worries.

The use of ustekinumab in a patient with severe psoriasis and positive HBV serology

Psoriasis is a chronic inflammatory, immune-mediated disease that affects 1% to 2% of the world's population. Immunobiological medications are prescribed for certain patients with severe forms of psoriasis, however, these drugs increase the risk of reactivation of viral diseases such as hepatitis B. We report the case of a patient with severe psoriasis with positive serology for the Hepatitis B virus, who received ustekinumab (a human monoclonal antibody against interleukin 12 and 23). In this patient, the use of ustekinumab did not reactivate the Hepatitis B virus. Given the high prevalence of chronic viral infections in patients who are candidates for biologic therapy, as well as the potential for reactivate chronic viral illness, randomized controlled studies are needed to assess the risks and benefits of such therapy in these populations.
