Granulomatous slack skin T-cell lymphoma: an important differential diagnosis with giant cell tumor of soft tissue

Abstract: Granulomatous slack skin is an indolent T-cell lymphoma, considered to be a variant of mycosis fungoides. Clinically it is characterized by areas of redundant skin, wrinkled, inelastic, with variable erythema and infiltration besides a poikilodermic surface. A differential diagnosis unknown to most dermatologists is the giant cell tumor of soft tissue, which is an extremely rare low-grade sarcoma. The authors report a patient who had undergone extensive surgery because of a primary diagnosis of giant cell tumor of soft tissue, but which proved to be granulomatous slack skin after a second interventional procedure with confirmatory histopathology.

The Shampoo pH can Affect the Hair: Myth or Reality?

AIM: Dermatologists most frequently prescribe shampoos for the treatment of hair shed and scalp disorders. Prescription of hair care products is often focused on improving scalp hair density, whereas the over-the-counter products focus on hair damage prevention. Little is taught in medical schools about the hair cosmetics, so that the prescriptions are based only on the treatment of the scalp and usually disregards the hair fiber health. MATERIALS AND METHODS: In this work, we review the current literature about the mode of action of a low-pH shampoo regarding the hair shaft's health and analyze the pH of 123 shampoos of international brands. RESULTS: All shampoo pH values ranged from 3.5 to 9.0. 38.21% of all 123 shampoos presented a pH ≤ 5.5 (IC: 29.9-47%) and 61.78% presented a pH > 5.5. 26 anti-dandruff shampoos were analyzed. About 19.23% presented pH ≤ 5.5.(IC: 7.4-37.6%). 80.77% of all anti-dandruffs shampoos presented a pH > 5.5. The dermatological shampoo group (n = 19) presented 42.10% with pH ≤ 5.5 (IC: 21.8-64.6%), and 57.90% with pH > 5.5. Among the commercial (popular) products (n = 96), 34.37% presented pH ≤ 5.5 (IC: 25.4-44.3%) and 65.62% presented pH > 5.5. 15 professional products (used in hair salons) were analyzed, of which 75% had a pH ≤ 5.5 (IC: 18-65, 4%), and 25% had a pH > 5.5. 100% of the children's shampoos presented a pH > 5.5. CONCLUSIONS: Alkaline pH may increase the negative electrical charge of the hair fiber surface and, therefore, increase friction between the fibers. This may lead to cuticle damage and fiber breakage. It is a reality and not a myth that lower pH of shampoos may cause less frizzing for generating less negative static electricity on the fiber surface. Interestingly, only 38% of the popular brand shampoos against 75% of the salons shampoos presented a pH ≤ 5.0. Pediatric shampoos had the pH of 7.0 because of the "no-tear" concept. There is no standardized value for the final pH. The authors believe that it is important to reveal the pH value on the shampoo label, but studies are needed to establish the best pH range for both the scalp and the hair fiber's health.

Shiitake dermatitis: the first case reported in Brazil.

Shiitake Dermatitis is often presented as papules and erythemato-violaceous linear streaks. It can be associated with bleomycin treatment, dermatomyositis and shiitake mushroom (Lentinus edodes). There is not any previous report concerning this rare etiology in our country. Shiitake is the second most consumed mushroom worldwide and it can cause flagellate erythema when ingested raw or half cooked. It has a higher incidence in Oriental countries because of their eating habits, this is the first case reported in Brazil, in a male patient that presented a cutaneous rash after consuming this raw mushroom.

A dermatite flagelada é caracterizada por pápulas eritematosas lineares com aspecto de "chicotada". A etiologia pode ser associada ao uso de bleomicina, dermatomiosite e shiitake (Lentinus edodes). Este é o segundo cogumelo mais consumido no mundo e pode ser causa de dermatite flagelada quando ingerido cru ou mal cozido. Não há relatos nas literaturas de quadro de dermatite flagelada por shiitake em nosso país, reportamos o primeiro caso no Brasil de um paciente masculino que desenvolveu o quadro após a ingesta desse cogumelo cru.

Pênfigo vegetante induzido por uso de enalapril / Pemphigus vegetans induced by use of enalapril

Pênfigo Vegetante foi primeiramente descrito como uma variante do pênfigo vulgar, em 1876, por Neumann. Em 1889, Hallopeau descreveu um paciente com pústulas e placas vegetantes, e sugeriu ser uma variante do Pênfigo Vegetante de Neumann. Ambos os tipos de pênfigo vegetante são caracterizados pelo desenvolvimento de placas vegetantes, especialmente, em dobras (axila, inguinal, perianal). Os autores apresentam e discutem um caso de Pênfigo Vegetante com uma clínica incomum, com ausência de acometimento de mucosas e áreas de flexão, em paciente idosa, associado ao uso de enalapril como possível desencadeador. Diagnóstico clínico e histológico sugestivos de Pênfigo Vegetante tipo Hallopeau.

Pemphigus Vegetans was first described as a variant of Pemphigus Vulgaris in 1876 by Neumann. In 1889, Hallopeau described a patient with pustules and vegetating plaques, suggesting that it would be a variant of Pemphigus Vegetans of Neumann. Both types of Pemphigus Vegetans are characterized by the development of vegetating plaques especially on skin folds (axillae, groin, perianal region). The authors present and discuss a case of Pemphigus Vegetans with an unusual clinical presentation lacking involvement of mucous membrane and flexor surfaces in an elderly female patient, associated with the use of enalapril as possible trigger factor. Clinical and histological diagnosis were suggestive of Pemphigus Vegetans of the Hallopeau type.

Congenital self healing reticulohistiocytosis in a newborn (Hashimoto Pritzker).

Congenital self-healing reticulohistiocytosis is the benign spectrum of Langerhans Cell Histiocytosis, characterized by cutaneous lesions at birth or in the neonatal period, absence of systemic manifestations and spontaneous resolution of clinical status. Despite the benign and often self-resolving course in most patients, studies show that in some cases there may be metastasis or recurrence of the disease, emphasizing that the clinical course is variable, requiring long-term follow-up. The monitoring of the patient for a long period is important to detect possible systemic involvement, as there is a report of recurrence involving the skin, mucosa, bone and pituitary gland.

Retículo-histiocitose congênita autolimitada em recém-nascido (Hashimoto- Pritzker) / Congenital self healing reticulohistiocytosis in a newborn (Hashimoto Pritzker)

A retículo-histiocitose congênita autolimitada é o espectro benigno das histiocitoses de células de Langerhans, caracterizada pela presença de lesões cutâneas ao nascimento ou no período neonatal, ausência de manifestações sistêmicas e resolução espontânea do quadro clínico. Apesar do curso benigno e frequente autorresolução na maior parte dos pacientes, estudos mostram que, em alguns casos, pode haver disseminação ou recaída da doença, enfatizando que o curso clínico é variável, havendo necessidade de seguimento em longo prazo. O acompanhamento do paciente por longo período é importante para detectar possível envolvimento sistêmico, pois existe relato de recorrência, envolvendo pele, mucosa, ossos e glândula pituitária.

Perfil dos diagnósticos de hospitalização de crianças até 5 anos no município de Blumenau-SC

Objetivo: apresentar o perfil dos diagnósticos de hospitalização de crianças até 5 anos, durante 2 anos no município de Blumenau-SC.Métodos: realizou-se uma revisão dos diagnósticos de internação das crianças menores de 5 anos que foram hospitalizadas nos 3 principais hospitais da cidade de Blumenau (Hospital Santo Antônio, Santa Isabel e Santa Catarina) num período de 2 anos, o que permitiu avaliar as causas de acordo com a sazonalidade. Resultados: os dados obtidos evidenciaram um número maior de internações em meninos e lactentes até 11 meses. Houve predomínio de internações no hospital referência materno-infantil do município. As estações do ano não tiveram grande repercussão nas hospitalizações, exceto o verão que teve um númeromenor. Os principais motivos de hospitalização encontrados foram as doenças do trato respiratório, seguida das do trato gastrointestinal e das causas externas. Conclusão: houve maior número de hospitalizaçõesem lactentes até 11 meses, do sexo masculino, por causas respiratórias. As causas gastrointestinais e externas também corresponderam a um grande número de internações. Não houve variação do total de hospitalizações quando levado em conta a variação das estações do ano.

Know the profile of hospitalization give us the knowledge from themain diseases that occur in children until 5 years old, helping us on the prevention, diagnostic and treatment of these pathologies .The objective of this project was to determine the profile of children?s hospitalization, in 2 years, in Blumenau - Santa Catarina- Brazil. A revision on the diagnostics of hospitalization was made in three hospitals of this town (Hospital Santo Antônio, Santa Isabel e Santa Catarina) during 2 years.The informations were arranged in graphics and tables. The results obtained were that boys were more hospitalized them girls just as the suckling until 11 months. There was a predominancyof hospitalizations in the hospital that is mother-child reference. The season didn?t make difference on the total cases, except for the summer that had a significant lower number. The principal diseases were respiratory followed by gastricintestinal) and external causes,like car accident, scald and drowning.
