2. Occurrence of tayras (Eira barbara Linnaeus, 1758) with anomalous coloration in Cerrado remnants in the state of São Paulo, Brazil
Resumo: Colorações anômalas são desordens geralmente de origem genética, em que a pigmentação do corpo é reduzida (hipopigmentação) ou excessiva (melanismo), em partes ou totalmente. Casos de hipopigmentação já foram documentados em muitos mamíferos neotropicais, incluindo a irara (Eira barbara Linnaeus, 1758). Nós expandimos os relatos de oco

3. Notes on Vampyressa thyone (Chiroptera: Phyllostomidae): distribution, genetics and hypopigmentation
Abstract: The frugivorous bats of the genus Vampyressa include five neotropical species, and some of them are considered relatively rare and uncommonly encountered. The northernmost distribution of this genus is in Mexico where only one species, the monotypic Vampyressa thyone, is found. Here, we report the Northwesternmost record for this species, extending

4. Familial progressive hyper- and hypopigmentation: a report on a Chinese family and evidence for genetic heterogeneity
Abstract Background: Familial progressive hyper- and hypopigmentation (FPHH) is a rare genodermatosis that is characterized by diffuse hyper- and hypopigmented spots on the skin and mucous membranes. It is caused by a pathogenic mutation of the KITLG gene. Objectives: To investigate the clinical features and mutation of the KITLG gene in a Chinese family w

5. A novel frameshift mutation of Chediak-Higashi syndrome and treatment in the accelerated phase
Chediak-Higashi syndrome (CHS) is a rare autosomal recessive immunodeficiency disease characterized by frequent infections, hypopigmentation, progressive neurologic deterioration and hemophagocytic lymphohistiocytosis (HLH), known as the accelerated phase. There is little experience in the accelerated phase of CHS treatment worldwide. Here, we present a case

6. Efficacy and safety of superficial chemical peeling in treatment of active acne vulgaris
Abstract: Acne vulgaris is an extremely common condition affecting the pilosebaceous unit of the skin and characterized by presence of comedones, papules, pustules, nodules, cysts, which might result in permanent scars. Acne vulgaris commonly involve adolescents and young age groups. Active acne vulgaris is usually associated with several complications like

7. Tetrasomy 3q26.32-q29 due to a supernumerary marker chromosome in a child with pigmentary mosaicism of Ito
Abstract Pigmentary mosaicism of Ito (PMI) is a skin abnormality often characterized by hypopigmentation of skin, following, in most cases, the Blaschko lines, usually associated with extracutaneous abnormalities, especially abnormalities of the central nervous system (CNS). It is suggested that this pattern arises from the presence and migration of two cell

8. Vulvar vitiligo-like depigmentation and multiple halos of hypomelanosis at the trunk following treatment with imiquimod 5% cream for vulvar condylomata: casual or related events?
A 25-year-old Caucasian female with multiple genital warts involving the vulvar area was treated with imiquimod 5% cream. During follow-up the patient developed areas of hypopigmentation at the site of application of imiquimod cream and areas of hypomelanosis around multiple preexisting nevi of the trunk. At 18 months follow-up genital depigmentation persist

9. A prospective, open, comparative study of 5% potassium hydroxide solution versus cryotherapy in the treatment of genital warts in men
BACKGROUND: Genital warts are caused by human papillomavirus infection and represent one of the most common sexually transmitted diseases. Many infections are transient but the virus may recur, persist, or become latent. To date, there is no effective antiviral treatment to eliminate HPV infection and most therapies are aimed at the destruction of visible l

10. Investigação citogenética em indivíduos com mosaico pigmentar do tipo Ito / Cytogenetic analysis in individuals with mosaic pigmentary of Ito type
O Mosaico pigmentar tipo Ito é uma alteração cutânea frequente, caracterizada por hipopigmentação da pele que, na maioria dos casos, segue o padrão linhas de Blaschko, geralmente associada a anomalias extracutâneas, sobretudo anomalias do Sistema Nervoso Central (SNC). Sugere-se que esse padrão decorre da presença e migração de duas linhagens cel

11. Avaliação da presença do Propionibacterium acnes em pele lesional e não lesional de pacientes com hipomelanose macular progressiva por cultura e PCR em tempo real
Introdução: A hipomelanose macular progressiva é uma dermatose caracterizada por máculas hipocrômicas localizadas principalmente em tronco, que tendem a confluir na linha média. Em pacientes melanodérmicos, as lesões contrastam com a pele normal prejudicando a auto-estima dos pacientes. Sua etiologia permanece especulativa, sendo sugerida a participa

12. An oculocerebral hypopigmentation syndrome: a case report with clinical, histochemical, and ultrastructural findings.
A 4 year old boy is reported with tyrosinase positive hypopigmentation, mental retardation, ataxia, and myopia. Radiological investigation showed occipital cerebral atrophy, coxa valga, and generalised osteoporosis. The skin histology and electron microscopy are reported and discussed. The clinical features are similar to those of the oculocerebral hypopigme
