The results suggest that the Brazilian-Portuguese version of the DLQI is a reliable and valid outcome measure to be used in LE clinical studies.
Because of its distinctive clinical features and histopathological characteristics, zosteriform connective tissue nevus is considered a separate entity from other connective tissue nevi. Only two cases have previously been reported in the worldwide dermatological literature. Here we report a zosteriform connective tissue nevus in a 3-year-old boy with similar clinical presentation.
We report the optical and ultrasonic biomicroscopy and confocal microscopy findings in bilateral stromal keratitis (keratoendotheliitis), a rare ocular manifestation of systemic lupus erythematosus (SLE). Examination revealed deposits with polyrefringent crystals. Topical corticosteroid produced regression of the corneal edema, but there was an increase in corneal opacity. Ultrasound biomicroscopy images confirmed the deep location of the corneal opacities, and confocal microscopy showed a disruption of the corneal stroma and crystal-like bodies.
Background The polymorphic clinical presentations of schistosomiasis and leishmaniasis allow their inclusion in the differential diagnoses of several conditions. Although an overlap in distribution of these diseases has been reported in endemic areas, coinfection with cutaneous schistosomiasis and cutaneous leishmaniasis in the same patient is rare. Objectives We report an unusual case of concomitant cutaneous schistosomiasis and cutaneous leishmaniasis. Actions for the management and diagnosis were proposed. Methods A patient presented with cutaneous lesions on the abdomen and left elbow. The presence of degenerated ova of Schistosoma mansoni in the skin biopsy led to perform a complementary investigation with immunohistochemical techniques, rectal biopsy and abdominal ultrasonography. After the left elbow lesions had failed to improve after several weeks of standard treatment, a new biopsy was performed and led to diagnosis of another infection. Results The patient lived in an endemic area for two infectious diseases (schistosomiasis and leishmaniasis). Biopsies revealed chronic granulomatous dermatitis. Degenerated S. mansoni eggs were found in the abdominal lesion and in a rectal biopsy specimen. Ultrasonography revealed hepatic involvement. Despite combination treatment with oxamniquine and praziquantel, a cutaneous lesion persisted on the left elbow; a new biopsy revealed amastigote forms of Leishmania. The patient was successfully treated with intramuscular and intralesional meglumine antimoniate. Conclusions The presence of a similar granulomatous infiltrate in lesions caused by the two different infectious agents led to a delay in the diagnosis of cutaneous leishmaniasis. This report serves as a warning of the unusual possibility of cutaneous schistosomiasis and leishmaniasis coinfection in an endemic area.
BACKGROUND -Capillaroscopy is an useful diagnostic tool that is non-invasive, reproducible, able to assess the capillaries in the periungal region and that assists in the differential diagnosis of connective tissue diseases. OBJETIVES -The aim of the study was to distinguish chronic cutaneous lupus erythematosus and systemic lupus erythematosus from controls assessed by nailfold capillaroscopy. METHODS -Seventy patients with lupus erythematosus (37 with chronic cutaneous lupus erythematosus and 33 with systemic lupus erythematosus) were studied by the technique of capillary microscopy and compared to 32 controls. RESULTS -The presence of ectatic (p=0.027; p=0.001), meandering (p=0.001; p=0.007), corkscrew capillaries (p=0.011; p=0.005) and nailfold bleeding (p=0.004; p=0.001) distinguished between the two groups of patients (chronic cutaneous lupus erythematosus and systemic lupus erythematosus) from controls. The variable meandering loops could be predictive for systemic lupus erythematosus (OR=8.308). The independent variables ectatic loops (OR=12.164) end nailfold bleedings (OR=5.652) were predictive for chronic cutaneous lupus erythematosus. CONCLUSIONSCapillaroscopy can help in the management of patients, since the presence of typical capillaroscopic abnormalities seems to be related to the development of lupus erythematosus. The independent predictive variables for systemic lupus erythematosus were meandering loops, and, for chronic cutaneous lupus erythematosus, ectasic loops and nailfold bleedings. Keywords: Capillaries; Lupus erythematosus, discoid; Lupus erythematosus, systemic; Microscopic angioscopy (p=0,027; p=0,001), enovelados (p=0,001; p=0,007) e em saca-rolhas (p=0,011;p=0,005), além de hemorragias capilares (p=0,004; p=0,001) Resumo: FUNDAMENTOS -A capilaroscopia é método não invasivo e reprodutível capaz de analisar diretamente os capilares na região periungueal, auxiliando no diagnóstico diferencial das doenças do tecido conectivo. OBJETIVOS -Estudar, por meio da capilaroscopia periungueal, pacientes com lúpus eritematoso cutâneo crôni-co, lúpus eritematoso sistêmico e grupo controle. MÉTODOS -Foram analisados 70 pacientes pela capilaroscopia periungueal, sendo 37 com lúpus eritematoso cutâneo crônico e 33 com forma sistêmica, comparados a 32 indivíduos sadios. RESULTADOS -A presença de capilares ectasiados
