Oral findings in secondary syphilis

Background: Syphilis is a sexually transmitted disease caused by Treponema pallidum. However, there are of hematogenic and vertical transmission. All health care professionals must be aware of the manifestations of this condition, such as oral lesions. Objectives: This study to analyze and compare four clinical cases of syphilis that were diagnosed based on lesions in the oral cavity with published literature. Material and Methods: Four patients with a confirmed sorologic and clinical diagnosis of syphilis were examined, confirmated from manifestation of oral lesions together with analysis of serological laboratory tests and histopathological analyses. Results: Lesions were found in classic sites such as lips, tongue and skin. However, there were also lesions on the hard palate, and labial commissure, which correspond to less than 5% of the syphilis oral manifestations. Conclusions: The practice of unprotected oral sex may result in infection and development of syphilis. The acknowledgment of the oral manifestations of syphilis in all its period of training for health professionals is of basic importance, the association of clinical features, histopathological findings and serological tests are required to complete the diagnosis and correct treatment (AU)

Pseudotumoral presentation of chronic pulmonary schistosomiasis without pulmonary hypertension.

Schistosomiasis is a disease that, in Brazil, is caused by Schistosoma mansoni and is transmitted by snails of the genus Biomphalaria. This species occurs in Africa, the Antilles and South America. The parasite, developing to the adult stage in the vascular system of the host, migrates to the mesenteric veins. Each female lays approximately 400 eggs per day, and these travel from the submucosa to the intestinal lumen. There have been reported cases in which S. mansoni eggs were identified in the lungs of patients with no evidence of liver fibrosis. We report a case with this atypical presentation of the disease. The patient presented nonpleuritic chest pain, significant weight loss and dry cough. A CT scan revealed an irregular tumor in the left lower lobe. However, a lung biopsy revealed non-viable S. mansoni eggs. The patient presented no clinical signs of pulmonary or portal hypertension; nor was either identified through diagnostic tests.

Forma pseudoneoplásica de esquistossomose pulmonar crônica sem hipertensão pulmonar / Pseudotumoral presentation of chronic pulmonary schistosomiasis without pulmonary hypertension

A esquistossomose é uma doença que, no Brasil, é causada pelo Schistosoma mansoni e transmitida através da água por moluscos do gênero Biomphalaria. Essa espécie ocorre na África, nas Antilhas e na América do Sul. O parasita, ao atingir a fase adulta de seu ciclo biológico no sistema vascular do homem, alcança as veias mesentéricas. Cada fêmea põe cerca de 400 ovos por dia, e estes, a partir da submucosa, chegam à luz intestinal. Há relatos de casos a respeito de ovos de S. mansoni nos pulmões de pacientes sem evidência de fibrose hepática. Relatamos um caso dessa forma atípica de apresentação da doença. O paciente apresentava dor torácica não-ventilatóriodependente, perda ponderal significativa e tosse seca. A TC de tórax mostrou uma tumoração irregular no lobo inferior esquerdo, mas somente a biópsia pulmonar evidenciou ovos de S. mansoni degenerados. O paciente não apresentava sinais clínicos de hipertensão pulmonar ou portal, as quais tampouco foram diagnosticadas através de exames.

Criptococose pulmonar isolada em paciente imunocompetente / Isolated pulmonary cryptococcosis in an immunocompetent patient

O presente trabalho relata um caso de criptococose pulmonar isolada em paciente com sintomas respiratórios, sem imunossupressão e sorologia negativa para o vírus da imunodeficiência humana, com massa pulmonar no radiograma de tórax. O diagnóstico foi confirmado pela biópsia transbrônquica e lavado broncoalveolar. A paciente recebeu tratamento ambulatorial com fluconazol, na dose de 300 mg/dia por seis meses, evoluindo com melhora clínica e regressão parcial da imagem radiológica. O presente caso ilustra uma apresentação não freqüente da criptococose pulmonar e faz considerações sobre a abordagem terapêutica com base na literatura.

In this study, we report a case of pulmonary cryptococcosis in a patient presenting respiratory symptoms and a lung mass on the chest X-ray. The patient had no concomitant diseases, was seronegative for human immunodeficiency virus and was not receiving immunosuppressive therapy of any kind. The diagnosis was confirmed through transbronchial biopsy and bronchoalveolar lavage. The patient was treated as an outpatient with fluconazole (300 mg/day for six months), evolving to clinical improvement and partial regression of the lung mass, as seen on a second chest X-ray. The current case illustrates an unusual presentation of pulmonary cryptococcosis and raises questions regarding the therapeutic approaches proposed in the literature.
