Introdução: A paracoccidioidomicose (PCM) é uma micose sistêmica endêmica causada pelo fungo Paracoccidioides spp. O objetivo deste estudo foi determinar a associação entre tuberculose (TB) e PCM em pacientes com exame micológico negativo. Métodos: Estudo prospectivo de diagnóstico molecular de amostras de escarro, com resultado positivo para bacil...

Introduction: Actinomyces and Nocardia are filamentous bacteria that can simulate neoplastic diseases, mainly in lungs. Methods: A retrospective study based on the analysis of the medical records of five cases of actinomycosis and nocardiosis, which has been primarily misdiagnosed as lung cancer according to their radiographic findings. Cases were...

Infections that simulate neoplasia are uncommon. In a retrospective study we included all cases of histoplasmosis, cryptococcosis due to Cryptococcus gattii, actinomycosis and nocardiosis mimicking malignancy. The sample consisted of 80 cases extracted from a population of 1,365 during the period 1981-2012. We review critically the cases reported a...

Cryptococcus gattii are closely related species of encapsulated yeast-like fungi involved in the etiology of cryptococcosis, especially in immunocompetent individuals. Dissemination with involvement of many organ systems is common. On the other hand, cellulitis in an immunossupressed patient caused by C. gattii is rare. We present a case of dissemi...

We present a case of histoplasmosis with multiple pulmonary nodules in a patient with a history of melanoma. This case closely simulated malignancy, including the presence of feeding vessel sign, which occurs in pulmonary metastasis. We emphasize the need to be aware of this infection in areas where histoplasmosis is endemic.

Paracoccidioidomycosis (PCM) is an endemic disease restricted geographically to Latin America. Brazil accounts for about 80 % of the reported cases, and lungs are most frequently affected. A suggestive radiograph of PCM may only be seen late in the course of the disease. At the beginning, it mimics tuberculosis. On the other hand, pleural effusion...

Objective: To describe the main clinical and radiological characteristics of patients with histoplasmosis mimicking lung cancer. Methods: This was a retrospective descriptive study based on the analysis of the medical records of the 294 patients diagnosed with histoplasmosis between 1977 and 2011 at the Mycology Laboratory of the Santa Casa Sist...

Hospitals around the world have presented multiresistant Acinetobacter sp. outbreaks. The spread of these isolates that harbor an increasing variety of resistance genes makes the treatment of these infections and their control within the hospital environment more difficult. This study aimed to evaluate the occurrence and dissemination of Acinetobac...

We report a case of disseminated paracoccidioidomycosis, initially suggestive of metastatic lung cancer. The infection was associated with strongyloides hyperinfestation as a result of iatrogenic hypercorticoidism. Examination of a smear prepared from aspirated tracheobronchial secretion and stained by Grocott-methenamine-silver revealed structures...
