Chromomycosis

Essentials of Diagnosis Patients are usually immunocompetent. Found worldwide but usually in tropical or subtropical areas. Mold in culture; forms sclerotic body or muriform cell in tissue. Infection results from direct inoculation from contaminated soil or vegetative substances. Chronic indolent cutaneous verrucous lesions, most often on the feet. General Considerations Chromomycosis, also known as chromoblastomycosis, is a chronic subcutaneous infection caused by several different fungi. Although rarely seen in the United States, it is common worldwide. A. Epidemiology. Chromomycosis occurs worldwide but is most frequently encountered in tropical and subtropical regions.

Aspergilloma

An aspergilloma of the lung may develop in individuals who have preexisting cavitary lung disease caused by conditions such as tuberculosis, sarcoidosis, silicosis, or bronchiectasis. Also known as a fungus ball or mycetoma, aspergillomas can be regarded as heavy Aspergillus colonization of the preexisting cavity. Clinical Findings A. Signs and Symptoms. The most common symptom is hemoptysis, and, on rare occasions, severe or fatal hemoptysis can develop. Other symptoms are usually related to the underlying lung disease. B. Laboratory Findings. Patients with an aspergilloma of the lung typically have elevated IgG levels specific for Aspergillus spp. Sputum smear may show the presence of filamentous fungi, and culture is intermittently positive for …

Actinomycetes

Actinomycetes are variably acid-fast, gram-positive bacilli that are sometimes filamentous and branched. Originally thought to be fungi due to their hyphae-like appearance, they are now recognized as bacteria based on their cell wall components, reproduction by fission without sporulation or budding, inhibition by antibacterial agents, and molecular phylogenetic analysis. The actinomycete chromosomes contain a high content of guanosine and cytosine. The actinomycetes include the genera Mycobacterium and Corynebacterium, which are discussed in site and site, respectively. The actinomycetes also include the genera Nocardia, Actinomyces, Rhodococcus, Tsukumurella, Gordona, Actinomadura, and Streptomyces, as well as the Whipple’s disease bacillus Tropheryma whippelii. Of these, members of the genus Nocardia are the most significant from …

Nocardia

Essentials of Diagnosis Gram-positive, variably acid-fast, branching filaments with aerial hyphae. Colonies have characteristic chalky-white or cotton ball appearance. Suspect when chronic pulmonary disease is accompanied by CNS or skin lesions. No specific antibody or antigen detection tests. General Considerations A. Epidemiology. Nocardia spp. are strictly aerobic, ubiquitous soil-dwelling organisms that are largely responsible for the decomposition of organic plant material. Infection usually occurs via inhalation of these organisms in airborne dust particles, leading to pulmonary disease. However, infection can also be acquired via direct percutaneous inoculation by thorns, animal scratches, bites, surgical wounds, and intravenous catheters. Dissemination commonly occurs to the central nervous system (CNS), skin, and subcutaneous tissues. Nocardiosis …

Tuberculosis: Clinical Syndromes

PULMONARY TUBERCULOSIS The most common syndrome in adults is pulmonary TB, which accounts for ~ 80% of cases of active disease. Clinical Findings A. Signs and Symptoms. Symptoms of infection consist of fatigue, weight loss, fever, night sweats, and a productive cough. Most children who are infected with TB usually have no symptoms. Early symptoms can also include hemoptysis, which also occurs later in the disease when there is significant necrosis of lung parenchyma or if previous cavitations erode into arterioles. Patients with subpleural parenchymal inflammation with pleural membrane involvement or with TB pleuritis without parenchymal disease can experience pleuritic chest pain. Severe shortness of breath is not common. However, extensive …
