The clinical courses of 14 children with acute pulmonary blastomycosis were studied. All the patients had a remarkably similar illness limited to the lungs with fever, malaise, and respiratory symptoms (cough, sputum production, chest pain, and vomiting). Despite eventual recovery with treatment in all instances, 13 of the 14 children persisted in having abnormal roentgenograms. Three children have demonstrated persistent mild obstructive airway disease for two to 12 months after completion of therapy. These data suggest that the initial illness following childhood infections with Blastomyces dematitidis is usually an acute pulmonary disease without systemic dissemination. Evidence of residual lung abnormalities conflicts with the recent concept of this being a benign, self-limited illness. Our findings suggest the importance of long-term follow-up as well as a need for more complete understanding of the full clinical spectrum and prognosis of acute pulmonary blastomycosis.

A 47-year-old woman presented with cough, pleuritic chest pain and fever of three weeks duration. Although the patient lived in an area where blastomycosis is endemic, this diagnosis was not initially considered owing to the presence of consolidation and a large pleural effusion on the initial chest roentgenogram. Cultures of sputa, bronchial washings and pleural fluid documented the presence of pleuropulmonary infection with Blastomyces dermatitidis. Therapy with amphotericin B was associated with rapid clinical, roentgenographic and bacteriologic resolution of both pleural and parenchymal lung disease.

Although blastomycosis is prevalent in the North American continent, it occurs only sporadically in Africa. We describe a 42 yr old patient who complained of intermittent cough and haemoptysis. Clinical findings were strongly suggestive of lung cancer. The diagnosis of pulmonary blastomycosis was made at thoracotomy. This rather unusual disease in our areas caused a considerable delay in securing the diagnosis and we suggest that this infection may be found elsewhere in Africa and the distribution may be wider than has previously been suspected.

The clinical and epidemiologic features of 73 patients with laboratory-confirmed blastomycosis who were identified over an 11-year period in North Central Wisconsin are presented. Pulmonary disease was the sole manifestation in 77% of patients. More than one-half of all patients had symptoms that included fever, cough, weight loss, night sweats, and pleuritic chest pain. Virtually all were previously healthy, and most did not have an outdoor occupation. However, 82% of these patients lived or had visited within 500 m of rivers or associated waterways. The majority experienced the onset of symptoms between December and April. The estimated mean annual incidence rate of infection for Vilas County was 40.4 cases per 100,000 persons, and that for the largest city in the county was 101.3 cases per 100,000 persons. Several areas with an exceptionally high incidence of the infection were observed. We suggest that, in regions where blastomycosis is hyperendemic, clinical disease is most often pulmonary and occurs in immunocompetent individuals and that residence near an ecological focus may be a greater risk factor for acquisition of blastomycosis than is occupation.

The authors reviewed the computed tomographic (CT) scans in 16 patients with pulmonary blastomycosis to describe the abnormalities seen at CT. The CT features were as follows: mass lesions (n = 14), consolidation (n = 9), air bronchograms (n = 14), intermediate-sized nodules (n = 12), satellite lesions (n = 11), pleural thickening (n = 4), small effusions (n = 2), and cavitation (n = 2). One patient had noncalcified hilar lymphadenopathy. Eight patients had acute disease, six had chronic disease, and two had acute exacerbation of a chronic illness. Fifteen patients had cough, fever, and/or dyspnea. Two patients underwent surgical resection for the presumptive diagnosis of bronchogenic carcinoma. In general, there was no correlation between the radiologic abnormalities and the clinical presentation. Consolidation occurred more frequently in acute disease. CT may be useful to help define the radiologic findings and distribution of disease. Familiarity with the characteristic CT findings of pulmonary blastomycosis may encourage an expeditious diagnostic approach to identify the disease and, possibly, prevent unnecessary surgical resection.

Most cases of blastomycosis are sporadic and only nine outbreaks representing a total of 112 cases have previously been reported. Less than half of these have been culture proven cases. Outbreaks have previously occurred in North Carolina, Minnesota, Illinois, Wisconsin and Virginia. We report three culturally confirmed cases of blastomycosis from Elizabethton, Tennessee, who had onset of illness within a one-week span of time. The patients presented with fever, chest pain, weight loss, poor appetite and myalgia. Each initially had a dry cough which became productive of purulent sputum as the illness progressed. Mild hemoptysis occurred during each patient's course. Serologic testing by immunodiffusion and enzyme immunoassay were positive and testing by complement fixation was negative in each case. The diagnosis was made by histopathology on transbronchial biopsy or transthoracic needle aspiration material. Each patient improved on ketoconazole therapy.

A 36-year-old man developed blurred vision and a cough five months after traveling to an area from where a large outbreak of acute blastomycosis had been reported. Examination revealed a left choroidal lesion in the macular region, skin lesions on the right calf, and a left lung apical infiltrate. Histopathologic examination of the skin lesion demonstrated a granulomatous inflammation and broad based, budding yeast characteristic of Blastomyces dermatitidis. Amphotericin B therapy produced a rapid resolution of both choroidal and pulmonary lesions. During a six-month follow-up, there was no evidence of recurrence.

Epidemics of pulmonary blastomycosis have rarely been reported. The following epidemic occurred in a Minnesota family and several of their acquaintances after a canoeing trip in northwestern Wisconsin. The common exposure area was most likely a campsite, located along the upper reaches of the Namekagon River. The Namekagon River Valley is a known endemic area of Namekagon fever (blastomycosis) in dogs. Approximately one month after returning home, five of the eight members of the group had positive direct microscopic examinations and cultures of Blastomyces dermatitidis from their sputa, as well as abnormalities on their chest roentgenograms. Among these five patients, four were symptomatic, with fever, cough, and pleuritic chest pain. Of the three others, one had pleuritic chest pain with a transient lung infiltrate, the second was asymptomatic with a transient lung infiltrate, and the third was asymptomatic with a normal chest roentgenogram. Results of acute serologic tests (complement fixation and immunodiffusion) were negative in all five patients evaluated. None of the patients received antifungal therapy. Follow-up five years after the epidemic revealed that all eight were in excellent health, and none had evidence of continuing pulmonary or extrapulmonary disease.

Children acquire blastomycosis, with rare exceptions, through the respiratory route. Nearly half of those who are infected may be asymptomatic. Cough is the most common symptom and is usually without sputum production, and hemoptysis is not noted. Other symptoms are chest pain (described as tightness or pain when breathing), weight loss, night sweats, and loss of appetite. The severity of illness is variable and may simulate an upper respiratory infection, bronchitis, pleuritis, or pneumonia. As in adults, an overwhelming infection may cause respiratory failure even in immunocompetent children and in immunocompromised children who live in or travel to endemic areas are susceptible to infection. Some reports based on consecutive cases note extrapulmonary dissemination commonly in children, whereas dissemination is rarely noted in outbreak cases. Chronicity of the disease favors extrapulmonary dissemination. Chest radiograph patterns are alveolar infiltrates, consolidation, and nodule(s), and these may be accompanied by cavitation. Diagnosis is suspected when the symptoms that mimic common respiratory infections persist for more than 2 weeks and by a history of residence or travel to an endemic area. Chest radiographic findings of nodule(s) or cavitation further increase the suspicion. Confirmation of diagnosis is by microscopic examination and culture of sputum. When expectorated sputum is unavailable, bronchoscopy with lavage and biopsy or percutaneous needle biopsy of lung is the appropriate next step. Disease that is progressive or severe or disseminated to other organs should be treated. Amphotericin B is effective and results in excellent cure rates. Experience using oral azoles is limited in children.

An 8-year-old male rhesus monkey (Macaca mulatta) died following a 6-day illness consisting of progressive depression, anorexia, labored abdominal breathing, coughing, and tachypnea. Gross necropsy findings included severe multifocal (miliary) granulomatous pneumonia, granulomatous splenitis, and multifocal cerebral abscesses. Histologic examination revealed 10-15-microm broad-based budding organisms within pyogranulomatous inflammatory lesions in the lung, tracheobronchial lymph node, brain, spleen, and liver. The distribution of extrapulmonary lesions was intermediate between that described for dogs and that described for humans. These findings were consistent with blastomycosis, which is previously unreported in nonhuman primates.
