Objective To summarize the characteristics of disseminated Penicillium marneffei infection.Methods The clinical, imageological and bacteriological characteristics were summarized by reviewing one case of disseminated Penicillium marneffei infection in an immunocompetent patient diagnosed in our hospital and the related literatures. Results The patient was a 32-year-old Guangdong male, whose main clinical features were fever, cough, and the abscess of pulmonary, tracheomucosa and subcutaneous. Routine blood examination showed leukocytosis. Other laboratory examination revealed multiple lesions of heart, liver, and kidney. Multiple masses histopathology revealed inflammation, but the culture from the purulent exudates were negative and standard antibiotic therapy was useless. Bronchoscope revealed gray nodus on airway mucosa. Under the direction of bacteriologist, final diagnosis of Penicillium marneffei infection was obtained by the fungal culture from the purulent exudates and the deep sputum. Conclusions Penicillium marneffei can infect immunocompetent patients. Disseminated Penicillium marneffei infection should be considered when patients presented with multiple organ lesions and multiple subcutaneous pyogenic masses which can not explained by connective tissue disease or common pyogenic infection, and with epidemiology of southeast life history.
Objective To investigate the clinical features of hypersensitivity pneumonitis and misdiagnosis causes. Methods The morbidity, misdiagnosis, progression, treatment, recovery, relapse and experience of treatment of a case with hypersensitivity pneumonitis was retrospectively analyzed. Results Patients with hypersensitivity pneumonitis usually have a contact history of organic dust, and clinical manifestations are nonspecific. Chest radiography shows wandering pattern of multiple reticular or patchy infiltration shadows. Lung function tests showrestricted ventilation and impaired diffusion. Blood eosinophil is usually normal. Lymphocyte and sedimentation antibody in serum and bronchoalveolar lavage fluid may still be normal. Pathohistology is complicated, with a progression from acute inflammation to chronic fibrosis. Systemic steroid should be prescribed as soon as possible. Antigen avoidance should be emphasized. Conclusions Clinical symptoms of hypersensitivity pneumonitis is atypical, which may be easily misdiagnosed. The contact history, clinical features, chest radiography, laboratory examination and pathological changes should all be considered in such cases.
