title: Co-existence of integumentary lesions and lung x-ray abnormalities in patients with paracoccidioidomycosis (PCM).
abstract: In paracoccidioidomycosis (PCM), the primary lung infection remains silent. In this study, attempts were done to define the primary target organ by correlating lung radiographic abnormalities with the time course of mucosal/skin lesions concurrently exhibited at diagnosis by 63 patients in whom microscopy and/or isolation of Paracoccidioides brasiliensis from respiratory secretions had been positive. Mucosal and skin lesions were found in 65.1% and 12.7% of the patients, respectively. Odynophagia and dysphagia were present in 38.1% each. All patients had lung interstitial infiltrates, and 31.7% had also alveolar lesions; fibrosis was recorded in 46% of them. An inverse correlation was shown for fibrosis and presence of either odynophagia or dysphagia. Cluster analyzes strongly supported two sets of patients: those with mucosal damage, odynophagia/dysphagia, and alveolo-interstitial infiltrates and those with dermal lesions, dyspnea, and lung fibrosis. These groups may represent novel stages in the natural course of PCM.
