“…(11)(12)(13)(14)(15) Pulmonary alterations are typically bilateral, predominantly in the middle lobes and spinal cord regions.

Objective: To evaluate the frequency of the real association between paracoccidioidomycosis (PCM) and tuberculosis (TB) as well as the rate of previous TB misdiagnosis in individuals with PCM among the patients treated in the Pulmonology Division of the State University of Campinas Hospital das Clínicas, Campinas, Brazil. Methods: A retrospective study of 227 adult patients with PCM (chronic form) treated between 1980 and 2005. Results: Of the 227 patients studied, 36 (15.8%) had been previously treated for TB. However, only 18 (7.9%) presented positive sputum smear microscopy results. The remaining 18 (7.9%) neither presented positive sputum smear microscopy nor showed improvement after receiving specific anti-TB treatment. Conclusion: Although the existence of an association between PCM and TB has been documented in the literature, misdiagnosis is common due to the superimposition of and the similarity between their clinical and radiographic presentations, thereby warranting the need for bacteriological diagnosis before initiating specific treatment.

Published studies on the association between cancer and paracoccidioidomycosis consist either isolated cases or clinical data based on hospital cohorts of paracoccidioidomycosis. The frequency of neoplasia in series of ! 80 patients with paracoccidioidomycosis ranges from 0.16 to 14.1%, mean of 3.96%. There are only two retrospective controlled studies, one of them showing greater incidence of carcinoma in biopsy and necropsy samples of paracoccidioidomycosis (12 cases in 147 patients with the mycosis: 8.2%) than in the necropsies of the control group (320 cases in 7,302 necropsies: 4.9%). In the other, 22,409 autopsies were reviewed and 4,372 cases of cancer were found; of the 85 patients with paracoccidioidomycosis, 12 were diagnosed with cancer. No differences were observed in the frequency of malignancies between the group of patients with paracoccidioidomycosis (14.1%) and the control group (19.5%). Considering all the reported cases, carcinoma was more frequent than hematological malignancies, and was more often found at the same site or in a neighboring site affected by the mycosis, usually occurring after the diagnosis of the mycosis. Commonly, the basic cause of death was related to secondary infections or neoplasia. Lymphoma was associated with poorly organized rich in fungi granuloma. The clinical course and mortality were related to the cancer evolution or secondary infections and was worse in lymphoid series, metastatic carcinoma or in patients under cytotoxic chemotherapy. Additionally, as in several cases the clinical and histopathological data

Introduction:The purpose of this study was to compare respiratory signs and symptoms between patients with and without chest X-ray abnormalities in order to establish the meaning of radiographic findings in pulmonary PCM diagnosis. Methods: The epidemiological, clinical and radiological lung findings of 44 patients with paracoccidiodomycosis (PCM) were evaluated. Patients were divided into two groups of 23 and 21 individuals according to the presence (group 1) or absence (group 2) of chest X-ray abnormalities, respectively, and their clinical data was analyzed with the aid of statistical tools. Results: As a general rule, patients were rural workers, young adult males and smokers -group 1 and 2, respectively: males (91.3% and 66.7%); mean age (44.4 and 27.9 year-old); smoking (34.7% and 71.4 %); acute/subacute presentation (38.1% and 21.7%); chronic presentation (61.9% and 78.3%). The most frequent respiratory manifestations were -group 1 and 2, respectively: cough (25% and 11.4%) and dyspnea (22.7% and 6.8%). No statistical difference was observed in pulmonary signs and symptoms between patients with or without radiographic abnormalities. The most frequent radiological finding was nodular (23.8%) or nodular-fibrous (19%), bilateral (90.5%) and diffuse infiltrates (85.7%). Conclusions: Absence of statistical difference in pulmonary signs and symptoms between these two groups of patients with PCM indicates clinical-radiological dissociation. A simplified classification of radiological lung PCM findings is suggested, based on correlation of these data and current literature review.
