Paracoccidioidomycosis: a series of 66 patients with oral lesions from an endemic area
Mycoses, 2011
America. It has been regarded as a multifocal disease, with oral lesions as the prominent feature. To provide useful information concerning the diagnosis and management of the disease, this study describes demographic and clinical data from the medical records of a consecutive series of 66 Brazilian patients from an endemic area, evaluated in a referral centre for oral diagnosis. In this sample of patients, there was a predominance of middle-aged male patients, who were primarily rural workers. Chronic multifocal disease was prevalent, with lesions also detected in the lungs, lymph nodes, skin or adrenal glands. Most of the cases presented with lesions at the gingival mucosa followed by the palate and lips; these conditions occurring in the oral cavity were frequently associated with pain. Importantly, most of the patients sought professional care for oral lesions. The diagnosis was obtained through exfoliative cytology and ⁄ or biopsy of the oral lesions. Medical treatment was effective, and there were no mortalities in the sample. The present findings not only confirm the importance of oral lesions in the diagnosis and management of PCM but also illustrate that questions still remain unclear, such as the possibility of direct inoculation of the fungus onto oral tissues.
Oral Paracoccidioidomycosis: A Case without Lung Manifestations
The Journal of Contemporary Dental Practice, 2007
Aim The aim of this article is to present a case of Paracoccidioidomycosis with involvement of the oral cavity but without pulmonary manifestations. Background Paracoccidioidomycosis is a fungal infection caused by Paracoccidioides brasiliensis. It is an endemic disease representing a serious health problem for Latin American countries, especially Brazil. This infection primarily affects the lungs of adult men and is acquired through inhalation or accidental inoculation of the fungus. It can spread to other organs and tissues, mainly the oral cavity. Administration of antifungal medication always resolves the disease. Report A 58-year-old black male presented with three painless, ulcerated, mulberry-like granulomatous lesions located in the floor of the mouth, on the superior alveolar ridge, and on the hard palate, which had evolved over a period of two years. Facial asymmetry was observed due to edema in the lower lip and lymphadenopathy. He had smoked for more than six years but s...
Oral Manifestations Associated to Paracoccidioidomicosis and Histoplasmosis
Pesquisa Brasileira em Odontopediatria e Clínica Integrada
Objective: To determine the frequency and clinical forms of oral manifestations associated to Paracoccidioidomycosis (PCM) and Histoplasmosis. Material and Methods: 481 medical records of outpatients referred to the Medical Mycology Department were reviewed since 2009 to 2016. Data were analyzed using descriptive statistical methods. Results: 47 (9.77%) cases had oral manifestations, 29 (61.70%) were associated to PCM and 18 (38.29%) to histoplasmosis. For PCM, male-female ratio was 8:1 and 1:1 for histoplasmosis. The average age for PCM was 48 years old and 53 for histoplasmosis. All the PCM patients had more than 1 oral structure affected: 44.82% were gingival lesions and 27.58% palate. In patients with histoplasmosis, 6 (33.33%) were lesions affecting palate and 6 (33.33%) involving tongue. For both entities, painful ulcers and granulomatous-like lesions were the most prevalent clinical forms; however, we observed a wide range of other oral manifestations. Regarding PCM patient's comorbidities, 3 (10.34%) cases had HIV/AIDS, 8 (27.58%) histoplasmosis and 2 (6.89%) carcinomas. Whereas the comorbidities of patients with histoplasmosis, 2 (11.11%) had HIV/AIDS and 1 (5.55%) had carcinoma. Conclusion: In endemic countries for both mycoses, dentists must be aware of patients with mouth lesions, take advantage of epidemiologic clues that suggest risk factors and be acquainted with all the current diagnostic tests in order to make a quick diagnosis and treatment in highly suspicious cases.
International journal of odontostomatology, 2014
This article describes a case of recurrence of chronic paracoccidioidomycosis (PCM) 11 years following the initial diagnosis. The patient was a 51-year-old white Brazilian female, which had been previously diagnosed with PCM. The physical examination revealed the presence of a single crusted lesion in the upper lip and an elevated lesion with fibrous scar appearance on right buccal mucosa. Although the diagnosis of PCM, the absence of pulmonary involvement led to the biopsy of the lesion localized on the buccal mucosa and the histopathological analysis in H&E and PAS stains revealed no morphological changes suggestive of any lesion. However, the exfoliative cytology stained with Grocott-Gomori showed the presence of Paracoccidioides brasiliensis and the infection caused by this fungus was proven. Of this way, we emphasize the importance of stomatologic evaluation to the diagnosis of diseases that usually manifestssystemically. So, the correct diagnosis of oral manifestations of PCM, is essential to ensure early and safe intervention.
Gingival Involvement in Oral Paracoccidioidomycosis
Journal of Periodontology, 2007
Background: Paracoccidioidomycosis, a deep mycosis endemic in parts of Latin America, often presents with oral lesions involving the gingiva. Nevertheless, the periodontal literature is devoid of references to oral paracoccidioidomycosis. The purpose of this study was to characterize the gingival involvement in oral paracoccidioidomycosis and to contrast clinical and histopathologic diagnosis of the disease. Differential diagnosis and management of oral paracoccidioidomycosis were reviewed.
Value of exfoliative cytology in diagnosis of oral paracoccidioidomycosis - case report
Polski Przegląd Otorynolaryngologiczny, 2016
Paracoccidioidomycosis is a systemic mycosis caused by inhalation of the fungus P. brasiliensis. The primary infection involves the lungs and can spread to other organs and systems resulting in secondary lesions in the mucosa, lymph nodes, skin and adrenal glands. Oral lesions are insidious in progression and can be multifocal. The aim of this study was to report a case of paracoccidioidomycosis in a patient who was misdiagnosed with pulmonary tuberculosis. A 40-year-old male, HIV-positive, was admitted with complaints of weight loss, asthenia, diarrhea, coughing and dyspnea. Physical examination revealed the presence of caries, coated tongue, residual roots, oral candidiasis and ulcerated, granulomatous lesions in the hard palate and alveolar ridge. Laboratory tests revealed anemia, neutrophilia and an increased erythrocyte sedimentation rate. Cytology and incisional biopsy were performed. The cytological examination revealed the presence of fungus and the pathological examination confirmed the diagnosis of paracoccidioidomycosis. The doctors who previously made the diagnosis of tuberculosis were informed of the new diagnosis, as the patient was being treated for tuberculosis. The treatment for paracoccidioidomycosis was initiated and the patient is under clinical monitoring.
Single Oral Paracoccidioidomycosis Mimicking Other Lesions: Report of Eight Cases
Mycopathologia, 2012
Paracoccidioidomycosis is a fungal infection caused by Paracoccidioides brasiliensis. It is an endemic disease, representing a serious health problem in Latin American countries. This infection primarily affects the lungs and is acquired by inhalation of the fungus. It can spread to other organs and tissues, mainly the oral cavity affecting more adult men from 30 to 50 years of age. On clinical presentation, several signs associated with impaired general and nutritional conditions can be noted. Oral manifestation is more common in the soft palate, gingiva, lower lip, buccal mucosa, and tongue. The classical clinical presentation is a superficial ulcer with granular appearance and hemorrhagic points. Usually, the oral lesion is extensive and generalized. Although uncommon, when the oral manifestation is single, others lesions, particularly squamous cell carcinoma, must be included in the differential diagnosis. In this article, the authors discuss the unusual presentation of eight cases of single oral paracoccidioidomycosis and its diagnostic importance.
Case of Recurrent Paracoccidioidomycosis in Female 10 Years after Initial Treatment
The Bulletin of Tokyo Dental College, 2007
This report describes a case of recurrence of chronic paracoccidioidomycosis 10 years following the initial diagnosis. A 56-year-old female was admitted to the Dental Clinic of the Pontifical Catholic University of Paraná complaining of oral soreness. Mulberry-like ulcerations were observed on the gingiva, right labial comissura, and vermillion of the lip. The patient reported persistent chronic cough, weight loss, appetite loss and fever. The anamnesis revealed that the patient had developed and been treated for paracoccidioidomycosis 10 years earlier. A biopsy was performed and microscopic examination revealed microabscesses, collections of macrophages organized into granulomas, multinucleated giant cells and Paracoccidioides brasiliensis. The patient was treated with Itraconazole and, the oral lesions disappeared within 3 months. Persistent follow-up examination in patients with a history of paracoccidioidomycosis is essential in the management of this disease.
Informe de caso: Paracoccidioidomicosis crónica multifocal del adulto
Colombia …, 2011
Paracoccidioides brasiliensis is the ethiological agent of one of the most prevalent systemic mycosis in Latin America, where around ten-million individuals are affected. Brazil has the highest incidence but in Venezuela, Colombia, Ecuador, and Argentina cases have also been reported. We describe a 56-year-old male with a one year history of lip, oral mucosa, and lung lesions. Granulomas and multinucleated giant cells were observed in histopathological evaluation with haematoxilyn-eosin stain. Mycologic studies (KOH and Gomori Grocott stain) showed blastoconidias with multiple budding. Serologic tests for paracoccidioidine were reactive. A diagnosis of chronic multifocal paracoccidioidomycosis was made. Initially, amphotericin B 0.7 mg/kg per day was started for fifteen days and consecutively itraconazole (400 mg/day) was administered orally with improvement of skin and lung lesions; however, an important residual fibrosis was observed. The patient was lost to follow up. We highlight the importance of an early diagnosis and adequate treatment to decrease sequelae in patient quality of life.
