Abstract
Purpose of Review The increase in international travel in recent decades has contributed to the risk of acquiring diseases considered endemic to a region or country and the change in the epidemiology of these diseases. Endemic mycoses that may be acquired by travelers in the short or long term are endemic subcutaneous mycoses such as sporotrichosis and lobomycosis, while endemic systemic mycoses are a group of serious diseases including histoplasmosis and coccidioidomycosis. Herein, we review the current knowledge and highlight the most important aspects of these fungal infections in travelers. Recent Findings The most relevant advances in the study of these mycoses involve the epidemiological distribution; human mycoses can be fatal and there are few antifungal drugs available, increasing drug resistance, and a risk of emerging fungal diseases associated with climate change, as well as the increasing virulence, and the diagnostic strategies that may be limited in many countries. Summary Although endemic mycoses are relatively rare, they should be considered as potentially travel-related illnesses. A recent or late trip to an endemic country may guide the clinical suspicion, an early diagnosis, and the institution of effective therapy.

Abstract
Paracoccidioidomycosis (PCM) is a systemic granulomatous disease caused by Paracoccidioides brasiliensis or P. lutzii. It is a neglected tropical infectious disease that poses a major public health burden in endemic areas of Latin America. Mucosae of the upper digestive and respiratory tracts are commonly involved and many patients have disease at multiple mucosal sites, with or without lung involvement. Mucosal PCM presenting as solitary true vocal fold disease is relatively rare. We present the case of a 67-year-old Brazilian forest guard who presented with a 6-month history of hoarseness and globus pharyngeus due to a solitary left true vocal fold infiltration and vegetation diagnosed as PCM. Silent pulmonary disease was also present. A laryngoscopy video is offered as supplemental material to this report. He completely remitted after surgical removal and amphotericin B deoxycholate treatment.

Abstract
INTRODUCTION Paracoccidioidomycosis is a disease that is endemic to southern and southeastern Brazil, caused by the fungus Paracoccidioides brasiliensis. The most common clinical oral manifestation is the presence of multiple granulomatous ulcers with hemorrhagic dots, located mainly on the lips, palate, and buccal mucosa. However, the disease can manifest atypically as a single ulcer, mimicking oral squamous cell carcinoma (SCC) or tuberculosis. CASE REPORT A 65-year-old male patient presented with a complaint of a single ulcerated lesion on the dorsum of the tongue; the lesion had evolved over 6 months. The diagnostic hypotheses were SCC and oral manifestation of tuberculosis. An incisional biopsy was performed, and histopathological analysis of the specimen revealed pseudoepitheliomatous hyperplasia, a granulomatous structure of epithelioid histiocytes, multinucleated giant cells, and lymphocytes in the connective tissue. Grocott staining confirmed the presence of the fungus in the lesion, and a diagnosis was made of paracoccidioidomycosis. The patient was treated with 200 mg/day of itraconazole for 12 months and now shows no signs or symptoms of recurrence of the disease. CONCLUSION Correct diagnosis is essential for a successful therapeutic approach and resolution of the lesion.

Abstract
Paracoccidioidomycosis is the most common deep mycosis in South America and is caused by Paracoccidioides brasiliensis (P. brasiliensis), a thermally dimorphic fungus. Infections usually occur by inhalation of conidia, which more often cause respiratory, mucocutaneous, and lymph nodal changes. Chronic features of this mycosis can mimic diverse infections and malignancies and constitute diagnosis challenges. Squamous cell carcinoma deserves special attention in this setting. We describe the case of a patient with synchronous diagnosis of oral paracoccidioidomycosis and esophageal squamous cell carcinoma. Concomitance of these conditions may be a casual event, but a not fully understood causal relationship can be involved.

Abstract
South American blastomycosis, paracoccidioidomycosis (Pb mycosis) or Lutz disease is an endemically fungal infection in Latin America. It is caused by the dimorphic fungus Paracoccidioides brasiliensis and may cause oral mucosal lesions. The incidence of Pb mycosis oral lesions was evaluated in patients assisted at a Brazilian Dental School's Specialized Oral Diagnosis Service with special focus on the different clinical forms of these lesions, its location, patients' occupation, deleterious habits, and diagnosis methodology. Students' and professionals' initial diagnoses were compared with the definitive diagnosis. Lesions were detected 31 cases (18 patients). The results show that 88.8% of the patients were male with a mean age of 50 years and 39% work(ed) with activities related to agriculture. As much as 88.9% were smokers and 72.2% were alcohol users. Exfoliative cytology was performed in 66.6% of the patients. Oral mucosa (30%), gingiva (16.6%) and lips 16.6% were the most common sites of Pb mycosis oral lesions. Comparing the initial with the definitive diagnosis made by the professionals their accuracy was 33% (6 out of 18 patients). Students' diagnosis was more accurate demonstrating 72.5% of initial correct diagnosis (13 out of 18). Statistical analysis by ANOVA (α=0.05, SPSS WIN) demonstrated a significant difference between the diagnosis of Pb mycosis made by students and professionals when considering initial diagnosis and final diagnosis (after histopathological analysis) (p=0.25). Incisional biopsy and exfoliate cytology are efficient for an early diagnosis of this disease in mouth. Students' training in diagnosis of oral pathologies to recognize lesions is urgent to improve public health.

Abstract
Paracoccidioidomycosis (PCM) is the most prevalent systemic mycosis in immunocompetent individuals in Brazil. Ocular infection by PCM is rare; however, when infection does occur, the most common ocular sites involved are eyelid and conjunctiva. A 68-year-old white male presented with a 2-month history of a painless, ulcerated, infiltrative and diffuse whitish lesion located on the right inferior eyelid. A clinical diagnosis of malignant tumor, possibly squamous cell carcinoma, was made. The histopathologic examination showed a hyperplastic epithelium with inflammatory infiltrate of lymphocytes, plasma cells, neutrophils and histiocytes. Large numbers of giant cells were also present. Periodic acid Schiff and Grocott (silver methenamine) stains showed several large round structures with peripheral lateral small budding cells that resembled a "ship's wheel". No multinucleated fungi were seen. The fungi varied in size and small forms were round and single fungal structures. A diagnosis of paracoccidioidomycosis was made PCM eyelid infection is rare and can simulate carcinoma both clinically and histopathologically.

Abstract
Oral paracoccidioidomycosis and oral squamous cell carcinoma may occur in the same patient. As both lesions may present similar clinical and histopathological features, the diagnosis is sometimes challenging. This paper describes the case of a 54-year-old male who was a farm worker and heavy alcohol and tobacco user. He developed paracoccidioidomycosis and two lesions of squamous cell carcinoma in the oral cavity. During the follow-up, the patient presented enlargement of the submandibular lymph nodes, which was thought to be regional metastasis but was diagnosed as paracoccidioidomycosis. Therefore, the significance of this association is emphasized and discussed.

Abstract
Stomatologic fungal infections display different etiologies, pathogenesis, and clinical presentations. The incidence of rare mycoses of oral cavity is very low. These infections can involve both immunocompromised and immmunocompetent patients with common predisposing factors, such as diabetes or suffering from diseases causing immune system impairment. Oral mycoses can cause acute, chronic, and mucocutaneous lesions. Candidiasis is the most common mouth mycosis. Although occasionally primary mouth pathogens, Cryptococcus spp. or filamentous fungi (Aspergillus spp. and zygomycetes) can cause oral mycoses, with the oral localization more commonly secondary to a more serious systemic infection. The diagnosis of oral mycoses is based on clinical examination; for yeasts, culture is necessary to identify the etiologic agents; for filamentous fungi, in particular for zygomycetes and dimorphic, a definitive diagnosis can be made by histologic examination and pertinent stains with or without isolation of the fungus from the same site.
