A case of imported paracoccidioidomycosis: an awkward infection in The Netherlands.
Paracoccidioidomycosis is an important endemic mycosis in South America. In Europe the disease is very rare and only found as infections in travelers to Latin America. We report here the first case encountered in the Netherlands for which the appropriate diagnosis was not attained for several months. A Dutch 60-year-old man presented with a painful ulceration in the buccal mandibular vestibular mucosa of three months duration. While his medical history was uneventful, he had worked, until 8 years prior to his presentation, as a carpenter for 25 years in the jungles of Peru and Ecuador. An aberrant chest radiograph, CT-scan of the lungs and increased erythrocyte sedimentation rate were suggestive of sarcoidosis or a bronchiolitis obliterans organizing pneumonia. There was no improvement in the patient's symptoms despite the use of budesonide and prednisone medication, as well as tuberculosis prophylaxis with isoniazide and rifampicin, and local use of miconazole. Quite to the contrary, as an irritated, irregular hyperemic mucosa and gingiva with ulceration were noticed during this period of time. These precipitated an incisional biopsy through which a mixed inflammatory cellular infiltrate and large yeast cells were found on histopathologic examination. Based on the patient's travel history and the multiple budding yeastlike cells revealed in the biopsy tissue, the diagnosis of paracoccidioidomycosis was finally made. This was supported by the isolation of Paracoccidioides brasiliensis in culture. Antimycotic oral therapy with itraconazole was started and continued for 15 months. At two and five year follow-ups, the patient was asymptomatic. In Europe, it may be expected that diseases that are endemic in other areas will be seen more frequently in countries where the diseases are not routinely encountered. It is most likely that the use of corticosteroid medication, with its inherent immunosuppressive effect, resulted in the reactivation of an infection acquired many years before in Latin America. The etiologic agent then disseminated from the initial focal point to cause the ensuing oral mucous membrane lesions. The importance of the patient's prolonged residence in Latin America was overlooked. The very long latency of endemic mycoses emphasizes the need for a meticulous history which should include not only recent trips, but also past residence in foreign countries.
