ABSTRACT

We report a case of a 43 years-old portuguese man, natural and resident in Madeira island, who was emigrated in Venezuela until 6 years ago. He was observed on March 2008 for a crusted papulo-nodular lesion with erythematous regular borders, pruritic and sized 4,5 x 3,0 cm, located on the dorsum, with a 2 month history. There was no palpable lymphadenopathy. He denied other simptomatology. On March of 1999, the patient had a mouth lesion which was compatible with paracoccidioidomycosis on histopathological examination. He was not aware of any associated pathologies. We performed two punch biopsies of the cutaneous lesion for histopathological and mycological examination.
The histopathology showed the presence of multiple round cells of different size (yeast cells) in a narrow base suggesting the classic “pilot’s wheels”, on Hematoxiline & Eosine stain. On direct microscopic examination the mycology revealed yeast of different sizes – some of them on gemulation. The cultures, at 24º and 37º, isolated Paracoccidioides brasiliensis.
The thoracic x-ray revealed a heterogeneous, bilateral and symmetric pattern located towards the central and basal portions. The CT scan of the chest showed multiple, micronodular and striated lesions (some of them with small cavities), with tendency to coalesce. To characterize better these lung abnormalities, the patient performed a fibrobronchoscopy of the respiratory tract which was normal. The culture, at 25 ºC, obtained from the sputum of the bronchoalveolar lavage fluid (BAL) showed Paracoccidioides brasiliensis.
Routine laboratory studies were normal and serology negative for HIV and tuberculosis. The treatment of choice was itraconazol 200 mg/day, for 6 months. As far as we know no case of PCM has been reported in Madeira. Although it is not a frequent disease outside the endemic areas, dermatologists should be able to recognise and diagnose systemic mycosis like PCM.
