Paracoccidioidomycosis is a chronic, subacute or rarely acute mycosis, with visceral and cutaneous involvement. It is potentially fatal. Children account for about 5-10% of cases. In this study, we describe the relevance of discussing possible differential diagnoses as well as the importance of early treatment.
Keywords: child; granuloma; paracoccidioidomycosis
Paracoccidioidomicose é uma micose crônica, subaguda ou raramente aguda, com comprometimento visceral e tegumentar, sendo potencialmente fatal. As crianças representam cerca de 5 a 10% dos casos. A seguir, descreve-se a necessidade da discussão dos diagnósticos diferenciais cabíveis bem como a importância do início precoce do tratamento.

Twelve-year old white male student from Boa Esperança, Sao Paulo.
The patient reported appearance of lesions on the face and chest in January 2009. At another service, he had been subjected to a biopsy, which showed multinucleated cells with negative sputum smears and non-visualized nerve fibers. This is consistent with granulomatous dermatitis (July/2009). He was sent to the referral service with suspected leprosy.
On examination, we found erythematous-violaceous infiltrated plaques and papules on the face, ear lobe and anterior chest (Figuras 1, 2 and 3). We also found enlargement of right posterior and anterior cervical lymph nodes (Figure 1). The liver was palpable 4 cm from the right costal margin.
We discussed possible diagnoses, such as paracoccidioidomycosis, leishmaniasis, sarcoidosis, tuberculoid leprosy, and granulomatous syphilis.
The patient underwent a new biopsy, and the anatomopathological finding was consistent with paracoccidioidomycosis (Figure 4). This disease is a chronic, subacute or acute mycosis that may involve the skin and viscera. 1-5
It should be noted that the child was referred to the service with suspected leprosy. This hypothesis, based on initial clinical and histopathological findings, was not entirely wrong, since the tuberculoid pole of the disease spectrum may present sarcoid lesions on clinical examination and well formed granulomas on histological examination.3
To identify paracoccidioidomycosis, we used gel immunodiffusion reactive up to 1:32 and indirect immunofluorescence reactive up to 1:252.
Treatment with itraconazole 200 mg daily was started.
After ten months of treatment, the patient presented no clinical lesions. There was no recurrence after over a year of follow-up and use of medication.
