Paracoccidioidomycosis in a child: exuberant presentation due to the inadvertent use of systemic corticosteroids

Abstract: Paracoccidioidomycosis is a fungal infection that occurs in immunocompetent patients and are classified into two forms: the acute-subacute form, predominantly in young patients, and the chronic adult form that may present classic ulcerated lesions to rare sarcoid ones. We present the case of a boy whose infection began with sarcoid lesions but, after being mistakenly diagnosed with cutaneous sarcoidosis and treated (for three years) with prednisone, developed painful ulcerations throughout the body. After the correct diagnosis, with evidence of the fungus in histopathological and mycological examinations, the patient was properly treated with itraconazole for eight months and evolved with total remission of the disease.

Métodos diagnósticos da escabiose / Diagnostic methods for scabies

Escabiose é infecção cutânea contagiosa causada pela penetração do ácaro Sarcoptes scabiei var. hominis na epiderme. A suspeita diagnóstica é feita pela história, distribuição clínica das lesões e sua aparência, porém sua confirmação se dá com a identificação do parasita. Apresentamos os aspectos dos métodos diagnósticos da escabiose, desde a identificação por microscopia óptica de raspados cutâneos de lesão ou pelo uso de fita adesiva sobre as lesões, à identificação com uso do dermatoscópio, ferramenta presente na maioria dos consultórios dermatológicos e que, mesmo em mãos inexperientes, possui sensibilidade e especificidade aceitáveis.

Scabies is a contagious cutaneous infection, caused by burrowing of the mite Sarcoptes scabiei var. hominis in the epidermis. The clinical suspicion is due to the history, clinical distribution of lesions and its aspect; however, the confirmation is with the detection of the parasite. We present the features of the diagnostic methods for scabies, from its detection through direct microscopy of skin scrapings from a lesion or with the use of an adhesive tape on the lesions, to its detection using the dermatoscope, a tool available in most dermatology clinics, which, even in unexperienced hands, has acceptable sensitivity and specificity.
