ABSTRACT
Abstract Paracoccidoiomycosis is a systemic mycosis with a higher incidence in males with history of exposure to the rural environment; its classic clinical manifestation is an oro-pulmonary lesion. The authors report a case of a female, urban, 76-year-old patient with atypical clinical-dermatological presentation and diagnostic conclusion after histopathological examination. The clinical response was quick and complete after treatment with itraconazole 400 mg/day in the first month, decreased to 200 mg/day until the sixth month of treatment.

Abstract Cutaneous tuberculosis is a rare extrapulmonary manifestation of tuberculosis which, like disseminated tuberculosis, commonly occurs in immunocompromised patients. Poncet reactive arthritis is a seronegative arthritis affecting patients with extrapulmonary tuberculosis, which is uncommon even in endemic countries. We report a previously healthy 23-year-old male patient with watery diarrhea associated with erythematous ulcers on the lower limbs and oligoarthritis of the hands. Histopathological examination of the skin showed epithelioid granulomatous process with palisade granulomas and central caseous necrosis. AFB screening by Ziehl-Neelsen staining showed intact bacilli, the culture was positive for Mycobacterium tuberculosis, and colonoscopy revealed multiple shallow ulcers. Disseminated tuberculosis associated with reactive Poncet arthritis was diagnosed, with an improvement of the clinical and skin condition after appropriate treatment.
