Sporotrichosis in children is rare, and its osteoarticular form is very unusual. Disseminated forms are described mostly in immunocompromised patients. We report a case of a 5-year-old immunocompetent boy with multiple suppurated cutaneous lesions that progressed to polyarthritis of the hands and feet. Radiographic imaging demonstrated multifocal lytic lesions. Sporotrichosis was diagnosed through biopsy and culture. This article describes the radiographic appearance of a rare manifestation of this disease. In areas of high prevalence, the diagnosis of sporotrichosis should be taken into account, even in immunocompetent patients, when dactylitis with lytic lesions is present.

OBJETIVO: Descrever os aspectos tomográficos da tuberculose pulmonar primária manifestada inicialmente como consolidação lobar. MATERIAIS E MÉTODOS: O trabalho foi realizado no Hospital Municipal Jesus, Rio de Janeiro, RJ, no período de 2002 a 2006, avaliando-se retrospectivamente os aspectos tomográficos de quatro crianças de 3 a 14 meses de idade com tuberculose pulmonar primária manifestada inicialmente como consolidação lobar. RESULTADOS: O padrão radiológico mais frequente foi a consolidação lobar com calcificações, escavações e áreas de necrose de permeio, associada a abaulamento da cissura. Sinais de disseminação broncogênica e linfadenomegalia foram observados em todas elas. Consolidação de aspecto pseudotumoral, com efeito de massa, foi observada em um caso. CONCLUSÃO: Nos casos estudados observou-se que a tuberculose pulmonar primária manifestada como consolidação lobar apresenta imagens características à tomografia computadorizada, como escavações, áreas hipodensas e calcificações de permeio à consolidação. A associação com linfonodomegalias com centro necrótico e sinais de disseminação broncogênica reforçam o diagnóstico de tuberculose.

Objective:Rare disease Background:Granulosa cell tumor of the ovary is very rare in childhood; its most common clinical manifestation is isosexual precocious puberty. Clinical presentation as acute abdomen due to pain and ovarian torsion is rare, but a granulosa cell tumor must be suspected in a patient with this acute presentation and signs of early puberty. Adult-type granulosa cell tumor is an even rarer occurrence in children. Case Report:We report a case of torsion of adult-type granulosa cell tumor of the ovary in a 5-year-old patient with acute abdominal pain and ovarian torsion and highlight the importance of histological diagnosis of this tumor for the therapeutic plan and progression of these patients. Conclusion:Precocious puberty, pain, abdominal distension, and an ultrasonography with suspicion of ovarian torsion are warning signs that may indicate the presence of a gonadal stromal tumor in pediatric patients seen at an emergency unit. These patients require long-term follow-up by a pediatrician and gynecologist because of the potential for late recurrence.
