ABSTRACT

Mucormycosis is an uncommon fungal infection caused by Mucorales. It frequently occurs in patients with neutropenia, diabetes, malignancy and on corticoid therapy. However, it is rare in patients with AIDS. Clinical disease can be manifested in several forms. The case reported illustrates the rare occurrence of chromoblastomycosis and mucormycosis in an immunosuppressed patient with multibacillary leprosy, under prolonged corticosteroid and thalidomide therapy to control leprosy type 2 reaction. Neutrophil dysfunction, thalidomide therapy and work activities are some of the risk factors in this case. Chromoblastomycosis was treated by surgical excision and mucormycosis with amphotericin B. Although the prognosis of mucormycosis is generally poor, in the reported case the patient recovered successfully. This case should alert dermatologists to possible opportunistic infections in immunosuppressed patients.


Mucormicose é uma infecção fúngica incomum causada por Mucorales. Ocorre frequentemente em pacientes com neutropenia, diabetes, corticoterapia e condições malignas. Porém, é rara em pacientes com AIDS. A doença pode apresentar-se em diferentes formas. Este caso ilustra a rara ocorrência de mucormicose e cromoblastomicose em um paciente com hanseníase multibacilar, que estava sendo tratado com prednisona e talidomida devido a eritema nodoso (reação hansênica tipo II). Disfunção de neutrófilos, uso de talidomida e atividades profissionais são alguns fatores de risco neste caso. A cromoblastomicose foi tratada por excisão cirúrgica e a mucormicose com anfotericina B. Embora o prognóstico da mucormicose seja ruim, neste caso o tratamento foi bem sucedido. Este caso alerta dermatologistas para a possibilidade de infecções oportunistas em pacientes imunossuprimidos.

ABSTRACT

Mucormycosis is an increasingly emerging life-threatening infection and is an important cause of morbidity and mortality in patients with leukemia. We present the case of a 4-year-old boy with an acute lymphoblastic leukemia complicated by severe and prolonged neutropenia during induction chemotherapy, who developed cutaneous mucormycosis of the elbow. Direct microscopy with KOH and the histopathologic observation of the skin revealed fungal hyphae without septations. The cultures were positive for Rhizopus microsporus var oligosporus. The patient was treated succefully with amphotericin B during 40 days, surgical debridement and dermoepidermic graft. Early recognition and prompt intervention with combined medical and surgical treatment may improve the outcome. The most common management strategy in survivors involves a combination of antifungal therapy with amphotericin B and surgical debridement.


La mucormicosis es una enfermedad emergente grave, producida por hongos saprófitos del orden Mucorales, que afecta fundamentalmente a pacientes inmunocom-prometidos. La forma cutánea se origina por inoculación de esporas dentro de la dermis con el subsecuente desarrollo de una lesión tipo ectima, generalmente única y de evolución rápidamente progresiva, por las características angioinvasoras del hongo, que determina amplias zonas de infartos y necrosis en los tejidos. Presentamos el caso de un paciente con cuatro años de edad, con diagnóstico de leucemia linfoblástica aguda, en quimioterapia de inducción, que cursó con neutropenia profunda y prolongada, presentando una lesión cutánea en el codo compatible con ectima gangrenoso. Recibió tratamiento antimicrobiano y antifúngico, asociado a un aseo quirúrgico. El cultivo para hongos demostró crecimiento de Rhizopus microsporus var oligosporus, y la histología concluyó presencia de hifas no septadas. El estudio de extensión descartó compromiso óseo, sinusal y cerebral. Completó 40 días de terapia antifúngica con anfotericina B deoxicolato, evolucionando satisfactoriamente. Posteriormente requirió injerto dermo-epidérmico. Si bien esta patología es infrecuente, debemos sospecharla en pacientes con neoplasias hematológicas, para establecer un diagnóstico etiológico oportuno, ya que el tratamiento contempla el desbridamiento quirúrgico precoz asociado a antifúngicos sistémicos, siendo de elección anfotericina B.

ABSTRACT

A mucormicose é uma infecção fúngica oportunista, habitualmente fulminante, que acomete, principalmente, imunodeprimidos. Pode apresentar-se sob as formas rinocerebral, pulmonar, gastrintestinal, cerebral, cutânea, subcutânea e disseminada. O diagnóstico é estabelecido a partir da biopsia de tecido com envio de material para cultura de fungos, podendo-se usar exames de imagem para quantificar a área acometida. O tratamento é cirúrgico, devendo ser associado à anfotericina B.


Murcomicosis is a fungal opportunistic infection that is usually fatal, which attacks, essentially, immunodeficient people. It usually presents itself in: rinocerebral, pulmonary, gastrointestinal, cerebral, cutaneous, subcutaneous and disseminated forms. The diagnosis is established by tissue biopsy after fungal culture, and image exams. Can be used to calculate the surgical treatment should be associated with anfotericin B.
