RESUMO

Background: Mucormycosis is a rare infection caused by ubiquitous fungi of the Mucorales order that mainly affects immunocompromised patients. These fungi have an important tropism for blood vessels that allows them to spread rapidly and cause thromboembolic events. Case report: We present a case of an 8-year-old male patient diagnosed with acute lymphoblastic leukemia treated with chemotherapy. He presented icteric syndrome, hepato-splenomegaly, and data of intestinal obstruction. Although he underwent intestinal resection, he did not improve and died. The autopsy identified disseminated mucormycosis involving the brain, lungs, esophagus, small intestine, colon, and pancreas. Conclusions: Hematological neoplastic diseases and their treatment are important risk factors for developing infections by opportunistic microorganisms such as mucormycosis. Early diagnosis and adequate treatment are essential due to their intrinsic difficulty and the high mortality rate of these cases.


Introducción: La mucormicosis es una infección poco frecuente causada por hongos ubicuos del orden de los Mucorales que afecta principalmente a pacientes inmunocomprometidos. Estos hongos poseen un importante tropismo por vasos sanguíneos que les permite diseminarse rápidamente y provocar lesiones trombo-embólicas. Caso clínico: Se presenta el caso de un paciente de sexo masculino de 8 años con diagnóstico de leucemia linfoblástica aguda tratada con quimioterapia. Presentó síndrome ictérico, hepato esplenomegalia y datos de obstrucción intestinal. A pesar de que fue sometido a resección intestinal, no presentó mejoría y falleció. En la autopsia se identificó mucormicosis diseminada con afección de cerebro, pulmones, esófago, intestino delgado, colon y páncreas. Conclusiones: Las enfermedades neoplásicas hematológicas y su tratamiento son importantes factores de riesgo para el desarrollo de infecciones por microorganismos oportunistas como la mucormicosis. El diagnóstico temprano y adecuado tratamiento son importantes debido a la dificultad intrínseca de los mismos y la alta tasa de mortalidad de estos casos.

RESUMO

A 29-year-old woman presented with a breast tumor with a primary diagnosis of MALT lymphoma. A repeat biopsy revealed a hematological neoplasm with diffuse, Indian file, and targetoid patterns. The cells were intermediate size with eosinophilic granules; the immunophenotyping showed monocytic differentiation, and no lymphoepithelial lesion was observed. The diagnosis was granulocytic sarcoma. Three different bone marrow biopsies were negative for neoplastic infiltration. After treatment, she developed secondary pancytopenia which contributed to her death 16 months after primary diagnosis. Granulocytic sarcoma of the breast is uncommon. A complete panel of immunohistochemistry is necessary to perform this diagnosis.
