RESUMO
Burkitt lymphoma is a non-Hodgkin B-cell lymphoma with a high prevalence in the pediatric population. Abdominal manifestations are well known in sporadic Burkitt lymphoma and vary from nonspecific symptoms to intestinal obstruction due to intussusception; however, mass-like splenic involvement has been scarcely described. OBJECTIVE: To present a case of a patient with a splenic mass whose histopathological analysis revealed Burkitt lymphoma. CLINICAL CASE: A 13-year-old female patient presented with abdominal pain, progressive weight loss, and fever. Imaging studies showed a splenic mass, intestinal thickening, and ileal intussusception. Histopathological analysis of spleen biopsy revealed Burkitt lymphoma. After the first cycle of chemotherapy (BFM95-NHL protocol), abdominal symptoms resolved; no other signs suggestive of intussusception were observed, as well as a significant reduction of the splenic mass was observed. CONCLUSIONS: Burkitt lymphoma in pediatric patients can present as a well-defined splenic tumor, causing no splenomegaly. In addition, its management does not require surgery since it can be resolved with chemotherapy.

Introducción: Se conoce poco de la forma adquirida del déficit del factor VII y son pocos los casos reportados en la literatura. Objetivo: Presentar el caso de una paciente con déficit aislado del factor VII, en el contexto de una hemorragia digestiva baja. Presentación del caso: Mujer peruana de 82 años que acude a emergencia por presentar hemorragia digestiva baja. Durante los exámenes de rutina se le detecta tiempo de protrombina prolongado y déficit aislado de factor VII. No se evidencia mecanismos patológicos de deficiencia de vitamina K o malabsorción, terapia anticoagulante con antagonistas de la vitamina K, hiperfibrinolisis o coagulación intravascular diseminada. Respondió al tratamiento con plasma fresco congelado y los resultados normales de la prueba hematológica realizada a la hermana, alejan la posible etiología hereditaria. Conclusión: Este caso peruano de déficit aislado del factor VII, en el contexto de una hemorragia digestiva baja, permite sumar información a la escasa evidencia Latinoamericana(AU)
Introduction: Little is known about the acquired form of factor VII deficiency and few cases are reported in the literature. Objective: To present a case of a patient with an isolated deficit of factor VII, in the context of low gastrointestinal bleeding. Presentation of the case: 82-year-old Peruvian woman who comes to the emergency room for presenting with lower GI bleeding. Prolonged prothrombin time and isolated factor VII deficiency are detected during routine examinations. There were no evidence of pathological mechanisms of vitamin K deficiency or malabsorption, anticoagulant therapy with vitamin K antagonists, hyperfibrinolysis, or disseminated intravascular coagulation. She responded to the treatment with fresh frozen plasma and the normal results of the hematological test carried out on the sister remove the possible hereditary etiology. Conclusion: This Peruvian case of isolated factor VII deficit, in the context of low gastrointestinal bleeding, allows adding information to the limited Latin American evidence(AU)
