Hemorragia digestiva alta como forma de presentación de hematoma retroperitoneal espontáneo gigante secundario a anticoagulación en una mujer con reordenación del gen JAK2 / Spontaneous retroperitoneal hematoma in a patient under anticoagulant agents presenting as upper gastrointestinal bleeding

Presentamos el caso de una mujer de 44 años de edad con antecedentes de abortos de repetición y síndrome de Budd-Chiari secundario a una mielofibrosis primaria en tratamiento anticoagulante. Consulta por melenas y astenia, presentando anemización progresiva. En una gastroscopia inicial se aprecia una compresión extrínseca a nivel supraampular de segunda porción duodenal, con una úlcera asociada en cara posterior de bulbo y primera rodilla. Posteriormente se diagnostica mediante una tomografía computarizada de un hematoma retroperitoneal espontáneo secundario a anticoagulación. Se trata con drenaje percutáneo y retirada de anticoagulación con buena respuesta inicial. No obstante, presenta complicaciones trombóticas (trombosis subclavia y yugular) y se reintroducen los anticoagulantes con dosis en el límite bajo del rango terapéutico (AU)

We present the case of a 44-year-old woman with past history of repeated miscarriage and Budd-Chiari syndrome secondary to primary myelofibrosis. Because of this she was under treatment with oral anticoagulant agents. The patient was admitted in hospital as she presented with gastrointestinal bleeding (melena), asthenia and progressive anemia. In an initial upper endoscopy an extrinsic duodenal compression associated with an ulcer on the posterior face of the first portion of duodenum and upper duodenal knee was observed. In the following days a huge spontaneous retroperitoneal hematoma due to anticoagulation was diagnosed by computed tomography. This was treated with a percutaneous drainage and withdrawal of the antithrombotic drugs. The evolution of the patient was initially satisfactory but she suffered subclavian and jugular vein thrombosis, and reintroduction of anticoagulant agents at the lowest therapeutic doses was required (AU)

Cristales de sevelamer asociados a lesión de la mucosa del tracto gastrointestinal. Presentación de 2 casos, revisión de la literatura y diagnóstico diferencial morfológico con los cristales de kayexalato / Sevelamer crystals associated with mucosal lesions of the gastrointestinal tract. A report of 2 cases with emphasis on the morphological differential diagnosis with kayexalate crystals and a review of the literature

Sevelamer es un quelante no absorbible del fosfato, usado para tratar la hiperfosfatemia en pacientes con enfermedad renal crónica. La morfología de sevelamer ha sido descrita en un artículo recientemente publicado por Swanson et al., en el que se hace la primera descripción histológica de esta resina en el tracto gastrointestinal. En este artículo informamos de la presencia de cristales de sevelamer asociados a lesión mucosa en 2 pacientes con insuficiencia renal crónica en tratamiento con este fármaco, que presentaron apendicitis aguda perforada con peritonitis el primer caso, y úlceras esofágicas el segundo. Realizamos la descripción histológica de los cristales de sevelamer y hacemos un diagnóstico diferencial morfológico con los cristales de kayexalato, otra resina también usada en pacientes con enfermedad renal crónica (AU)

Sevelamer is a non-absorbable phosphate binder used to treat hyperphosphatemia in patients with chronic renal disease. Sevelamer morphology has been described in a recently published article by Swanson et al., in which the first histological description of this resin in the gastrointestinal tract is made. In this article we report the presence of sevelamer crystals associated with mucosal injury in 2 patients with chronic renal failure treated with this drug; one of them suffered acute perforated appendicitis with peritonitis and other developed oesophageal ulcers. We describe the histology of sevelamer crystals and the morphological differential diagnosis with kayexalate crystals, another resin used in chronic renal disease (AU)
