RESUMO

INTRODUCTION: Involvement of the peritoneum occurs very rarely and is exceptional as an exclusive extranodal presentation of lymphomas. In most cases lymphomas associated with this rare entity are high-grade ones. PL secondary to high-grade nodal lymphoma is more frequent than primary peritoneal lymphoma, and there are only a few cases of the latter described in the literature. DESCRIPTION OF THE CASE: We present the case of a patient with constitutional syndrome and imaging findings suggestive of peritoneal carcinomatosis who was finally diagnosed with a Diffuse Large B-cell Lymphoma (DLBCL) by an ultrasound-guided core needle biopsy (CNB) of peritoneum. The patient received one polychemotherapy cycle; however tumor lysis syndrome occurred with death of the patient in the following days. This case tries to show the existence of a PL without other radiological findings of lymphoma, a fact that is very exceptionally described in the literature. DISCUSSION: The differential diagnosis between PL and others peritoneum diseases such as peritoneal carcinomatosis, malignant primary peritoneal mesotheliomas, tuberculous peritonitis, sarcomatosis, diffuse peritoneal leiomyomatosis or benign splenosis, constitutes a major problem in imaging techniques. An exhaustive analysis of the radiological characteristics as well as a clinical-analytical context allows the differential diagnosis against peritoneal carcinomatosis and the rest of the entities previously referred although the final diagnosis will always be a biopsy. CONCLUSION: PL usually manifests as an aggressive histological subtype of high-grade lymphomas leading to a rapid progression and deterioration of the patient. It is crucial for the radiologist and the clinician to be aware of this rare entity providing the earliest possible diagnosis and optimal treatment to prolong the patient's life.

RESUMO

Rivaroxaban is a once-daily oral anticoagulant currently indicated for the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation. It is also indicated for the prevention and treatment of venous or pulmonary thromboembolism. Despite the known advantages of rivaroxaban over standard therapy, this treatment is not exempt from bleeding. We present the case of a 51-year-old woman with arterial hypertension and paroxysmal atrial fibrillation anticoagulated with rivaroxaban 20 mg o.d. Patient was admitted to the emergency department because of intense abdominal pain, high temperature, hypotension, tachycardia and a big tumor in the right abdominal area. The ultrasonic exam showed a big collection in the thoracic and abdominal area, compatible with hematoma. Due to clinical instability, urgent surgery was required. Based on the results of coagulation parameters (PT: 17.5 s), the time from the last rivaroxaban dose was taken, and the patient weight, nonactivated prothrombin complex concentrate at a single dose of 1000 IU was administrated intravenously 1 h before the surgery. PT value decreased to normal value (13.5 s), and surgery was performed without any bleeding complication. The management of patients treated with rivaroxaban who require urgent surgery is discussed in this report.
