We reported a case of primary renal lymphoma (PRL) presented with non-oliguric acute kidney injury and bilateral kidney infiltrates in an individual with human immunodeficiency virus (HIV) disease. Acute kidney injury secondary to lymphoma infiltrates is very rare (less than 1% of hematological malignancy). A 37-year-old gentleman with underlying human immunodeficiency virus (HIV) disease was on combined antiretroviral therapy since diagnosis. He presented to our center with uremic symptoms and gross hematuria. Clinically, bilateral kidneys massively enlarged and were ballotable. Blood investigations showed hemoglobin of 3.7 g/L, urea of 65.6 mmol/L, and serum creatinine of 1630 µmol/L with hyperkalemia and metabolic acidosis. An urgent hemodialysis was initiated, and he was dependent on regular hemodialysis subsequently. Computed tomography renal scan showed diffuse nonenhancing hypodense lesion in both renal parenchyma. Diagnosis of diffuse large B cell lymphoma with germinal cent...

Peripheral T-Cell lymphomas (PTCL) are relatively rare diseases but appear to be highly aggressive and display worse remission and survival rates than B-cell lymphomas. Despite unsatisfactory results with the cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) regimen, it remains the reference front-line therapy in these diseases, but has not been challenged in phase III trials. The Groupe Ouest Est d’Etude des Leucémies et Autres Maladies du Sang (GOELAMS) devised an alternative therapeutic schedule including etoposide, ifosfamide, cisplatin alternating with doxorubicin, bleomycin, vinblastine, dacarbazine (VIP-reinforced-ABVD; VIP-rABVD) and compared it to CHOP/21 as front-line treatment in non-cutaneous PTCL. All newly diagnosed patients were eligible. The primary objective was to improve the 2-year event-free survival (EFS) rate. Secondary objectives were to compare the response rate, overall survival, and toxicities as well as identify prognostic factors. Eighty-eight patients were identified between 1996 and 2002. Both arms were well balanced for patients’ characteristics in terms of histological and clinical presentation. No significant difference was observed between the two arms in terms of 2-year EFS. Anaplastic large cell lymphoma type and Ann Arbor stage I–II were identified as two independent favourable prognostic factors influencing survival. VIP-rABVD was not superior to CHOP/21 in terms of EFS as first-line treatment of PTCL, confirming that CHOP/21 remains the reference regimen in these lymphomas.

Lymphomatoïd granulomatosis is a rare lymphoproliferative disease caused by Epstein-Barr virus described in 1972 by Liebow. The most common primary localization is the lungs. Other systems are affected occasionally such as the skin, central nervous system, renal and gastrointestinal system. Some cases have been described at the laryngeal level in immunosuppressed patients. This is a case report of supraglottic lymphomatoid granulomatosis in an immunocompetent patient. A literature review on lymphomatoid granulomatosis will be detailed and the clinical case will be described including investigations, treatment and follow-up. The differential diagnosis of this pathology as well as the importance of histopathology will also be discussed. Several radiological imaging and histopathology slides will be presented. Emphasis will be placed on the difficulty of diagnosis given the frequent multisystem involvement and on the importance of the multidisciplinary team approach including otolaryn...
