Abstract
Lymphomas are one of the most common malignant entries across all populations. Originating most commonly from the lymph nodes, extranodal lymphomas, including those originating from the connective tissue capsule of the internal organs, are rare entries. Herein we present a case report of a 78-year-old male patient presenting with a palpable mass in the region of the left kidney. Ultrasound and computer tomography revealed a mass engulfing the kidney. Nephrectomy was performed, with the histopathological investigation revealing a non-Hodgkin lymphoma originating from the renal capsule, with infiltration into the adjacent tissues. The patient was referred to a hematologist for treatment and one and a half years later, following two negative bone marrow biopsies, the patient is alive and disease-free.
