Waldenström macroglobulinaemia presenting as a perirenal mass: a case report.
Perirenal masses are a rare manifestation of Waldenström macroglobulinaemia (WM). We report a 70-year-old male diagnosed with Waldenström macroglobulinaemia arising as a huge perirenal mass, which was discovered by abdominal ultrasound and computed tomography. The patient underwent ultrasound-guided aspiration biopsy and the histopathological examination showed a monoclonal lymphoplasmocitoid proliferation of B-cells arranged in a diffuse pattern. This case report shows not only the importance of image and biopsy studies, but also the good response to chemotherapy with the CHOP regimen.
