Urinary Frequency as a Presentation of Bulky Malignant Lymphoma in the Pelvis

Abstract EN

Malignant lymphomas may originate from any area of the body and cause a variety of symptoms.

However, a malignant lymphoma causing urinary symptoms is uncommon.

We report a unique case of a 77-year-old woman who presented with a persistent pollakiuria.

Radiographic imaging showed a large pelvic mass (13×13×11 cm) remarkably compressing and invading the bladder wall and accompanied with bilateral hydronephrosis.

Urinary cytology revealed malignant lymphoma, and a final diagnosis of malignant lymphoma was made on the basis of transvaginal needle biopsy.

Urinary cytology facilitated the definite diagnosis, following which we initiated a rapid and successful treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone with rituximab.
