An unusual pelvic mass: bladder lymphoma

A 58-year-old woman presented to the emergency department after a minor fall, complaining of lower abdominal pain. A large, tender mass arising from the pelvis was palpable, in association with abdominal wall bruising. The patient believed that she may have had a “lump” there for several years. She had had a total abdominal hysterectomy and bilateral salpingo-oopherectomy for benign fibroids three years previously. She denied any gastrointestinal (GI) or genitourinary symptoms. She had no night sweats or weight loss. Routine blood investigations were normal
