Diagnosis of extracavitary primary effusion lymphoma by urine cytology

摘要

A 46-year-old man with HIV, not on HAART (highly active anti-retroviral therapy), presented with abdominal pain and urinary retention. A large, suprapubic mass and inguinal lymphadenopathy was palpated on examination. Laboratory data showed renal failure, hyperuricemia, anemia, and thrombocytopenia. CT scans showed bilateral hydronephrosis caused by a pelvic mass involving the bladder with caudal extension encasing the ureters bilaterally. There was diffuse retroperitonal, abdominal, and pelvic lymphadenopathy.
