Clinical and histological features and outcome of primary malignant lymphomas of the bladder

Age/SexClinical historyHistological diagnosisImmunophenotypeFollow up
F, female; M, male; MALT, mucosa associated lymphoid tissue.
66/FLarge bladder mass that clinically resembled stage T3 transitional cell carcinoma. No lymphadenopathy on physical examination or computed tomographyLow grade MALT-type lymphomaCD20+Alive after 1 year
79/FHaematuria. Multiple bladder tumours on cystoscopy. No evidence of tumour elsewhereLow grade MALT-type lymphomaCD20+No follow up
59/FFirst diagnosed in 1995. Defaulted follow up. Re-presented 1998. Solid necrotic tumour anterior wall of bladder, clinically stage T2–T3Low grade MALT-type lymphomaCD20+ CD43+Alive with disease after 3 years
84/FPresented with intermittent haematuria over the previous 2 years. Cystoscopy showed mucosal congestion but no obvious tumour. Repeat cystoscopy 3 weeks later showed tumour obscuring the right ureteric orifice, clinically stage T3. There was no lymphadenopathy and no evidence of tumour elsewhere. Macroscopically thought to be invasive transitional cell carcinomaDiffuse large B cell lymphomaCD20+Died of disease after 6 months
67/MPainless haematuria. Irregular tumour mass in right side of bladder. Treated with radiotherapy and chemotherapy. Now has recurrent solid growth in posterior wall of bladder. No evidence of disease elsewhereDiffuse large B cell lymphomaCD20+ CD30+Alive with disease after 16 years
80/FPresented with a 3 month history of intermittent haematuria. Impaired renal function. Cystoscopy showed a ring of tumour obstructing the right urethral meatus. Treated with radiotherapy. Bone marrow uninvolved. No evidence of lymphadenopathy or tumour elsewhereDiffuse large B cell lymphomaCD20+Alive and well after 3 years 8 months
