Table 1

Clinicopathologic characteristics of plasmacytoid urothelial carcinomas.

Case	Age/sex	Presenting symptoms	Operation	TNM stage	Plasmacytoid component	Other components	Follow-up status
1	64/M	Hematuria	TUR	IV	30%	CONV	LOF,; after 16 mo
2	83/M	Hematuria	RC	IV	80%	CONV, MP	DOD,; 28 mo
3	69/M	Urgency	RC	III	80%	CONV	DOD,; 10 mo
4	73/M	Hematuria	RC	IV	100%	None	LOF,; after 3 mo
5	57/M	Hematuria	RC	IV	100%	None	AWD,; 19 mo
6	82/F	Hematuria	TUR	I	70%	CONV	AWD,; 1 mo

AWD indicates alive with disease; CONV, conventional type; DOD, died of disease; F, female; LOF, loss of follow-up; M, male; MP, micropapillary type; RC, radical cystectomy; TUR, transurethral resection.
