[ XXXX : two case reports].

@entity1 @entity101 @entity1494 @entity5 @entity150 @entity1823
Case 1. A 48-year-old @entity1 with no history of @entity101 was referred to our hospital with a 1 cm @entity150 . According to cystoscopy, magnetic resonance imaging and 131I-MIBG scintigraphy, we diagnosed it as a @entity1494 . Partial cystectomy was performed. The histological findings supported the diagnosis of @entity1494 . Six years later, he was free of any evidence of recurrence. Case 2. A 64-year-old @entity1 with @entity101 was pointed out to have a 1cm bladder mass by ultrasound in a health examination. She was referred to our hospital for further examination. Cystoscopoy revealed a 1 cm intramural nodule covered by intact urothelium at the right posterior wall. @entity150 was not diagnosed as @entity1823 by cold punch biopsy. So, transurethral resection of the @entity150 was performed for differential diagnosis. The @entity5 was hypervascular and involved the muscular layer of the bladder. Although a transient elevation of blood pressure occurred during the procedure, the @entity5 was resected as completely as possible. The histological diagnosis was @entity1494 . She has been followed up for 27 months after operation without any evidence of recurrence.
