title: [A rare cause of bladder neck obstruction: cervico-trigonal cysts. Report of 2 clinical cases].
abstract: Two rare cases of cervico-urethral obstructive lesions are described, illustrating two typical examples of the twofold pathogenic possibilities of the affection. The first patient had a probably congenital cervico-trigonal cyst due to a ureteral bud in the bladder wall. The second case presented different symptoms and signs, and this together with histology findings suggested an acquired nature of the lesion from cystic transformation of an infected glandular structure. The published literature is reviewed and diagnostic difficulties are emphasized, particularly differentiation from a prostate median lobe lesion.
