Because diagnosis of urethral diverticulum is often elusive the presence of a tumor within the diverticular cavity may be overlooked until it has grown beyond the confines of the diverticulum. A search of the medical records from 1940 to 1975 at the University of California Medical Center in San Francisco and Alta Bates Hospital in Berkeley has revealed only 3 cases of carcinoma within a urethral diverticulum. Two are presented here and the third was reported by Hinman in 1960. The paucity of cases in the literature reflects the rarity of such location for the tumor--or, perhaps, rather its evasive diagnostic nature. Undoubtedly, many cases are unreported but the important message for the clinician is that he suspect a urethral diverticulum (with the possibility of underlying neoplasm) in any patient with unexplained persistent irritative symptoms of the lower genitourinary tract.
由于尿道憩室的诊断常常难以捉摸，憩室内肿瘤的存在可能会被忽视，直到其生长超出憩室范围。对旧金山加利福尼亚大学医学中心和伯克利阿尔塔贝茨医院1940年至1975年的病历进行检索后发现，尿道憩室内癌仅有3例。这里介绍其中2例，第3例由欣曼于1960年报道。文献中病例稀少反映出该部位肿瘤罕见——或者说，更可能是其诊断隐匿的特性。毫无疑问，许多病例未被报道，但对临床医生来说重要的是，对于任何有无法解释的下泌尿生殖道持续性刺激症状的患者，都要怀疑存在尿道憩室（并有可能存在潜在肿瘤）。
