Abstract

Urachal carcinoma is a rare tumor that most commonly occurs in ovaries and less often in the adnexal region and urinary system. We herein present two cases of urachal carcinoma: One case was a 32-year-old male patient who presented with painless hematuria with blood clots for 1 month, whereas the other case was a 50-year-old woman who presented with gross hematuria with mild dysuria, urgency and frequent urination for 1 year. Following surgical resection, the two patients were diagnosed with urachal adenocarcinoma (mixed type) and urachal mucinous adenocarcinoma, respectively, based on the histopathological examination. A review of previously published cases and relevant literature is also presented. The aim of the present study was to help understand this disease better, in order to reduce the rate of clinical and pathological misdiagnosis.
