RESUMO
Müllerian duct cysts result from an abnormality in regression of the Müllerian system. They may occasionally give rise to symptoms. We report an unusual case of acute urinary retention in an old man caused by a giant Müllerian duct cyst. A 77-year-old man presented with of acute urinary retention. After bladder drainage, digital rectal examination found a large soft supraprostatic mass. Transrectal ultrasound and computed tomography scans revealed a large multilocular retrovesical cystic mass. The patient underwent open surgical resection of the cyst. Histologically, the cystic lesion was lined with stratified cubocolumnar cells, consistent with a Müllerian duct cyst. Acute urinary retention in the elderly is not always related to prostatic diseases. Other causes, even congenital ones, may be involved.
RESUMO
CONTEXT: Clear cell adenocarcinoma of the urethra is an extremely rare tumour. Its histogenetic derivation remains controversial. CASE REPORT: We report a new case of clear cell adenocarcinoma of the proximal urethra in a 56-year-old woman who presented with grossly hematuria. Urethral cystoscopy revealed a tumour protruding from the posterior urethral wall at the bladder neck. Treatment consisted of urethrocystectomy with pelvic lymph node dissection. Histologically, the neoplasm consisted of clear cell adenocarcinoma of the urethra. CONCLUSION: It appears that female urethral adenocarcinoma has more than one tissue of origin.
RESUMO
Primary large-cell neuro-endocrine carcinoma of the bladder is a rare aggressive tumour with a very poor prognosis. The authors report the case of 78-year-old male patient with primary large-cell neuro-endocrine carcinoma of the bladder and discuss the pathological and therapeutic aspects of this tumour in the light of a review of the literature.
