Non-traumatic uriniferous pseudocyst. Report of a case

Area of Science:

• Uropathology
• Oncology
• Surgical Pathology

Background:

• Urothelial carcinoma is a significant malignancy affecting the urinary tract.
• Uriniferous pseudocysts are rare, typically associated with trauma or surgical complications.
• Autopsy provides a unique opportunity to study rare pathological findings.

Observation:

• An incidentally discovered non-traumatic uriniferous pseudocyst was identified during autopsy.
• The patient had invasive urothelial carcinoma involving the ureteral orifices.
• Massive paraaortic lymph node metastasis from the urothelial carcinoma was present.

Findings:

• The uriniferous pseudocyst formation is attributed to ureteral obstruction secondary to metastatic urothelial carcinoma.
• Paraaortic lymphadenopathy likely contributed to the obstruction and subsequent pseudocyst development.
• This case highlights an unusual complication of advanced urothelial carcinoma.

Implications:

• Understanding the mechanism of pseudocyst formation in malignancy is crucial for diagnosis and management.
• This finding expands the spectrum of complications associated with invasive urothelial carcinoma.
• Further investigation into the pathogenesis of non-traumatic uriniferous pseudocysts is warranted.
