Myxoid fibroepithelial polyp in caliceal diverticulum

Area of Science:

• Urology
• Pathology
• Nephrology

Background:

• Pyelocaliceal diverticula are rare congenital anomalies of the kidney.
• These structures can harbor various pathologies, including tumors and infections.

Observation:

• A myxoid fibroepithelial polyp was identified within a pyelocaliceal diverticulum in a 58-year-old female patient.
• The polyp was incidentally discovered during diagnostic imaging.

Findings:

• This represents the first documented instance of a myxoid fibroepithelial polyp occurring in a pyelocaliceal diverticulum.
• Histopathological examination confirmed the benign nature of the lesion.

Implications:

• This case expands the known spectrum of potential lesions within pyelocaliceal diverticula.
• Awareness of this rare association may aid in the accurate diagnosis and management of similar future cases.
