Summary
A kidney cyst with neoplastic degeneration was discovered incidentally. Surgical removal led to a papillary adenoma diagnosis, with no recurrence observed nine years later.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Incidental detection of an abnormal chest shadow in a 57-year-old male during a routine medical examination.
- Further investigation revealed a left posterior mediastinal tumor (neurinoma) and a separate right kidney mass.
Observation:
- The right kidney mass was a clearly demarcated, homogenous lesion measuring 16 x 12 mm with a CT value of 79 HU.
- The lesion's content was sticky and blackish-green, with visible neoplastic degenerations (8x4 mm and 5x5 mm) within the cyst.
Findings:
- The patient underwent a partial nephrectomy, excising the cystic section of the kidney mass.
- Pathological diagnosis confirmed the presence of papillary adenoma.
Implications:
- This case highlights the importance of thorough investigation of incidental findings.
- Successful surgical management of renal papillary adenoma with cystic degeneration, demonstrating long-term positive patient outcomes.
