Summary
This case study highlights renal cystic adenocarcinoma, a rare kidney cancer. High intracystic lactate dehydrogenase (LDH) levels were key to diagnosis when imaging was unclear.
Area of Science:
- Nephrology
- Oncology
- Radiology
Background:
- Renal cystic adenocarcinoma is a rare malignant kidney tumor.
- Distinguishing cystic renal masses from benign cysts can be challenging.
- Early and accurate diagnosis is crucial for patient outcomes.
Observation:
- A case of renal cystic adenocarcinoma presented as a large cystic mass.
- The mass did not meet the criteria for a simple renal cyst.
- Elevated intracystic lactate dehydrogenase (LDH) levels were observed.
Findings:
- High intracystic LDH levels aided in achieving a definitive diagnosis.
- Radiological imaging provided valuable diagnostic information.
- Negative cytology results had limited diagnostic value in this case.
Implications:
- This case underscores the importance of considering malignancy in complex cystic renal masses.
- Intracystic LDH measurement can be a critical diagnostic biomarker.
- Radiological assessment combined with biochemical markers improves diagnostic certainty for challenging renal lesions.
