Summary
A rare case of primary renal lymphoma (PRL) with localized amyloid deposition was identified in a 78-year-old man. This finding is unique, as no prior reports of PRL with amyloidosis exist.
Area of Science:
- Oncology
- Nephrology
- Pathology
Background:
- Primary renal lymphoma (PRL) is an exceptionally rare condition.
- Diagnosis often occurs incidentally during investigations for other symptoms.
Observation:
- A 78-year-old male presented with hematuria and weight loss.
- Computed tomography revealed a renal tumor during a routine check-up.
Findings:
- Histologic and immunohistochemical analyses confirmed a low-grade lymphoma.
- The tumor exhibited localized amyloid deposition, a feature not previously reported in PRL.
Implications:
- This case expands the known clinicopathological spectrum of primary renal lymphoma.
- Highlights the importance of comprehensive diagnostic evaluation for renal masses.
- Suggests a potential association between PRL and amyloidosis requiring further investigation.
