Microcytic normochromic anemia associated with iron storage by hypernephroma
American Journal of Clinical Pathology
|December 1, 1978
Summary
Renal cell carcinoma in a 38-year-old female patient was linked to iron-deficiency anemia. Tumor cells stored iron, causing anemia recurrence with metastasis, suggesting a metabolic diversion of iron by cancer cells.
Area of Science:
- Oncology
- Hematology
- Medical Biochemistry
Background:
- A 38-year-old female presented with microcytic normochromic anemia and renal cell carcinoma.
- The patient underwent resection of the renal cell carcinoma.
Observation:
- Anemia temporarily resolved with ferrous gluconate treatment.
- Anemia recurred with the development of abdominal lymph node metastases.
- Hemosiderin deposits were identified within tumor cells in both the primary kidney tumor and metastases.
Findings:
- Tumor cells demonstrated significant iron sequestration.
- Metabolic diversion and storage of iron by renal cell carcinoma cells is postulated as the cause of anemia.
Implications:
- This case highlights a potential mechanism linking renal cell carcinoma to anemia through iron dysregulation.
- Understanding tumor iron metabolism may offer novel therapeutic targets for managing cancer-associated anemia.
