Summary
Synchronous multiple primary cancers of the stomach and kidney are exceptionally rare. This case highlights a rare occurrence in a 67-year-old female, emphasizing the need for further research into risk factors.
Area of Science:
- Oncology
- Gastroenterology
- Nephrology
Background:
- Synchronous multiple primary cancers involving the stomach and kidney are exceedingly rare, with only 45 cases documented globally by 2020.
- No specific risk factors have been definitively identified for this rare dual cancer presentation.
Observation:
- A 67-year-old female presented with a three-month history of persistent vomiting and abdominal pain.
- Diagnostic workup revealed concurrent gastric and renal malignancies.
Findings:
- Upper endoscopy with biopsies confirmed gastric adenocarcinoma with signet ring cell morphology.
- CT-guided biopsies identified a primary kidney neoplasm, establishing the diagnosis of synchronous multiple primary cancers.
Implications:
- This case contributes to the limited literature on synchronous gastric and kidney cancers.
- Further investigation is warranted to elucidate potential etiological factors and improve diagnostic and therapeutic strategies for this rare condition.
