Summary
This report details the first documented case of Cronkhite-Canada syndrome associated with esophageal, gastric, and lung cancer in a 69-year-old man. The patient presented with gastrointestinal polyps, characteristic symptoms, and multiple malignancies.
Area of Science:
- Gastroenterology
- Oncology
- Clinical Case Study
Background:
- Cronkhite-Canada syndrome is a rare non-neoplastic disorder characterized by gastrointestinal polyposis, ectodermal abnormalities, and protein-losing enteropathy.
- While gastrointestinal cancers have been reported in conjunction with Cronkhite-Canada syndrome, the association with lung cancer is unprecedented.
Observation:
- A 69-year-old man presented with classic Cronkhite-Canada syndrome symptoms including diarrhea, weight loss, nail shedding, and widespread gastrointestinal polyps.
- Initial treatment with prednisone led to symptom improvement, but subsequent investigations revealed superficial esophageal and gastric cancers.
- A year later, the patient was diagnosed with small and large cell lung carcinoma.
Findings:
- Histopathological examination confirmed moderately-differentiated squamous cell carcinoma of the esophagus and well-differentiated tubular adenocarcinoma of the stomach.
- The lung tumor was diagnosed as undifferentiated carcinoma, small and large cell type.
- This case represents the first instance of Cronkhite-Canada syndrome co-occurring with esophageal, gastric, and lung malignancies.
Implications:
- This unique case expands the known oncological associations of Cronkhite-Canada syndrome.
- It highlights the importance of vigilant cancer screening in patients diagnosed with this rare syndrome.
- Further research may elucidate potential sharedPathways or risk factors between Cronkhite-Canada syndrome and multiple primary cancers.
