Summary
Esophageal leiomyomatosis, a rare condition, was diagnosed in a man presenting with a rare pedunculated esophageal tumor. Endoscopic ultrasonography (EUS) aided in identifying this rare leiomyoma presentation.
Area of Science:
- Gastroenterology
- Pathology
- Radiology
Background:
- Esophageal leiomyomas are common benign tumors, but diffuse esophageal leiomyomatosis is rare.
- Pedunculated leiomyomas of the esophagus are exceptionally uncommon presentations.
Observation:
- A 61-year-old man incidentally found to have an esophageal tumor via chest CT scan.
- Endoscopy revealed a pedunculated polyp with normal mucosa and surrounding submucosal elevation.
- Endoscopic ultrasonography (EUS) showed a 3 cm hypoechoic tumor originating from the muscularis mucosa and muscularis propria.
Findings:
- Pathological diagnosis confirmed leiomyoma for both the polyp and surrounding submucosal lesions.
- Diffuse esophageal leiomyomatosis was suspected due to the characteristic pathological distribution.
- EUS findings were consistent with previously reported features of diffuse esophageal leiomyomatosis.
Implications:
- Accurate diagnosis of rare esophageal leiomyomatosis can be challenging.
- EUS is a valuable tool in diagnosing diffuse esophageal leiomyomatosis.
- This case highlights the importance of integrating imaging and pathological findings for rare tumor diagnoses.
