This case underscores the importance of multidisciplinary evaluation in diagnosing subepithelial lesions, as initial techniques may lead to misdiagnosis.

this study against the rest of the selank corpusSummary and findings
This case report discusses a duodenal subepithelial lesion misdiagnosed as a benign hemangioma, which was later confirmed to be a gastrointestinal stromal tumor (GIST) following further evaluation. The initial diagnosis was made using a bite-on-bite biopsy technique. The report emphasizes the need for multidisciplinary review in managing such cases.
Abstract
Gastrointestinal stromal tumors (GISTs) are rare, potentially malignant mesenchymal neoplasms that can arise anywhere within the gastrointestinal tract or abdominal cavity. We present a case of an incidentally discovered duodenal subepithelial lesion that was initially endoscopically sampled using bite-on-bite biopsy technique and misdiagnosed as a benign hemangioma. Following multidisciplinary review, the patient underwent endoscopic ultrasound with fine-needle aspiration and fine-needle biopsy, which ultimately confirmed the diagnosis of GIST. This case highlights the limitations of the bite-on-bite technique for diagnosing subepithelial lesions and underscores the importance of multidisciplinary evaluation when managing potentially high-risk subepithelial lesions.
Background
Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms that can occur in the gastrointestinal tract. Previous literature has documented challenges in accurately diagnosing subepithelial lesions. This case report is significant as it illustrates the potential pitfalls of the bite-on-bite biopsy technique in diagnosing such lesions.
Methods
The report describes a case involving a duodenal subepithelial lesion initially sampled using the bite-on-bite biopsy technique. Following misdiagnosis, a multidisciplinary review led to endoscopic ultrasound and fine-needle aspiration to confirm the diagnosis. Specific details on sample size and duration are not provided.
Results
The initial bite-on-bite biopsy misidentified the lesion as a benign hemangioma. Subsequent fine-needle aspiration and biopsy confirmed the lesion as a gastrointestinal stromal tumor (GIST). Exact numeric findings and statistical analyses are not reported.
Interpretation
This case aligns with existing literature that highlights diagnostic challenges in subepithelial lesions. The misdiagnosis underscores the need for careful evaluation and the potential limitations of certain biopsy techniques. The findings suggest that reliance on bite-on-bite biopsy may lead to significant diagnostic errors.
Key findings
- Incidentally discovered duodenal subepithelial lesion misdiagnosed as benign hemangioma.
- Diagnosis of GIST confirmed after endoscopic ultrasound with fine-needle aspiration and fine-needle biopsy.
Limitations
- Not a clinical trial, case report only.
- No numeric data or statistical analysis provided.
- Single case report limits generalizability.
