# Safety and Efficacy of Endoscopic Ultrasound-Guided Fine-Needle Aspiration Biopsy of Littoral Cell Angioma

## TL;DR

A new method using endoscopic ultrasound-guided biopsy successfully diagnosed a rare spleen tumor, offering a safer alternative to traditional methods.

## Contribution

Demonstrates the successful use of EUS-FNAB for diagnosing Littoral Cell Angioma, a novel diagnostic approach.

## Key findings

- EUS-FNAB successfully diagnosed Littoral Cell Angioma with minimal complications.
- The method offers a safer alternative to splenectomy or percutaneous biopsy for rare vascular tumors.
- Encourages further exploration of EUS-FNAB for diagnosing similar splenic lesions.

## Abstract

Littoral cell angioma (LCA) is a rare vascular tumor of the spleen that often requires histopathological analysis for diagnosis due to non-specific imaging features. The current approach is either splenectomy or image-guided percutaneous biopsy which carries notable procedure-associated morbidity and limited accuracy. We present a novel case of LCA successfully diagnosed with endoscopic ultrasound fine-needle aspiration biopsy (EUS-FNAB), demonstrating its potential to reduce the morbidity associated with traditional percutaneous biopsy methods. This case highlights EUS-FNAB's advantage in minimizing complications and its effectiveness in diagnosing vascular tumors of the spleen, supporting its inclusion in the diagnostic algorithm for splenic lesions. Further cases are encouraged to explore EUS-FNAB's role in diagnosing rare vascular tumors such as LCA to establish its efficacy and safety profile.
