# Pleomorphic Adenoma in a Posterior Cervical Soft Tissue Mass: A Diagnostic Conundrum

## TL;DR

A rare case of pleomorphic adenoma in the neck highlights the challenges in diagnosing soft tissue tumors in this complex region.

## Contribution

This case report documents an extremely rare occurrence of pleomorphic adenoma in the posterior triangle of the neck.

## Key findings

- Pleomorphic adenoma was diagnosed in the posterior triangle of the neck via pathological and imaging studies.
- Complete surgical excision via the transcervical approach was successfully performed.
- The case emphasizes the diagnostic difficulty of soft tissue tumors in the head and neck region.

## Abstract

Diagnosing a soft tissue tumor in the head and neck region can be challenging due to its complex anatomy and diverse histological spectrum. This case report highlights the case of a woman who presented with a painless neck lump in the posterior triangle of the neck. Various pathological and imaging studies were suggestive of pleomorphic adenoma, which arises from the left prevertebral space. The patient underwent complete surgical excision via the transcervical approach. Pleomorphic adenoma in the posterior triangle of the neck is extremely rare and causes a diagnostic dilemma in managing soft tissue tumors of the neck.
