# The Clinical, Radiological, and Histopathological Characteristics of Intramuscular Myxoma: A Case Report

## TL;DR

This case report describes a rare benign tumor called intramuscular myxoma in a 47-year-old woman, including its clinical features, imaging results, and treatment through surgery.

## Contribution

The paper contributes a detailed case report with diagnostic and treatment insights for intramuscular myxoma, emphasizing its distinction from malignant tumors.

## Key findings

- Intramuscular myxoma was diagnosed through imaging and histopathological analysis in a 47-year-old female.
- Surgical excision led to a straightforward recovery with low recurrence risk.
- Accurate diagnosis is crucial to differentiate IMM from malignant soft tissue tumors.

## Abstract

In this study, we discuss the clinical, radiological, and histopathological characteristics of intramuscular myxomas (IMM), a rare form of benign soft tissue tumors. We report the case of a 47-year-old female patient presenting with a painless, non-inflammatory mass in the right thigh, which was mobile relative to both superficial and deep planes. Imaging, biopsy, and subsequent histopathological study established the diagnosis of intramuscular myxoma. The patient underwent surgical excision of the mass, with a straightforward postoperative course. It is important to distinguish IMM from malignant tumors, such as soft tissue sarcomas, through comprehensive examinations including imaging and biopsy. The recommended treatment is surgery for complete excision of the mass, with an exceptionally low recurrence rate.
