Abstract
BACKGROUND

Proliferative myositis is a rare benign tumor that is typically self-limiting and does not become malignant. It can be cured by simple resection without reported recurrence. Due to its rapid growth, hard structure and ill-defined borders, it can however be mistaken for malignant tumors such as sarcomas.

CASE SUMMARY

We investigate the case of a 64-year-old male with proliferative myositis of the abdominal wall, who was preoperatively administered a needle aspiration biopsy and given a simple excision and patch repair. We then compared it with other similar cases to determine the effectiveness of this treatment method.

CONCLUSION

Resection with follow-up observation has shown to be an effective treatment method for proliferative myositis. To avoid unnecessarily extended or destructive resection, a thorough and conclusive diagnosis is crucial, which requires adequate imaging and pathological knowledge.

Core Tip: Proliferative myositis is a rare and self-limiting benign tumor. Although preoperative imaging can identify certain characteristics, it is still difficult to achieve a conclusive diagnosis. Most cases are not diagnosed until after surgical resection. A needle biopsy is helpful in the diagnosis of proliferative myositis, and surgery involving local excision is sufficient. When the resected mass is located in the abdominal wall, local defects can be considered for patch repair. The key to treatment lies in avoiding misdiagnosis as a malignant tumor, resulting in excessive extended resection and corresponding trauma.
