Soft Tissue Masses of the Hand

Area of Science:

• Musculoskeletal Radiology
• Oncology
• Pathology

Background:

• Solid soft tissue masses in the hand are common and diverse.
• Most hand masses are benign, but accurate diagnosis is crucial for appropriate management.
• Distinguishing benign from malignant lesions prevents unnecessary interventions.

Purpose of the Study:

• To review solid soft tissue tumors of the hand based on the 2020 WHO Classification.
• To emphasize key imaging features and clinical presentations for common hand masses.
• To integrate current (2023) European Society of Musculoskeletal Radiology guidelines for soft tissue lesion imaging.

Main Methods:

• Review of solid soft tissue tumors of the hand.
• Emphasis on imaging features and clinical presentation.
• Adherence to the 2020 WHO Classification of Soft Tissue Tumors.
• Incorporation of 2023 European Society of Musculoskeletal Radiology guidelines.

Main Results:

• Characteristic imaging features aid in diagnosing common entities like lipomas, tenosynovial giant cell tumors, glomus tumors, and nerve sheath tumors.
• The review covers various pseudolesions, such as traumatic neuromas.
• Imaging findings are correlated with the 2020 WHO Classification.

Conclusions:

• Accurate diagnosis of hand soft tissue masses is essential for guiding management.
• Imaging plays a pivotal role in differentiating benign from potentially malignant lesions.
• Referral to specialized sarcoma centers is recommended for indeterminate or aggressive lesions.
