Lymphoma Presenting as a Soft Tissue Mass

Area of Science:

• Oncology
• Pathology
• Radiology

Background:

• Lymphoma typically affects lymph nodes, but can involve extranodal sites.
• Skeletal muscle involvement by lymphoma is a rare clinical presentation.
• Accurate diagnosis is essential for timely and appropriate patient management.

Observation:

• This case highlights the importance of considering lymphoma in the differential diagnosis of soft tissue masses.
• Imaging findings can be nonspecific, requiring a high index of suspicion.
• Histopathological examination is crucial for definitive diagnosis.

Findings:

• Lymphomatous infiltration of skeletal muscle can mimic other soft tissue tumors.
• Early recognition of extranodal lymphoma is key.
• Chemotherapy is the primary treatment modality for lymphoma.

Implications:

• Clinicians and radiologists should include lymphoma in the differential diagnosis of unexplained soft tissue masses.
• Prompt diagnosis can lead to improved outcomes with chemotherapy.
• Further research into the imaging characteristics of skeletal muscle lymphoma may be beneficial.
