Cavitary lung lesions in systemic lupus: an unusual presentation

Area of Science:

• Rheumatology
• Pulmonology
• Hematology

Background:

• Systemic lupus erythematosus (SLE) is a complex autoimmune disease with diverse clinical presentations.
• Pulmonary manifestations in SLE are common but cavitary lung lesions are rare.
• Potential causes of lung cavitation in SLE include infection, embolism, and vasculitis.

Observation:

• A male patient presented with symptomatic lung cavitations.
• The patient was diagnosed with SLE, secondary antiphospholipid syndrome, and plasma cell dyscrasia.
• The cavitary lung lesions showed significant improvement following immunosuppressive treatment.

Findings:

• This case highlights a rare presentation of SLE with cavitary lung disease.
• The patient's condition improved with immunosuppressive therapy, suggesting an autoimmune or inflammatory etiology.
• The co-occurrence of SLE, antiphospholipid syndrome, and plasma cell dyscrasia may influence the manifestation and treatment of pulmonary complications.

Implications:

• This case expands the understanding of pulmonary involvement in SLE.
• It underscores the importance of considering autoimmune and hematologic conditions in patients with unexplained lung cavitations.
• Prompt diagnosis and appropriate immunosuppressive therapy can lead to favorable outcomes in SLE-related lung disease.
