Lupus erythematosus hypertrophicus et profundus

Area of Science:

• Rheumatology
• Immunology
• Hematology

Background:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse clinical manifestations.
• Lupus erythematosus hypertrophicus et profundus is a rare, severe subtype characterized by deep cutaneous and subcutaneous lesions.
• Serological abnormalities are common in SLE, reflecting immune system dysregulation.

Observation:

• A patient presented with sudden onset of severe lupus erythematosus hypertrophicus et profundus.
• Extensive serological abnormalities were detected, including antinuclear antibody (ANA) positivity, leukopenia, and anemia.
• The patient also exhibited decreased serum complement levels, abnormal renal function, and positive immunofluorescence findings.

Findings:

• The patient's serological profile was notable for the presence of antibodies against clotting factors.
• This finding suggests a potential link between autoimmune processes in SLE and coagulation system abnormalities.
• The combination of cutaneous lupus and clotting factor antibodies presents a complex clinical picture.

Implications:

• This case underscores the importance of comprehensive serological evaluation in patients with severe cutaneous lupus.
• The presence of antiphospholipid antibodies or other clotting factor antibodies may indicate an increased risk of thrombotic events.
• Further research is warranted to elucidate the mechanisms linking lupus erythematosus hypertrophicus et profundus with coagulation disorders.
