Squamous cell carcinoma and eosinophilia in a long-term course of pansclerotic morphea

Area of Science:

• Dermatology
• Rheumatology
• Rare Diseases

Background:

• Pansclerotic morphea is an exceptionally rare subtype of localized scleroderma, with limited documented cases.
• Understanding its long-term clinical course and potential complications is crucial for patient management.

Observation:

• A young male patient with a 15-year history of pansclerotic morphea is presented.
• The patient experienced recurrent squamous cell carcinomas with high-risk features and frequent cellulitis, necessitating numerous hospital admissions.
• Autoimmune markers were negative, but marked eosinophilia was observed later in the disease progression.

Findings:

• Pansclerotic morphea demonstrates a challenging clinical course with severe complications, including malignancy.
• The disease is characterized by resistance to conventional treatments.
• Immunosuppressive therapy showed potential in slowing progression but did not achieve a cure.

Implications:

• This case underscores the need for vigilant monitoring for complications such as squamous cell carcinoma in pansclerotic morphea patients.
• Further research into effective treatment strategies for this rare and aggressive condition is warranted.
• The findings suggest a complex pathophysiology, potentially involving factors beyond typical autoimmune markers.
