Erythema Elevatum Diutinum: A Rare Case Wth Atypical Presentation

Area of Science:

• Dermatology
• Pathology

Background:

• Erythema elevatum diutinum (EED) is a rare chronic vascular dermatosis.
• EED typically presents as painless plaques and nodules on extensor surfaces.
• The exact cause of EED is unknown, but associations with autoimmune diseases, infections, and cancers exist.

Observation:

• A 56-year-old woman presented with an unusual form of EED.
• Initially painless nodules evolved into painful lesions affecting hands, feet, knees, and back.
• Histopathological examination confirmed EED, with further tests ruling out systemic conditions.

Findings:

• The patient's EED exhibited atypical painful manifestations.
• Standard medical therapies were insufficient for symptom relief.
• Surgical excision and split-thickness skin grafting (SSG) were performed.

Implications:

• This case emphasizes the diverse clinical presentations of EED, including pain.
• It highlights the importance of considering atypical symptoms in EED diagnosis.
• A multimodal treatment approach, including surgery, may be necessary for refractory EED.
