Necrobiotic xanthogranuloma: a 30-year single-center experience

Area of Science:

• Dermatology
• Hematology
• Oncology

Background:

• Necrobiotic xanthogranuloma (NXG) is a rare, non-Langerhans cell histiocytosis.
• It is characterized by xanthomatous lesions and often associated with systemic conditions.

Purpose of the Study:

• To characterize the clinical features of NXG.
• To identify associated disorders and evaluate treatment outcomes.

Main Methods:

• Retrospective review of pathologically confirmed NXG cases.
• Data extraction on clinical, laboratory, and treatment information.

Main Results:

• Nineteen patients were identified with a mean age of 54 years.
• 84% had detectable monoclonal protein; 53% had periorbital lesions.
• Extracutaneous manifestations (liver, sinuses) and hematologic malignancies (26%) were common.

Conclusions:

• NXG is a reactive histiocytic disorder involving multiple organ systems.
• High clinical suspicion is crucial for diagnosis.
• Treatment should consider comorbidities and disease patterns.
