The most common presentation in ECD is the presence of periorbital xanthelasma-like lesions. Other presentations include nonfacial cutaneous xanthomas, panniculitis-like lesions and granuloma annulare-like lesions. Associated symptoms at presentation include bone/extremity pain and weight loss. What's already known about this topic? Erdheim-Chester disease is a rare form of non-Langerhans cell histiocytosis characterized by lipid-laden macrophage infiltration of tissue and subsequent fibrosis. Cutaneous involvement is found in approximately 25% of patients, with the majority presenting with periorbital xanthelasma-like lesions. What does this study add? We report two novel cutaneous findings: panniculitis-like lesions and granuloma annulare-like lesions. Associated bone/extremity pain and weight loss should raise suspicion for Erdheim-Chester disease.
