A Case of Eosinophilic Granuloma Presenting as Post-traumatic Scalp Hematoma

206 Eosinophilic granuloma is a benign bone disease which is local. It is a mild form of Langerhans cell histiocytosis (LCH). Children, adolescents, and young adults are predominantly affected. The most common site of involvement is the skull.1 Although eosinophilic granuloma (EG) can be asymptomatic and incidentally found, it can be seen as tender, growing scalp mass. A mild head trauma history before clinical symptoms is common.
