Eosinophilic Granuloma: A Rare and Often Benign Condition Presenting as a Lump on the Head, which was Easily Treated

Abstract

Eosinophilic granuloma is a localized, non-invasive form of Langerhans cell histiocytosis. It usually develops in the long bones and is more frequent in children under the age of 10 years. It is very rare in adults. We present the case of a young woman admitted to hospital for persistent refractory left parietal headache, later revealed to be caused by an eosinophilic granuloma.
