Acquired Torticollis as Presentation of Langerhans Cell Histiocytosis: Two Contrasting Cases

Abstract

Langerhans cell histiocytosis (LCH) is a rare disorder that primarily affects young children. Because LCH can affect multiple organs, particularly bone and skin, it presents with a wide range of symptoms. This article reports two different cases with acquired torticollis as the primary complaint. Acquired torticollis is an atypical and less common presentation of LCH. These case reports highlight the importance of identifying a cause for acquired torticollis, which includes LCH in the differential diagnosis. Adequate diagnosis of LCH is important for timely initiation of appropriate treatment to prevent complications and long-term consequences.
