- Abstract: Langerhans cell histiocytosis (LCH) is a rare condition in adults, especially when it is limited to a single area of the skull, known as solitary calvarial involvement. In this case report, we present a unique instance of LCH affecting the parietal bone with a pus-draining fistula. This is a rare and unusual presentation at this location, which has been scarcely reported in medical literature. A 30-year-old woman with no prior comorbidity presented with complaints of headache that persisted for a year. She also had swelling on her scalp and a yellowish discharge for 3 weeks, but no neurological problems were observed. Radiology revealed thinning of the calvaria, with ragged margins along the inner table, multiple focal erosions, and involvement of overlying soft tissue and bony sequestrum. The patient underwent biparietal craniotomy and excision of the lesion. The histopathology report showed LCH. After 8 months of follow-up, there was no recurrence. The management of solitary calvarial involvement by LCH with masquerading presentation as a scalp infection can be achieved through complete excision of the lesions, resulting in a favorable outcome.
