title: Langerhans' cell histiocytosis of the temporal fossa: A case report.
abstract: Langerhans' cell histiocytosis (LCH) is a rare disease with a wide spectrum of clinical manifestations, varying from an isolated lesion to systemic involvement. The etiology of this disease remains to be elucidated. The present study reports a case of LCH with temporal fossa localization in an 8-year-old male patient, who had exhibited left temporal pain and headache for 1 month. Physical examination revealed slight exophthalmos and conjunctival hemorrhage in the patient's left eye, and non-contrast computed tomography imaging of the head revealed a soft tissue mass with unclear margins located in the left temporal fossa, as well as a wide bony defect. Magnetic resonance imaging revealed a heterogeneously contrast-enhanced mass near the left temporal pole, which eroded into the patient's left orbit and maxillary sinus. The lesion was totally excised and confirmed to be LCH through biopsy.
