case report and literature review

L

angerhans cell histiocytosis (LCH) is a group of three rare diseases (annual incidence less than 4/1000.000H) with increasing

aggressiveness respectively: Eosinophilic granuloma (unifocal solitary osteolytic lesion), Hand-Schuller-Christian disease

(multifocal lesion) and Letterer-Siwe disease (themost aggressive, disseminated disease with systemicmanifestations). e bone

is most commonly involved with a predilection for the skull. Some cases of temporal bone localizations have been described

in the literature. We report a case of an 18-month child presenting a LCH of the temporal bone misdiagnosed at the beginning

as osteoarthritis. In fact, the child presented a retro-auricular swelling with in ammatory characters, fever and otorrhea. e

exploration before surgery revealed besides the extensive temporal lesion, hematologic perturbations, a splenomegaly and

a hepatomegaly. e histopathology con rmed the diagnosis of a LCH. We describe the diagnosis challenges, the surgical

di culties and the therapeutic response of the child.
