Resolution of eosinophilic granuloma of the mandibular ramus and condylar neck following minimal intervention—Report of a case and review of literature

Langerhans’ cell histiocytosis is a collective term used to describe a group of enigmatic, proliferative disorders. The natural history of the disease varies from a slow, benign, localized, symptomatic bony or soft-tissue lesion, to a rapidly, progressive, widespread, multiple-organ disorder which is often fatal. Eosinophilic granuloma (EG) accounts for 60–70% of all cases of Langerhans’ cell histiocytosis and can present as solitary (50–75%) or multifocal defects in bone. It occasionally presents as a localized soft-tissue lesion. Multiple treatment options are available but the response is unpredictable. However, no studies show complete resolution following a conservative modality of treatment in the management of EG of condyle and ramus. We describe a case, treated with intralesional injections of triamcinolone acetonide (Tricort 40 mg/ml, 6 injections at weekly intervals over 6 weeks), leading to complete resolution of the lesion, along with a brief mention of the review of literature.
