UNLABELLED The authors present a case of a 4-year old boy with a quickly growing tumor of the jaw. The CT examination revealed a destructive tumor in the body of the mandible involving soft tissues. A diagnosis of eosinophilic granuloma of the mandible was confirmed by a biopsy of the tumor. Skeletal scintigraphy showed areas of increased and decreased radiotracer uptake. The fusion of CT and s...

The radiological diagnosis of osteolytic lesions of the long bones in pediatric population constitutes a challenge when the case history and clinical data are uncharacteristic. We believe that the description of few clinically and histologically proven cases to verify the existence of radiological signs useful for diagnosis may be of interest. Here, we describe a case of Langerhans' cell histio...

Langerhans cell histiocytosis (LCH) is a rare neoplastic lesion characterized by accumulation of cells having major phenotypic features of skin Langerhans cells. It usually affects young children but rare cases were also reported in adults. The clinical spectrum of LCH includes Letterer–Siwe disease, Hand–Schüller–Christian disease, eosinophilic granuloma, Langerhans cell sarcoma as well as int...

UNLABELLED Langerhans cell histiocytosis (LCH), which is a rare granulomatous pediatric disease of unknown etiology, is characterized by the idiopathic proliferation and accumulation of abnormal and clonal Langerhans cells or their marrow precursors, resulting in localized, solitary or multiple destructive lesions. These lesions are most commonly eosinophilic granuloma, which are found in crani...
