We report a pediatric case of multiple XGJ without visceral involvement in a 6-month-old female infant who was hospitalized with disseminated congenital skin nodules, of firm consistency, of variable diameter ranging from a few millimetres to 1 cm, involving the face, scalp, trunk and limbs. There was no mucosal localization. The remainder of the somatic examination was unremarkable. The diagnosis of disseminated XGJ was confirmed by skin biopsy without visceral or systemic involvement. Therapeutic abstention was recommended. This observation underlines the fact that XGJ is a rare clinical entity that should not be overlooked when faced with congenital skin nodules.展开更多

Tracheal involvement of JXG is extremely rare, and only few cases have been reported in literature. Herein we presented an additional new case and discussed the optimal management of this uncommon disease.展开更多

Whose etiology is unknown. The nature of these lesions is controversial and could be either reactive or neoplastic;the presence of monoclonal cells does, however, favor the second hypothesis. Xanthogranuloma is frequently found in young adults and children(under 20 years old), mainly in the skin. In about 5%-10% of all Juvenile XG(JXG) cases xanthogranuloma are extracutaneous. Within this group, the site most frequently involved is the eye. Other involved organs are heart, liver, adrenals, oropharynx, lung, spleen, central nervous system and subcutaneous tissue, although involvement of the spine is uncommon. Isolated lesions involving the sacral region are extremely rare. To date, this is the first reported case of a giant JXG arising from S1 with extension into the pelvic region in an adult spine.展开更多
