Mastocytosis with Skeletal and Gastrointestinal Involvement in Infancy

Abstract

Two cases of mastocytosis with skeletal involvement in children three and six months old are reported. Bone lesions, either sclerotic or lytic, were encountered in their skeletal surveys. Gastrointestinal lesions in children with mastocytosis are exceedingly rare; in addition to skeletal lesions, one of our patients had a large duodenal ulcer. The diagnosis of mastocytosis was established by skin biopsy in both patients. A review of the literature is also presented.
