Cyclic neutropenia is a rare hematologic disorder characterized by a periodic decrease in blood neutrophil counts, accompanied by recurrent episodes of oral aphthae, fever, malaise, and skin infections with a periodicity of approximately 21 days. In 1989, the first report of effective treatment of cyclic neutropenia with granulocyte colony-stimulating factor (G-CSF) was published by Hammond et al,1 and further reports describing other patients successfully treated followed.2 We describe a young girl with a history of recurrent episodes of painful oral aphthae and fever dating from early childhood, with recurrent aphthous stomatitis associated with cyclic neutropenia, treated successfully with G-CSF.
Report of a Case.
A 16-year-old girl had recurrent episodes of oral aphthae, gingivitis, malaise, and fever since she was 6 months old, which recurred every 3 weeks. Her mouth lesions varied in severity, but usually were extremely painful and took 4 to 5 days to run their course.
