Additional Types of Neutropenia Neutropenia is most common during or after a patient receives chemotherapy to treat cancer. However, according to the Neutropenia Support Association Incorporated, there are several rare types of neutropenia that may affect both adults and children. Symptoms include frequent fevers, mouth sores, ear infections, pneumonia, or rectal sores. If untreated, many children may lose their teeth or develop severe gum infections. The most severe form of chronic congenital neutropenia is called Kostmann's Syndrome.
Cyclic neutropenia tends to occur every three weeks and last three to six days at a time.
Symptoms include fever, illness, and mouth ulcers. Children with cyclic neutropenia usually improve after puberty. The Neutropenia Support Association Inc. is a registered charity formed in 1989 to increase awareness and understanding of neutropenia. The association provides assistance to neutropenic patients and their families and also raises money for research and education.
