Cyclic neutropenia: a cause of recurrent aphthous stomatitis not to be missed.

ABSTRACT

Cyclic neutropenia is a rare hematological disorder consisting of recurrent episodes of aphthous stomatitis and skin infections caused by a periodic decrease in blood neutrophil counts. We present the case of such a patient successfully treated with steroids. Recurrent aphthous stomatitis with a periodicity of around 3 weeks should alert the dermatologist to the possibility of cyclic neutropenia.
